Review: Color night vision with the SiOnyx Aurora

25 Nov

As someone who frequently photographs the night sky and nocturnal landscapes, I was intrigued by the recently announced SiOnyx Aurora IR Night Vision Camera. The Aurora is a compact camera designed to shoot stills and video in color under low light conditions, in addition to providing night vision capability.

The camera is marketed for outdoor enthusiasts (e.g., boaters, fishermen, hunters, hikers) who need to see in the dark and might want to capture their nocturnal activities. At a retail price of $ 799 it’s more than an impulse buy, but it promises some impressive capabilities. Being an aurora photographer, I was interested in its performance capturing the Northern Lights so I took the Aurora to Yellowknife, Canada.

Key specifications

  • ‘Ultra-low-light’ 1″-type CMOS sensor
  • 1280×720 resolution (stills and video)
  • 16mm (47mm equiv) lens
  • Three shooting modes: Night (F1.4), Twilight (F2.0), and Day (F5.6)
  • Image stabilization
  • Video frame rates from 7.5 to 60 fps
  • OLED viewfinder
  • IP67 water resistant

Night Vision

The SiOnyx Aurora features a one-inch-type ultra low light CMOS sensor—sensitive to both visible and infrared light —capable of capturing stills and video in either monochrome or color, though it’s limited to shooting stills and video at 1280×720 resolution.

This resolution may seem low by today’s standards but it makes sense for a night vision camera. In everyday photography pixel size has very little effect on image quality, other than that small pixels give more detail. However, the tiny advantage that large pixels can have can become significant in extreme low-light situations, which means a night vision camera is one of the few instances where bigger pixels offer a recognizable benefit.

The SiOnyx Aurora features a 1″-type ultra low light CMOS sensor sensitive to both visible and infrared light. It also includes effective image stabilization for handheld use in dark conditions.

Resolution and pixel size aside, as soon as I picked up the Aurora it became evident that its compact size and light weight were going to put this camera in its own category. The water-resistant Aurora is 11.7 cm (4.6″) long and weighs only 227 g (8 oz) so it fits easily in a jacket pocket. Its portability and the fact that a tripod is not required to shoot at night means that the Aurora can always be within reach and ready to shoot.

The Aurora has three shooting modes for daytime (F5.6), twilight (F2.0), and nighttime (F1.4) scenes. The daytime setting performs as expected but the twilight mode performs well only for a short window of time. My impression was that I needed to change the dial to the night setting long before twilight was over. When you rotate the dial from Twilight to Night, the infrared filter is removed from the optical path. The Night scene mode is the most useful (and fun) since at that setting the camera captures light at wavelengths way beyond what the human eye can see. Specifically, its wavelength range goes from blue (400 nm) to infrared (1,100 nm). In comparison, the human eye can see from blue (400 nm) to red (700 nm).

All videos below are straight-out-of-camera and were shot handheld.

The Night scene mode has three color settings collectively referred to as ‘Night Glow’: Grayscale and Green, both useful when there’s almost no artificial light and barely any natural light, and Night Color, beneficial when viewing colors is important, as in the case of the Northern Lights.

Point, Focus, and Shoot in the Dark

The benefits of the Aurora for hunting, fishing, and other outdoor enthusiasts is very apparent, but I wanted to see how useful it would be to capture video of the Northern Lights. Since most of the time the Northern Lights move slowly, time-lapse photography with exposures of several seconds is the perfect technique to capture them. That way, we get to capture more light with long exposures and we get to compress (or speed up) time by playing the frames at a higher rate than those at which they were taken.

During a substorm the lower end of an aurora curtain can move at speeds exceeding 5 km/s and look motion-blurred in time-lapse sequences. The higher frame rate of video works better to capture the substorm motion…

Nevertheless, time-lapse photography might not be the best technique to capture a substorm: the sudden brightening and increased movement of auroral arcs that can last for tens of minutes. During a substorm the lower end of an aurora curtain can move at speeds exceeding 5 km/s and look motion-blurred in time-lapse sequences. The higher frame rate of video works better to capture the substorm motion, but the shorter exposure for each frame results in lower signal-to-noise ratios and lower image quality.

I set the camera to the Night Color mode, the frame rate to 30p, and set focus to infinity. Once a substorm started all I had to do was to take the camera out of my pocket, turn it on, and press record. The electronic viewfinder (EVF) shows you exactly what you are capturing so it is very easy to point, shoot, and follow your subject.

As expected, the SiOnyx Aurora works best when the Northern Lights are at its brightest, and you can see how the video gets noisier when the lighting conditions are darker (0:20 and 1:08 marks on the video above). Also, the Auto White Balance appears to shift during faint periods (1:33 mark). Overall, the camera captured the colors and rapid motion of the substorm well.

The images above are video frames taken from the SiOnyx Aurora camera. Both video and still images from the camera have a resolution of 1280×720.

A few nights later I shot a brighter auroral substorm from the side of a road. The infrared light reflected by nearby trees at the beginning of the video below indicates that the ambient light at that location was also brighter. Note that the infrared light detected by the camera comes from objects reflecting it and not emitting it. In other words, the camera does not detect thermal emission (light emitted due to the temperature of matter).

This brighter auroral substorm resulted in a video with lower noise. Notice the infrared light reflected by vegetation and the very fast motion of the aurora around 0:25. Download original
The SiOnyx Aurora outputs JPEG stills and MOV (H.264) video files with audio. Unless otherwise noted, images in this articles are frames from videos files. To compare the quality of a JPEG with the quality of a video frame, I shot a still in Color Night mode (F1.4) with an exposure of 1/30 sec at ISO 20,000 and compared it with a frame of a video of the same scene shot in Color Night mode (F1.4) at 30p. I can only assume that the chosen ISO (the Aurora always operates in Auto ISO) was 20,000 as well.

The video frame looks cleaner and the edges look slightly sharper but the shadows are clipped. This could be the result of further image processing and video compression. One definite advantage of shooting stills is the ability of taking exposures as long as 1.5 seconds.

Comparison of a still image with an exposure of 1/30 sec at ISO 20,000 and a frame from a video shot at 30p. Both were shot in Color Night mode (F1.4). The foreground tree was illuminated by a street lamp.

To see how the SiOnyx Aurora compares to another camera that performs well in low light conditions, I shot two scenes with the Aurora (set to Color Night mode) and with the Nikon D5 with a Nikkor 50mm F1.4G. Both image sets were shot with the same exposure parameters.

Still image shot with the SiOnyx Aurora: 1/30 sec, F1.4, ISO 20,000 Still image shot with a Nikon D5 and a Nikkor 50mm F1.4G: 1/30 sec, F1.4, ISO 20,000. Sampled down to 1280 px wide.
Still image shot with the SiOnyx Aurora: 1/15 sec, F1.4, ISO 102,400 Still image shot with a Nikon D5 and a Nikkor 50mm F1.4G: 1/15 sec, F1.4, ISO 102,400. Sampled down to 1280 px wide.

Not surprisingly, given its relatively low resolution, the images from the SiOnyx camera are not as sharp and clean as those shot with the Nikon D5, but they do show more vegetation due its extended range into the infrared part of the electromagnetic spectrum. The second scene was too dark for the unaided eye to clearly perceive and, while I was able to easily focus using the Aurora EVF, it was impossible for me to focus using the D5 viewfinder or Live View mode. It is evident that the advantages of the Aurora are its infrared sensitivity, bright EVF, ease of use, compactness, and light weight.

The Aurora sports a fixed 16mm lens (47mm equivalent in full frame terms) which provides a diagonal FOV of 48 degrees. Although, I wished I had a wider FOV to capture the auroral displays, I think the fixed 48-degree FOV is a good compromise for most uses. Lens focus is manual only, but I was surprised how easy it was for me to focus in the dark thanks to the bright OLED EVF. Additionally, the camera features focus peaking, which displays a red highlight on in?focus edges.

Features Galore

The Aurora is packed with shooting features including shutter speeds from 1.5 sec to 1/8,000 sec, burst mode (2.5, 5, or 10p), HDR, self-timer (2, 5, or 12 sec), panorama (up to 180 degrees in landscape or portrait mode), and time-lapse. Video frame rates range from 7.5 to 120p. The Aurora also features Electronic Image Stabilization and remote operation using the SiOnyx mobile app (iOS and Android).

Lens focus is manual only, but I was surprised how easy it was for me to focus in the dark thanks to the bright OLED EVF.

Its EVF displays shooting parameters and modes, current time, compass direction, GPS coordinates, and optionally, focus peaking, grid (to aid in image composition), and pitch & roll (to aid in keeping the camera level in two axes).

The EVF has the option to turn itself on only when you move your face close the eyepiece. Although this definitely helps to save power (from a standard Fujifilm-style NP-50 lithium ion battery) I thought that battery life was very limited. Fortunately, the Aurora can draw power from an external source via USB. (NB: For this to work you still need a battery inside the camera). This is very helpful, for example, when taking long time-lapse sequences.

The SiOnyx app lets you connect remotely to the Aurora via Wi-Fi to: browse and delete content in the microSD card, change settings, and shoot stills and video.

Final Thoughts

Not only can the Aurora capture video and stills at night, but the list of uses (thanks to its bright EVF) in wildlife watching, hunting, boating, fishing, and other nocturnal outdoor activities is long.

I think it’s important to stress what the camera is not for. It’s neither designed for capturing high-resolution images for prints or HD monitors nor for shooting video for professional productions. Hence, it is not in the same category as low-light mirrorless cameras or DSLRs. The camera is very useful as a device to do tasks in the dark—especially when safety might be an issue—and to capture outdoor activities and the natural world at night in a fun and easy way.

Video frame of Northern Lights tour participants warming up and waiting for the natural spectacle to begin.

I benefit tremendously from using high-end DSLRs to take long exposures and time-lapse sequences of natural phenomena. I don’t see the SiOnyx Aurora as a substitute to my equipment but as a complement instead.

I’ll let my high-end DSLRs do what they do best—capture time-lapse sequences for my science films—and use the Aurora to capture nocturnal videos that allow me to demonstrate phenomena in my science lectures (e.g., how fast can the Northern Lights appear to move). As a science communicator, handheld videos shot in real time, especially with audio, help me bring audiences closer to the natural phenomena I present and, as a photographer, the fact that I can take this camera out of my pocket and be ready to shoot in seconds is a big plus.

As a science communicator, handheld videos shot in real time, especially with audio, help me bring audiences closer to the natural phenomena I present…

Does the SiOnyx Aurora let me see things in the dark that I can’t see with the unaided eye? Absolutely: the infrared sensitivity makes a big difference and, hence, my stress on the night vision capability of this device. The fact that you can also capture what you see is a plus. For me it was capturing Northern Lights, but I’m also looking forward to capturing surface lava flows in Hawaii, bioluminescence in Puerto Rico, as well as other phenomena around the world.

What we like:

  • Pocketable, always with you size
  • Easy to operate in the dark
  • High enough image quality for instructional use or social media
  • Image stabilization

What we’d like to see improved:

  • A dial less prone to accidentally turning off the camera
  • Ability to set white balance manually
  • Video metadata saved to XMP file (GPS coordinates, direction, etc.)
  • A hot shoe (for accessory lights)
  • A lens cap

Photokina 2018: Hands-on with Sigma’s new Global Vision lenses

26 Sep

A closer look at Sigma’s new Global Vision lenses

Six years after launching the Global Vision line at this very show in 2012, Sigma took the wraps off five new lenses at Photokina this year, and we were there at the launch event to see (and handle) them for ourselves. Click through for more information and some early first impressions.

First up is the new 56mm F1.4 DC DN ‘Contemporary’ for Sony APS-C format E-mount cameras and M43 – where it provides an equivalent focal length of 84mm and 112mm, respectively.

A closer look at Sigma’s new Global Vision lenses

At 280g (9.9 oz) the 56mm is a very lightweight lens, and with the lenshood (shown in the previous slide) removed, it’s actually the smallest of Sigma’s current fast-aperture E-mount / M43 primes.

A closer look at Sigma’s new Global Vision lenses

Optical construction consists of 10 elements in six groups, and the lens features a nine-bladed aperture. We weren’t able to use it on a camera, but Sigma claims that ‘smooth autofocus’ should make this lens ideal for video use. Pricing and availability will be confirmed at a later date.

A closer look at Sigma’s new Global Vision lenses

Next up is the latest in Sigma’s range of wide-aperture ‘Art’ series primes for full-frame ILCs – the 28mm F1.4 DG HSM. Compared to the 56mm, this fast wideangle prime is quite a hefty piece of glass, but if performance is in line with its stablemates, it should be capable of great things.

Sigma tells us that its benchmarks were Nikon and Zeiss’s 28mm F1.4 primes, and performance from its new Art-series option should be ‘best in class’.

A closer look at Sigma’s new Global Vision lenses

Key to the 28mm F1.4’s claimed performance is its optical makeup, which comprises 17 elements in 12 groups, including no fewer than three aspherical elements, two FLD and three SLD (“F” low-dispersion and ‘Special’ low-dispersion respectively) elements. Sigma claims that this design provides ‘thorough’ correction of chromatic aberration and minimal distortion.

A closer look at Sigma’s new Global Vision lenses

Unlike Sigma’s earliest Art-series primes, the new range are weather-sealed, and employ water and oil-repellant coating on their front elements. The 28mm F1.4 certainly feels like a solid professional tool, but Sigma has yet to confirm its actual weight.

A closer look at Sigma’s new Global Vision lenses

Price, likewise, is TBD but we understand that the upcoming 28mm F1.4 will be somewhere around $ 1300, pre-tax.

A closer look at Sigma’s new Global Vision lenses

Even larger and even heavier is the 40mm F1.4DG HSM. Created from Sigma’s 40mm cine lens, the company claims that this fast standard prime is its sharpest ever lens of this type.

A closer look at Sigma’s new Global Vision lenses

As you can hopefully tell from our pictures, it’s a big lens, measuring 87.8mm x 131mm (3.5in. x 5.2in) and weighing in at 1.2 kilos (43 oz). An 82mm filter ring is bigger than most, but not quite as bonkers as the 95mm thread on Canon’s new 28-70mm F2!

Like Sigma’s 28mm F1.4, the 40mm F1.4 is dust and moisture-sealed.

A closer look at Sigma’s new Global Vision lenses

Designed to satisfy the resolution requirements of 50MP sensors and 8K video, the 40mm F1.4 is highly corrected for distortion (which, it is claimed, is below 1%) and coma. Optical construction consists of 16 elements in 12 groups, including three FLD and three SLD elements. Pricing and availability have yet to be confirmed.

A closer look at Sigma’s new Global Vision lenses

This is a lens that Sigma fans (and photography fans in general) have been waiting for, for some time: the new 70-200mm F2.8 DG OS HSM ‘Sports’ While not an ‘Art’ series lens, the 70-200mm was designed to meet the needs of the most demanding professional photographers, and the company claims that it will be competitive with own-brand equivalent lenses from the other major camera manufacturers. This shot shows off the various focus and OS switches, and the removable Arca-Swiss compatible tripod mount collar.

A closer look at Sigma’s new Global Vision lenses

The 70-200mm F2.8 makes generous use of magnesium alloy in its construction, for strength and low weight. Sigma processes this material in-house, at a brand new factory built at its existing site in Aizu, Japan. In keeping with other Sport-line lenses, it is dust and weather-sealed, and features and oil and water-repellant coating on the front element.

A closer look at Sigma’s new Global Vision lenses

Optical construction of this internal zoom lens is pretty impressive on-paper, comprising 24 elements in 22 groups, including ten low-dispersion elements – nine ‘FLD’ and one SLD. Sigma claims that this advanced optical makeup ensures attractive bokeh and excellent correction of color aberrations. On the mechanical side, ‘intelligent OS’ is capable of correcting for shake in all directions, with total shake-reduction effectiveness still to be confirmed. Ergonomically, while we couldn’t mount it on a camera (we’re hoping to do that soon!) the lens feels exceptionally nicely made and very well-balanced, and some photographers will be pleased to see that Sigma has put the zoom ring at the front of the lens.

An AF function button can be customized either via the host camera or Sigma’s USB Dock, and the 70-200mm will be available in Canon EF, Nikon F and Sigma SA mounts, pricing and availability still TBD.

A closer look at Sigma’s new Global Vision lenses

Last but definitely not least is the 60-600mm F4.5-6.3 DG OS HSM. A beast of a lens (that’s a technical term) this 10X sports zoom is among Sigma’s most versatile, capable of covering everything from goalmouth action at one end of a football pitch to goalmouth action at the other end without swapping lenses.

A closer look at Sigma’s new Global Vision lenses

Relatively compact at 60mm (relatively…) at 600mm, this lens is quite a handful, and in terms of optical construction it just beats out the other four lenses released by Sigma by featuring 25 elements, in 19 groups. Like the 70-200mm, the 60-600mm is partially constructed using magnesium alloy from Sigma’s new factory.

A closer look at Sigma’s new Global Vision lenses

The 60-600mm is highly customizable, and usefully it features a zoom lock at all zoom positions, to help prevent ‘zoom creep’ when you’re trying to frame shots. It will be available in late October for $ 1999.

SiOnyx Aurora action cam with color night vision blasts past Kickstarter funding goal

01 May

Kickstarter’s latest major funding success is a campaign for SiOnyx’s Aurora, an action cam said to be the first ever day/night camera of its kind offering “true night vision.” SiOnyx packed a 1-inch sensor into Aurora for low-light capabilities, using it to offer both night vision and color night vision recording options for twilight and night time settings.

Aurora records low-light scenes at 10x the brightness compared to standard CMOS sensors, according to SiOnyx, which claims there are no competing products with Aurora’s level of performance at a sub-$ 800 price point. SiOnyx provides multiple examples of Aurora in action on its YouTube channel, including the video below:

Aurora features a manual Day/Twilight/Night mode selector, as well as time lapse, still picture, and video recording options. The camera has an IP67 waterproof rating for submersion to depths down to 3ft / 1m for up to 30 minutes at a time.

Joining the large 1-inch sensor is an F1.4, 2.0, 5.6 selectable 16mm lens, 8 fps to 60 fps recording, 4x digital zoom, integrated compass/accelerometer/GPS, stereo audio, color/monochrome display, WiFi, a 32GB microSD card for storage and support for both iOS and Android.

SiOnyx has exceeded its $ 50,000 Kickstarter funding goal, so far raising about $ 200,000 with 24 days remaining in the campaign. The company is offering an Aurora Early Bird unit for backers who pledge at least $ 559 USD with shipping expected to start in July 2018, assuming everything goes according to plan. Aurora will have a $ 799 USD MSRP.

Sony: ‘Our company has a vision which is more important than profit alone’

12 Sep

Recently, DPReview was invited to Japan to visit both the Sony headquarters in Tokyo and Sony’s image sensor factory in Kumamoto. The trip was an opportunity to gain some insight into both the philosophy and the technology that underpins the company.

We spoke to both Sony Semiconductor Solutions, the company making the imaging sensors in your cameras and smartphones, and Sony Digital Imaging (DI), the division of Sony Imaging Products and Solutions (SIPS) that makes everything from interchangeable lens cameras (ILCs) to action-cams and camcorders, and lenses. Sony Corporation itself, the umbrella above all these groups, has its hands in a number of sectors – from consumer electronics to smartphones to professional services and motion pictures. Sony Semiconductor, as we previously reported, is its own company, which has some interesting implications we learned about through the course of our conversations.

Be the guinea pig

“The electronics industry is constantly searching for new ideas and there are still many products for us to make. If the guinea pig spirit means developing innovative ideas and embodying them in new products, then I think this is an admirable spirit.” These are the words of Sony co-founder Masaru Ibuka.

At the Kumamoto sensor factory hangs an image of co-founders Ibuka and Akio Morita arm-wrestling in good spirit.

At the Kumamoto sensor factory hangs an image of a golden guinea pig right below a candid of co-founders Ibuka and Akio Morita arm-wrestling in good spirit. On it these words appear, along with one of the principles set out in the Founding Prospectus: “To establish an ideal factory that stresses a spirit of freedom and open-mindedness, and where engineers with sincere motivation can exercise their technological skills to the highest level.”

“If the guinea pig spirit means developing innovative ideas and embodying them in new products, then I think this is an admirable spirit”

More than 70 years later, the ethos of the co-founders still persists in the mindsets of Sony employees. It’s evident in everything from the philosophy of Sony Semiconductor and its relationship with other manufacturers to Sony’s new flagship: the a9.

Planning innovation: Sony a9

Our testing has shown the Sony a9 to be a formidable camera, not just for stills but also video. At Sony, a new camera like the a9 takes two to three years to develop, we were told. Therefore, the photographic technologies the a9 offers had to be planned for years in advance, not long after Sony introduced the world’s first full-frame mirrorless cameras a mere 3.5 years ago. And as we learned during our visit, most of the advancements in the a9 stem from new sensor technologies.

Two to three years ago, how would it have been possible to predict sensor readout speeds that offer autofocus calculations at 60 fps and a fully electronic shutter that is only a stop behind the speed of mechanical shutters? The answer lies in the constant communication between Sony Semiconductor Solutions and Sony DI. And since Sony’s sensor foundry is one of the best in world, providing sensors for everything from cameras and smartphones to security and medical devices, this in-house knowledge and communication is a key advantage.

It takes 2 to 3 years to develop a camera like the Sony a9. Koji Hisamatsu, Mechanical Engineer of the a9, showed us its magnesium alloy body. It offers improved ergonomics and weather resistance over previous models.

Yasufumi Machitani, project leader on the a9, talked to us about the development of the camera. A number of its features, like blackout-free shooting and fast AF/AE calculation, require sensor readout speeds conventionally thought impossible. A stacked BSI-CMOS sensor with integral memory was necessary for these technologies, and the camera division’s awareness of such coming sensor technology years in advance allowed it to plan the a9.

Daisuke Miyakoshi, in charge of the image sensor portion of the product design division, elaborated on this cross-communication: his team is a bridge between Sony Semiconductor Solutions and SIPS (Sony Imaging Products and Solutions), the latter in charge of both product and system design and Sony DI’s parent company. The system design department sends new imager proposals to the product design teams making cameras, and together the teams evaluate success and pain points of actual sensor designs.

This information is then used to send new specification formulations to the image sensor development department at Sony Semiconductor. The communication between these three groups allows fine tuning of both sensor and camera.

Product strategy

Sony’s product strategy is simple. Imagine a pyramid with three customer types: at the top pros, in the middle high amateurs (‘enthusiasts’), and below that consumers. Products are intended to fall within one or span two of these segments.

Sony a7R II | 12-24 F4G @12mm | 1/30s, F4, ISO 5000.

Sony believes there is a growing market of pros and enthusiasts, with shrinking demand at the entry level (it’s hard to argue with that, given the death of the compacts and the rise of the smartphone). This brings a higher demand for better performing products, be it in terms of autofocus, speed, resolution or sensitivity. Therefore, Sony says its product strategy is to pack as much available technology into each product as possible, barring hardware limitations, to meet a certain price point. Machitani-san explicitly told us “there is no intention to limit functions of cameras to certain groups”. In fact, Sony claims it includes many of these functions – where others might remove them in an effort to segment products – just to see what creatives do with them.

It’s a strategy not always taken by other camera manufacturers, but one that makes sense in a post-smartphone era: target customers who want a dramatic step in quality and features from what smartphone imaging offers. It’s not entirely without its issues though. For one, some may find the user interfaces of some Sony cameras overwhelming due to the number of features. Sony is aware of this and constantly iterating – the a9 for example offers an encouraging ergonomic and usability refresh.

Of course, Sony’s own crowded camera lineup can sometimes be at odds with its intended strategy, since Sony is less afraid of cannibalizing itself than other camera companies. Take for instance the short product replacement cycles. Or the almost inevitable focus – since Sony believes in a growing pro and enthusiast market – on full-frame E-mount, which has left the impression among some that Sony is abandoning A-mount1 and APS-C.2 Or the appearance of advanced new technologies in more niche products before they find their way into other product lines. Many of these ‘issues’ stem from the pace of iteration and innovation at which Sony is moving, if not due simply to its relatively newcomer status. But Sony is actively learning, and recent market data suggest its strategy is working.

Vision over profit

You might think that Sony Corporation would like to keep the in-house knowledge of Sony Semiconductor Solutions for its own camera division, but that’s not the case. For one thing, the sales of the semiconductor division to third-parties is a large source of income for the corporation at large, but it goes beyond that.

Although Sony tends to hold its proprietary sensor technology for its own cameras for roughly two years,3 it publicly discloses sensors that are available for sale and their underlying technologies. This allows other manufacturers to integrate Sony sensors into their own products. And this is where it gets interesting: any manufacturer can approach Sony Semiconductor and ask for their own design requirements, often building on Sony’s own sensor advancements that are made public (take full-frame BSI-CMOS or dual-gain for example, two technologies found in the Nikon D850). But if an OEM does so, Sony Semiconductor is not allowed to communicate any intellectual property it gains to Sony’s camera division.

Having this wall (or more accurately, perhaps this two-way mirror) in place makes a lot of sense. After all, OEMs wouldn’t approach Sony about new designs if the sensor division leaked proprietary information to its own camera engineers. So, no folks, Sony’s camera team has not been aware of the Nikon D850’s sensor all along, prepping a response to it years in advance…

There are interesting implications of this wall between Sony Semiconductor and Sony DI: it means that newer, better technologies than those available in Sony’s own cameras may appear in any other manufacturer’s camera, despite using a ‘Sony’ sensor. Indeed, we’ve actually seen multiple examples of this: ISO 64 on the D810 and 16-bit analog-to-digital conversion on the Hasselblad X1D to name just two.

Could this threaten the growth of Sony’s own camera division?

Sony executive round-table. From left to right: Takashi Kondo, Chief Marketing Manager, Hiroshi Sakamoto, Senior General Manager of Marketing, Kenji Tanaka, Global Head of ILCs, and Masanori Kishi, Deputy General Manager of ILC lenses.

When we asked this question, the message from DI executives was clear: “Our focus is to increase the overall market”. Paraphrasing slightly, global head of ILCs Kenji Tanaka said: “Please think about vision. Our company has a vision, which is much more important than profit alone. Of course, if we cut our supply of sensors to other OEMs our camera market share might increase. But this is not our vision. Our vision is to grow the entire imaging market, and Sony alone cannot make every [imaging] product.”

While every manufacturer wants to be number one, no single company can make every product – even within a single sector. It is clear that Sony believes that competition is healthy, and that if Sony sensors help make better products, be it in a Sony device or other OEM device, the consumer wins. And ultimately, that is the purpose of the company.

“Our company has a vision, which is more important than profit alone”

It’s possible that the worst of the camera market collapse is over, but we do wonder whether Sony’s strategy might change if the market continues to shrink. Would the huge current investment in ILCs still pay off? Would sales of class-leading sensors to other OEMs still make sense? The answer from executives was “yes”.

Growing the market

Like every camera manufacturer, Sony wants to grow its market share. But it sees the gain of market share as a secondary effect, almost a byproduct, of growing the market overall. In fact, Sony admitted it doesn’t expect to continue to gain market share simply by getting users to switch systems. Tak Kondo, General Manager at Sony DI, remarked that “the industry is stagnated partly because of a lack of interesting products from camera manufacturers. It’s our obligation to increase the market size.”

We probed Sony about its strategy to move users away from smartphones, arguably the very cause for the declining camera industry. “We want to expand the photo-shooting culture” Tanaka-san told us. “By growing this culture, we hope to stimulate the desire for something [much] better than a smartphone”. Furthermore, Sony chooses to place its focus on mid- to high-end products, which show increased demand. The global decline in the industry is due to a drop in demand for low-end products – both DSLR and mirrorless – thanks to the smartphone.

By making versatile cameras that offer vast benefits over smartphones and more computational photography-oriented devices that widen its user-base, Sony hopes to reverse this trend. That is, grow the market through innovation, a message we’ve heard before.

Why Sony?

Sony believes that it is in a unique position to grow the imaging market. The communication between its image sensor development engineers at Sony Semiconductor and the camera teams at Sony DI give the company a unique advantage: an understanding of important sensor technologies to come two, five, or ten years down the line. The two-way communication between a cutting-edge sensor foundry and camera engineers that need sensor technologies to solve photographic problems is a unique advantage for Sony’s camera division. And Sony’s sensor design and fab group must stay cutting edge simply due to the number of sectors it has its hands in: from smartphones to the medical industry.

Mirrorless cameras are still in their infancy. However, Tanaka-san stressed that when you compare the development speed of mechanical products vs. semiconductor technology, the latter is far faster. Since much of the capability of mirrorless cameras is derived from the image sensor itself, its development speed is much faster than DSLR. So while mirrorless camera technology is a relative newcomer to the field, Sony’s insight into semiconductor advances puts its camera division in a unique position to innovate and iterate quickly, bringing greater speed and functionality to consumer products across shorter refresh cycles.

Will Sony’s ‘guinea pig’ approach pay off? The latest U.S. dollar-based statistics from NPD are certainly encouraging: the first 6 months of 2017 showed a 36% growth in mirrorless camera sales compared to an 11% decline in DSLR sales. In the same period, Sony’s sales of full-frame ILCs grew 42% compared to a decline of 5% for all other manufacturers. It also maintained a #2 position in sales of full-frame ILCs (likely helped by the release of a flagship camera), while growing 26% in mirrorless ILC sales year-on-year. Sony is now at the top in mirrorless ILC sales in the U.S.

While these sales figures are all dollar-based, with many Sony products retailing at relatively high prices, they’re significant – especially when you consider the impact the Kumamoto earthquake must have had on the company.

Challenges

Despite these encouraging figures, Sony’s path will not be a smooth one. Canon and Nikon have been making cameras for a long time and are widely viewed as photography companies, as opposed to consumer electronics companies. Part of the reason the a9 is being targeted so aggressively at pros, and why Sony is working so hard on expanding pro support, is to overcome the perception of the company as a manufacturer of TVs, Walkmans and PlayStations.

At the opposite end of the pyramid, smartphone cameras offer something that most, if not all, standalone cameras to-date lack: convenience of image ingestion, curation and sharing. While Sony PlayMemories apps offer some solutions,4 they leave much to be desired. Thankfully, Sony is well aware of the importance of integrating with cloud services and smartphones.

And then there’s video. Increasingly, cameras that do both stills and video well are more attractive than those that can’t. Sony is on the right track here, offering cameras that are highly capable at both, but there’s still work to be done. The Sony a9 offers some of the sharpest video around thanks to the fact it oversamples a full-frame sensor, yet it lacks a Log profile or an intuitive autofocus interface in video.5

Meanwhile of course, competitors aren’t standing still. Canon’s Dual Pixel AF in video offers a clear user benefit in combining performance and UI/UX. Four Thirds cameras offer 4K video with compelling (mechanical + digital) stabilization. The Panasonic GH5 offers 6K Photo, pre-capture, and effectively simultaneous video and stills capture in its high-resolution anamorphic mode. RED Cinema cameras – albeit in a very different price bracket – can capture at 120 fps for stills extraction or for 24p video.6

But theoretically, these are all challenges that Sony is well placed to face. Sony’s executives see the relationship between Sony Semiconductor and Sony DI as being key to planning for the future, and they assure us that the founders’ spirit of innovation will continue to bring compelling products to the market.


Footnotes:

1 Tanaka-san assured us that ‘the A-mount customer base is small, but loyal, and we need to serve them.’ While Sony does not intend A-mount users to transition to E-mount, it does see the a9 as a potential body for A-mount lenses, via adaption. To that end Sony assures us the disadvantages associated with adapters – like the lack of proper subject tracking – are addressable, though it won’t officially support or offer a solution for Canon lenses natively.

2 Expressing very frank surprise at the idea that some of our readers feel Sony is less committed to APS-C, Sony DI executives assured us that, on the contrary, they are fully committed to APS-C. They pointed in particular to its potential to increase business by its adoption as a second camera for pros (a6300/6500) or a first-time camera for casual users (a5100/6000).

3 While we weren’t explicitly told this, one might surmise it from the fact that the sensor in the a7R II has not appeared in any other manufacturer’s camera since its launch over 2 years ago.

4 For example, ‘Sync to Smartphone’ ensures all my JPEGs from my a7R II end up on Google Photos via my Google Pixel in full resolution original quality without me moving a finger.

5 We asked Sony about the omission of S-Log2 and PlayMemories on the a9. We suggested it ostensibly appeared like forced product segmentation, uncharacteristic of Sony’s product strategy. While it still appears that may indeed have been the case, we were assured that Sony takes our negative feedback about these omissions seriously.

6 Some RED cinema cameras are capable of assembling 24p footage from 120p capture by frame averaging, which removes the stutter that would otherwise result from the higher shutter speeds you’d likely shoot 120p footage at. It’s quite clever.

Nikon celebrates 100th anniversary with new vision and crazy music video

26 Jul

Today is Nikon’s 100th anniversary. Founded on this day in 1917 as Nippon Kogaku K.K., the Nikon Corporation has transformed from a manufacturer of precision optical glass into one of the most iconic photographic brands in the world. Their camera legacy began in 1948 with the Nikon Model I and continues on to this day. And regardless of your opinion of Nikon today, the past 100 years are certainly worth celebrating.

The festivities has been going on all year, with videos, a dedicated website, a series of special edition products, posters paying tribute to the company’s most iconic cameras and a lot more, all released this year under the “100th Anniversary” seal.

But today is THE day, and in addition to teasing the upcoming D850 DSLR Nikon has released an official statement from its president about the future of the company, posted a couple of tribute videos, and released one of the wackiest music videos you’ve ever seen.

Tribute Videos

The music video in question was posted to the Nikon Anniversary website, and it’s an “anniversary dance movie featuring Nikon employees and a new generation Japanese rock band, Mrs. Green Apple!” Take a look for yourself:

But Nikon didn’t stop there. We also found this tribute to the F-Mount:

And this charming video titled “Passage of Light”, which pays tribute to the Nikon family.

The Future of Nikon

Finally, on a more serious note, the company published an official press release alongside a personal message from president Kazuo Ushida.

You can read the full press release and statement below, but the most intriguing bit is the part where Mr. Ushida lays out the company’s vision for the next 100 years. “The difference from our past strategies is that we will offer not only products, but also ideas and solutions as well,” says Ushida. “Nikon will be reborn as a solution company providing superior technologies and ideas, holding ‘light’ as our core competency.”

The Nikon vision moving forward is summed up in a single phrase: unlock the future with the power of light. We’ll just have to wait and see what they means in practical terms, but we can only hope the next 100 years are as innovative and groundbreaking as the last hundred.

Happy Birthday Nikon.

Sony 1000 fps sensor gives high-speed vision to industrial robots

23 Jul

Sony is the global market leader in the image sensor field, producing imager chips not only for cameras and smartphones but also for industrial applications. Now, one of the features that we first saw in a Sony smartphone camera has made its way into a newly announced sensor meant for use with robots in manufacturing.

The Sony 1/3.02″ IMX382 sensor allows industrial robots to detect and track objects at 1,000 frames per second, which could result in autonomous machines that can react to an object’s movements or other changes in their environment in real time.

The sensor not only captures images at high speed, it’s also capable of processing them and sending information to the machine it is attached—no computer or other additional processing unit is required. In the video below, you can see how the technology is used to identify different currencies at high speed, track several objects at the same time and visually inspect items without a need to slow-down a conveyor belt or production line.

The Sony IMX382 will be available to potential customers very soon, with sample shipping envisaged for October 2017.

Beyond Human Vision – Seeing More With Photography

20 May

Have you ever been frustrated because you don’t seem to be able to photograph a scene the way it looks to you, with your vision? Maybe you can’t get a sharp image even though the scene is perfectly clear, or perhaps the camera fails to capture the beautiful variety of light in a landscape.

It’s possible that you’re having technical trouble in getting the most from your camera, but it might also be because the human eye and the camera aren’t the same, despite their compelling similarities. For instance, our eyes have a much broader dynamic range than any sensor or film, and our binocular vision gives us amazing depth perception.

But have you ever thought of the ways in which cameras can outperform the vision of your eyes? These aspects of your favorite tool are not obscure quirks, but commonly used techniques that broaden your perception of the world around you.

So let’s dive into the mysteries of the camera! Maybe realizing how photography expands your worldview will make you look at photography (and reality) in a slightly different way.

1. Capturing time

With the camera, you can capture time in different units than your eye does. This, of course, is done by choosing a shutter speed. There isn’t a direct counterpart to shutter speed in human vision, but that doesn’t mean we can’t take advantage of the camera’s ability to observe the passage of time beyond our own vision.

Beyond vision 01

A long shutter speed of several seconds lets you see movement that isn’t discernible at all or in the same way by vision alone. Exposure: 1/3rd of a second, f/14.0, ISO 100.

Beyond vision 02

Controlling shutter speed is also what makes light painting possible. Exposure: 134 seconds, f/5.6, ISO 100.

Beyond vision 03

Using a really fast shutter speed lets you transform continuous motion that you see as a blur into a frozen instant. I thought I was photographing a bird sitting on a snowy branch, but all I got was a miniature snow flurry. Exposure: 1/500th, f/2.8, ISO 800.

2. Capturing light

Even though your eyes are better than cameras at distinguishing a wide range of light levels in the same frame, the camera can extend your observation of very dark and very light scenes. You can accomplish this by carefully balancing shutter speed, aperture, and ISO. Modern cameras allow for ever higher ISO levels, which increase the light sensitivity and allow you to capture images in really dark scenes.

Beyond vision 04

If you’re lucky, you can see The Milky Way with your naked eye. Capturing it with a camera, though, allows you to see even more details of our galaxy. Exposure: 35 seconds, f/4.0, ISO 1600.

3. Field of view

The human field of view is static, about 190 degrees depending on the anatomy of your face. By using lenses, you can vary that field of view from slightly larger to much smaller.

Beyond vision 05

A wide field of view, but still not as wide as that of most humans. Exposure: 1/13th, f/7.1, ISO 400.

Beyond vision 06

A very small (narrow) field of view. This close-up, or macro, shows the tiny details of a fungus growing. Exposure: 1/25th, f/6.3, ISO 100.

4. Depth of field

Although you can’t control it, your eyes do have a changeable aperture called the pupil. It’s difficult to find information on exactly what kind of apertures the human eye can pull off. But whether the camera can do more or less, the effects of a small or large depth of field differ between eyes and cameras.

Examples of this are bokeh, which is achieved by a large aperture (small depth of field), and the starburst effects caused by a very small aperture (large depth of field).

Beyond vision 07

Snow and ice crystals creating bokeh. Exposure: 1/100th, f/4.0, ISO 160.

Beyond vision 08

Starburst over a snowy sea. Exposure: 1/500th, f/20.0, ISO 100.

5. Color

Although cameras have been designed to capture the same colors that we see, some can detect color in a very different way, including sensors used mainly by scientists to detect ultra-violet, infrared, or other parts of the non-visible spectrum.

The ability of some film to capture black and white offers us a new way to see the world, focusing on tones rather than colors. You can also make black and white photographs with a digital camera, though this is almost always a conversion from color to monochrome, either in-camera or in post-processing (there are a couple of monochrome digital cameras available on the market, but they are neither common nor cheap).

Beyond vision 09

A monochrome vision – this photo was taken as a color image, then converted to black and white in post-processing. Exposure: 1/80th, f/4.0, ISO 1250.

Conclusion

Can you come up with more things that the camera can do but you can’t? Do you think your camera helps extend your vision – both literally and metaphorically? I’d love to hear from you and see some of your creations in the comments section below.

Sony releases machine vision sensor capable of 1000 fps object tracking

17 May

Sony has released a new machine vision CMOS sensor, and though it’s destined for assembly lines and robots, it’s still interesting to us. Like the chip in the RX100 V, the IMX382 is a stacked, backside-illuminated chip capable of 1000 fps imaging. And, like that sensor, its stacked design includes signal processing circuitry in the chip. Unlike the RX100 V’s sensor, though, the 1.27MP IMX382 conducts video processing and subject recognition in parallel, so that it outputs both a ‘viewing’ stream and a ‘sensing’ stream simultaneously.

The sensing processing uses color and brightness information obtained from the sensor, enabling incredibly fast subject identification and tracking at 1000 fps. You can see what that looks like in the video below:

At a little over 1 megapixel this sensor is not destined for a smartphone or camera. And of course those applications get more complicated since they also have to re-focus a lens to keep up with a moving subject, but it’s interesting to see what levels of recognition and tracking possible when you bring signal processing to the chip itself.

This CMOS sensor with 3D-printed microlenses is designed to mimic predator vision

23 Feb

A research team at the University of Stuttgart, Germany has proposed utlizing a 3D printer with ultra-short pulse laser-technology to print multi-component microlenses directly onto the surface of a CMOS image sensor. Doing so would create a ‘foveated’ imaging system: one with greater resolving power in the center, similar to the vision of predators in the animal kingdom.

In the research project, lens groups consisting of one of four types of tiny doublet lenses were printed directly onto the chip, after some functional layers like the existing microlenses and the color filters had been scratched off. The individual lenses come with 35mm equivalent focal lengths of 31, 38, 60 and 123mm which together give the system a field of view of approximately 70 degrees but with extra resolution at the center.

The footprint of the optics on the sensor is less than 300 x 300µm and the height of the lenses is 200µm, allowing for the design of highly miniaturized cameras that could be used in areas such as endoscopy, optical scientific instruments, optical sensing, camera drones or security.

Improvements to the current version could include anti-reflective coatings on the lenses, the use of triplets or more lens elements for aberration correction and the inclusion of absorbing aperture stops.

The paper by Simon Thiele, Kathrin Arzenbacher, Timo Gissibl, Harald Giessen, and Alois M. Herkommeris is titled ‘3D-printed eagle eye: Compound microlens system for foveated imaging’ and can be read in its entirety on Science Advances. 

Abstract:

We present a highly miniaturized camera, mimicking the natural vision of predators, by 3D-printing different multilens objectives directly onto a complementary metal-oxide semiconductor (CMOS) image sensor. Our system combines four printed doublet lenses with different focal lengths (equivalent to f = 31 to 123 mm for a 35-mm film) in a 2 × 2 arrangement to achieve a full field of view of 70° with an increasing angular resolution of up to 2 cycles/deg field of view in the center of the image. The footprint of the optics on the chip is below 300  × 300 um, whereas their height is less than 200 um. Because the four lenses are printed in one single step without the necessity for any further assembling or alignment, this approach allows for fast design iterations and can lead to a plethora of different miniaturized multiaperture imaging systems with applications in fields such as endoscopy, optical metrology, optical sensing, surveillance drones, or security.
