Olloclip announces Multi-Device Clip for smartphone lenses

05 Sep

Olloclip has built a reputation as one of the most successful manufacturers of smartphone accessory lenses. However, so far most Olloclip lenses have had one important limitation: they were device-specific. If you had more than one smartphone you could not use the lenses with all your devices, or if you upgraded to a new handset you usually needed to get new lens clips and/or lenses.

This is now a thing of the past, however. Today Olloclip has announced its new Multi-Device Clip. The clip is designed to work with the company’s Connect X line of interchangeable lenses, which includes several wide-angle options, macro lenses, a telephoto and a fisheye, and works with most smartphones.

The Multi-Device-Clip can expand to fit devices of up to 12mm thickness, meaning it is compatible with screen protectors and you can usually leave your case on as well, when snapping an image with your Olloclip lenses.

Olloclip’s new Multi-Device Clip will be available with any of the Connect X lenses mid-September starting at $ 60. You can sign up for more information on the upcoming release on the Olloclip website.

Sony launches the Xperia XZ3 high-end smartphone

31 Aug

Sticking to its usual 6 months cycle, Sony has launched a new model in its high-end XZ smartphone line. The Xperia XZ3 follows on from the XZ2 which was released earlier this year. The new device is more evolution than revolution and the major differences to the XZ2 are an updated screen, a bigger battery and a slightly modified body design.

The new 6-inch OLED display supports HDR and comes with a 2880 x 1440 pixel resolution. It is protected by Gorilla Glass 5 that is curved at the edges to integrate smoothly with the aluminum body. The bezel dimensions have also been reduced, allowing for an improved display/body ratio.

Probably thanks to the marginally larger device body Sony has been able to use a beefier 3330 mAh battery which, compared to the XZ2’s 3180 mAh unit, should deliver a slightly improved battery life. Sony has also improved the S-Force front speakers, offering better base and treble as well as a 20% increased overall volume.

At 1/2.3″ the sensor is comparatively large for a smartphone camera and is combined with a 25mm equivalent wideangle lens and F2.0 aperture

Other specs include a Snapdragon 845 processor, 4GB of RAM and 64GB of storage, all wrapped up in a IP68 water and dust resistant body. At least on paper the rear camera specification has not changed for the new model and the XZ3 comes with the same 19MP camera module as the XZ2. At 1/2.3″ the sensor is comparatively large for a smartphone camera and is combined with a 25mm equivalent wideangle lens and F2.0 aperture. Predictive PDAF, laser AF and 4K video recording are on board as well.

The front-facing unit has been updated, however, and now comes with a higher 13MP resolution and faster F1.9 lens. The Xperia XZ3 will b available from October 17 for $ 900. More information is available on the Sony Mobile Blog.

Smartphone image sensors are low in supply

21 Aug

In May we reported that CMOS sensor sales were at an all time high and record numbers were expected for 2018.

It appears the strong sales have not slowed down at all over the summer, and we’re now in a situation where CMOS sensors are in short supply. Industry news publication IFNews quotes a number of Chinese sources that refer to an article in the Taiwan Economic Times, reporting that image sensors are now in short supply.

Big suppliers like Sony and Omnivision are increasing their prices for image sensors

This is largely due to dual and triple cameras becoming more commonplace on smartphones, with even mid-range models often featuring dual-setups now, sometimes at front and back.

As a result big suppliers like Sony and Omnivision are increasing their prices for image sensors. Smaller smartphone manufacturers who don’t get the same priority access to the big suppliers as major manufacturers are diverting orders to smaller sensor makers, such as Pixart and Silicon Optronics (SOI) to keep component cost under control.

The trend for multiple cameras and sensors on smartphones is unlikely to stop any time soon, so be prepared for increased sensor prices having a minor knock-on effect on final device retail pricing. On the plus side, as this development mainly affects the smaller sensor implemented in smartphone cameras, the impact on the market for the larger units used in DLSRs and most mirrorless system cameras should be minimal.

Huawei caught trying to pass off DSLR images as smartphone photos…again

20 Aug

It appears Huawei hasn’t learned its lesson. Two years after the Chinese smartphone manufacturer was busted for trying to pass off a DSLR image as a photograph captured with its P9 smartphone, it’s under scrutiny yet again.

Huawei is now taking heat over a recent advertisement for its Nova 3 and 3i smartphones, wherein Huawei insinuates certain photos were captured with a smartphone when a behind-the-scenes photo proves that’s not the case.

The video, which is 30 seconds long, shows various scenes in which the subjects snap photos using various built-in camera features, including beauty, HDR and AI modes. Although the video never explicitly states the images were captured with a Huawei smartphone, it’s very much implied that’s the case.

A critical eye would instantly realize the images weren’t captured with the phone. But for the sake of empirical evidence, we’ll reference the above image uploaded to Instagram (and subsequently deleted) by Sarah Elshamy, the actress in the ad. In the behind-the-scenes still, pictured above, it’s clear the main actor was holding his hand out to make it appear as though he’s holding a phone, when in reality the scene was being shot with a Canon DSLR.

Again, Huawei never specifically mentions what the ad was shot with, leaving a bit of room for leniency. But it’s misleading at best, and downright false advertising at worst. We’ve reached out to Huawei for an official comment and will update this article accordingly if we hear back.

OKO is an immersive viewfinder for your smartphone camera

02 Aug

There’s an abundance of smartphone camera accessories available but until now we’ve been missing one item: a viewfinder. Thanks to the OKO crowdfunding project on Kickstarter this gap might soon be filled, however.

The OKO is designed to do pretty much the same things as a conventional viewfinder. It blocks screen reflections, offering an immersive and undistracted view of the scene and allowing for a more stable shooting stance when holding it up to your face. Its design is far from conventional, however.

The OKO resembles a VR-headset and is compatible with most 4.7″ and larger smartphones. The mobile device is inserted at the front and in the bottom there is a fairly large hole, allowing you to control the camera on the touch screen of your phone (but probably also letting some light in).

In front of the phone screen two 6x magnifying oculars provide a view that should be much closer to the real scene than what your smartphone display alone can provide and many photographers might find that using two eyes to frame your shots is more comfortable than just using one, like with a traditional camera viewfinder.

The OKO’s major downside is pretty obvious: you’ll look pretty ridiculous wearing the thing on your head while hunting for photo opportunities. For some this might be a small price to pay for the perfect shot, however.

If you fall into that latter group, you can now pledge between $ 39 for the early bird basic kit and $ 160 for a full-blown package including 4 accessory lenses. At the time of writing the project has almost reached its funding goal with 56 more days to go, so there’s a good chance the project will go ahead. Shipping is expected in March 2019.

Watch the video below for more information or head straight to the OKO Kickstarter page.

Equipment List for Making Better Smartphone Videos

01 Aug

In case you haven’t noticed, smartphone cameras keep getting better and better. Not only do they take better still photos, but they also record high-quality video. Many latest generation smartphones are equipped with image stabilization, focus tracking, and the ability to shoot in 4K.

Smartphone video accessories 03

This is especially notable with the recent release of IGTV and social media platforms encouraging more video creation. With that in mind, it’s worth investigating how to use your smartphone to take better smartphone videos. As usual, it comes down to the tools you use. Here are several accessories worth investing in to take your smartphone videography to the next level.

A Way to Secure Your Phone

Equipment List for Making Better Videos With Your Smartphone - image on a cell phone

Smartphones today are being built tougher, but they still have a sleek body that makes them easy to drop. To keep your phone more secure, consider getting one of these accessories. This will help you take sharper and better videos.

Pop Socket

In case you’re not already hip to the Pop Socket, here’s why they’re so popular.

These little devices look deceptively simple. They’re just a plastic backing that sticks to your phone and pops out to give you a better grip. This helps you hold your phone with one hand while taking selfies or shooting tricky angles. They are especially helpful while shooting video.

But there are some problems with the Pop Socket. For one thing, they’re bulky. Even when retracted, the Pop Socket sticks out just enough to make it a hassle to stick your phone in your pocket or put it into your car’s cell phone holder.

Secondly, Pop Sockets look about as cheap as they cost, at least in my opinion. This can ruin the aesthetic of the pricey phone you’ve invested in. Finally, these suckers are pretty permanent. Once they’re attached to your phone, they’re useless if you remove them. For that reason, I prefer using the next accessory to keep my phone secure.

Black Rapid WandeR Bundle

Black Rapid is known for their camera straps, but they also have a cool new product for smartphones. The WandeR Bundle is a nylon tether wrist strap that attaches to your smartphone’s case (above).

You can also use the included TetheR-Clip to secure your phone to a bag or camera strap (see below). It’s a simple concept that is very well executed and will make it hard to drop or lose your phone again.

A Smartphone Tripod

Like any other camera, there’s a time and a place to use a tripod with a smartphone, especially when creating videos. The good news is that you don’t need a giant tripod for your smartphone, although you can certainly adapt any basic tripod for use with a cell phone using an adapter (more on that below).

But if you want a more compact setup, consider getting a dedicated smartphone tripod. The Manfrotto PIXI EVO  is a popular option, as is the JOBY GorillaPod Hybrid Mini. Both are small, yet sturdy enough to hold a smartphone or even a small mirrorless camera if needed.

No matter what kind of tripod you end up with, make sure you get a cell phone tripod adapter to properly mount your device.

External microphone

Most smartphones have pretty good built-in audio recording features. But sometimes you need an enhanced audio solution. Note that for both of these microphones, you may need a smartphone audio jack adapter if you have a phone without a traditional audio jack.

One of the best smartphone microphones out there is the Rode VideoMic Me microphone. It’s very compact and comes with a fluffy windscreen (also known as dead cat). To use it, simply plug it into your smartphone’s audio jack. It worked well with my Samsung Galaxy S8 but didn’t work at all with the Google Pixel.

The reason is the location of the audio jack. On the S8, it’s located on the bottom of the phone, on the opposite end of the cameras. The Pixel’s audio jack is located on top, next to the camera. Thus, the microphone was in the shot both with and without the windscreen. So check the audio jack’s proximity to your camera before investing in this mic.

Another type of microphone you may need is a lavalier (or lapel) mic. It is placed in close proximity to the speaker’s mouth to isolate their voice from environmental noise. Lavalier mics are generally wired, meaning they can be difficult to use when plugged directly into your video recording device.

So the most convenient setup is to record your visuals with one camera, and record audio with a lavalier mic plugged into a smartphone. You’ll need an audio recording app to do this. A top of the line lav mic option is the Rode smartLav+, or the more affordable Stony-Edge Simple Lav. Note that sound quality typically corresponds with price, but it truly depends on your budget.

Smartphone gimbal

Many smartphones come with built-in stabilization that will help minimize or remove shake from your videos. However, you still need an extra tool if you want buttery smooth, cinematic video footage. The simplest video stabilization tool is an electronic handheld gimbal.

There are two main gimbals out there worth considering, and they’re very competitive in terms of features and price. One is the DJI Osmo Mobile 2, and the other is the Zhiyun Smooth Q. I’ve been using the Smooth Q for the past few months and have been blown away by how much my smartphone video quality has improved.

Best of all, a gimbal is easy to use and quite affordable for the features it offers.

Extra Power

While smartphone battery life keeps gradually improving, it’s still a good idea to bring a portable cell phone charger with you.

There are tons of external batteries on the market, but Anker is by far one of the more reputable brands. In particular, the Anker PowerCore 10000 is a compact, efficient, external battery. It can charge either your smartphone or electronic gimbal or both at the same time. Just be sure to charge the battery ahead of time and bring the right cables.

Over to You

In short, you don’t need a lot of tools to start using your smartphone to make better videos. However, if you add these tools to your kit, you’ll be well on your way to producing more professional-looking videos.

Apple patents correction system for smartphone accessory lenses

26 Jul

Accessory lenses for smartphones can be useful tools for expanding the photographic capabilities of your device. However, the process of physically attaching these lenses to the smartphone and centering them above the camera lens is prone to minor but important error as even a slight misalignment can result in a drop in image quality. Additionally, the accessory lens’ optical design can have a detrimental effect on the image output.

Apple has now been granted a patent that aims to fix the problem using a two-pronged approach: by using correction software and a movable built-in camera lens.

The document describes camera hardware and an analysis and processing software that can be used to analyze image quality and detect problems potentially caused by add-on lenses. By looking at certain image metrics, the system could compare image quality before and after attaching an accessory lens and then use software algorithms to correct accordingly.

Additionally, actuators would allow to change the position of the built-in camera lens on multiple axes, in order to correct for any misalignment of the accessory lens. This could include tilting the camera and varying the distance between the built-in lens and accessory lens.

The patent suggests electronics, magnets and radio sensing among other methods to detect if an accessory lens has been attached. If the smartphone knows what exact accessory is being used, additional options in the camera app could be utilized as well.

As usual, there is no way of knowing if and when this system will make it into a production device but it certainly looks like it could make the use of accessory lenses more appealing to many of us.

You can find the complete patent document on the USPTO website.

Sony IMX586 smartphone sensor comes with 48MP and Quad Bayer design

24 Jul

Sony has introduced a new smartphone image sensor today and, looking at the IMX586’s impressive spec sheet, the new chip could help boost smartphone camera performance further in the next generation of high-end devices.

The sensor combines two key technologies: very high resolution and a ‘Quad Bayer’ color filter pattern to offer a series of clever processing modes.

According to Sony, low light performance is comparable to large 1.6?m pixels

With its 1/2″ format (6.4 x 4.8 mm) the stacked sensor is at the large end of the spectrum for smartphone cameras: nearly twice the size of a typical 1/3″-type chip. This allows it to squeeze 48MP onto its surface, but still requites a comparatively small pixel size of 0.8 ?m.

The IMX586 is not just about pixel count, however. It comes with a Quad Bayer color filter array in which every 2×2 pixel array has the same color filter. This allows it to offer several ways to process its data, depending on the conditions.

In low light image data from the four pixels in such an array is merged and processed as one single pixel, resulting in a reduced 12MP image resolution. According to Sony, low light performance is comparable to large 1.6?m pixels.

In bright light the image signal processor can make full use of the sensor’s 48MP pixel count, however, and capture high-resolution images or use the abundance of captured image data for high-quality digital zooming. This requires processing to convert the ‘Quad Bayer’ data into an approximation of what a 48MP Bayer sensor would have captured. It’ll be interesting to see how well this does.

Sony’s write-up seems to allude to a third way of using the data. It talks about the sensor being able to display up to four times the dynamic range of conventional products. We suspect this uses the system Sony uses on its IMX294 chip, where alternate pixels are switched off, mid exposure, protecting highlight capture while still recording full shadow detail. The Quad Bayer pattern would lend itself particularly well to this.

This three-mode approach… may remind some readers of Fujifilm’s Super CCD EXR technology

This three-mode approach to offering better performance in low light, higher DR in high contrast situations or high resolution when there’s plenty of light may remind some readers of Fujifilm’s Super CCD EXR technology, with which there are some obvious parallels.

As usual we don’t know when the new sensor will see the light of day in a production smartphone, but the Sony Xperia XZ3 which is expected to be launched at IFA in September looks like a good candidate. Given Sony is the biggest sensor provider to the smartphone industry we should sooner or later see the IMX586 in non-Sony smartphones as well.
