DJI has launched the Zenmuse X7, a Raw video capable Super 35 camera module. The camera/gimbal system which mounts to the company’s drones features a new, proprietary lens mount.

The camera can shoot 6K CinemaDNG Raw or 5.2K Apple ProRes footage at up to 30p or 3.9K CinemaDNG and 2.7K ProRes at up to 59.94p. The company claims 14 stops of dynamic range but, like all video manufacturers, doesn’t specify how this is assessed.

It uses the new “DJI Cinema Color System” based around a D-Log Curve and D-Gamut RGB color space.

The camera includes two exposure modes, one that varies amplification gain and an “EI” mode that always uses minimal amplification (~base ISO) with metadata tags to denote the intended final brightness, to preserve DR. This is increasingly common practice in the video sphere but has yet to make its way across to stills photography.

The previous model (the Zenmuse X5) was based around a Micro Four Thirds mount and came with a distinctly Panasonic-like 15mm F1.7 lens. Instead the Zenmuse X7 is based around the company’s own ‘DL’ mount.

Alongside the camera, the company is releasing 16mm, 24mm, 35mm and 50mm F2.8 lenses, the longest three of which will include mechanical shutters. The carbon fiber bodied lenses will cost $ 1,299 each, with the exception of the 50mm, which is $ 100 cheaper, though a camera bundled with all four lenses will cost just $ 4,299.

The camera on its own will cost around $ 2699 and will be available from November.

Press Release:

DJI Reveals Zenmuse X7, The World’s First Super 35 Digital Film Camera Optimized for Professional Aerial Cinematography

October 11, 2017 – DJI, the world’s leader in civilian drones and aerial imaging technology, today introduced the Zenmuse X7, the world’s first Super 35 digital film camera optimized for professional aerial cinematography. Designed to work seamlessly with the DJI Inspire 2 drone, the Zenmuse X7 delivers superior image quality, interchangeable lenses, and a new DJI Cinema Color System for post-production to give film and video professionals more creative freedom.

“The Zenmuse X7 offers everything professional content creators need to make their aerial footage as stunning and vivid as they demand,” said Paul Pan, Senior Product Manager at DJI. “From the large Super 35 sensor to a new mount, lenses, and color system, the Zenmuse X7 gives cinematographers and professional photographers an unmatched set of tools that work seamlessly with the DJI Inspire 2 drone to capture high-quality footage that is easily integrated into projects shot with industry-leading handheld cameras.”

Greater Expressive Freedom

The Zenmuse X7 is equipped with a Super 35 video sensor featuring 14 stops of dynamic range for more detail in low-light conditions. Its low-noise image capture enhances grading flexibility by preserving details in both highlight and dark areas while enabling a shallow cinematic depth of field.

To meet the rigorous requirements of filmmakers and television production professionals, the Zenmuse X7 captures the highest image resolutions ever for an integrated drone camera. It is capable of shooting 6K CinemaDNG RAW or 5.2K Apple ProRes at up to 30 FPS, as well as 3.9K CinemaDNG RAW or 2.7K ProRes at up to 59.94 FPS to integrate seamlessly into industry-standard post-production workflows.

Enhanced Imaging Potential

The Zenmuse X7 uses a dedicated aerial mount system, the DJI DL-Mount, featuring an ultra-short flange focal distance to carry prime lenses optimally. Available with focal lengths of 16 mm, 24 mm, 35 mm, and 50 mm, each lens has a maximum aperture of F/2.8 and is crafted out of carbon fiber, making them durable and lightweight for high-performance aerial cinematography with the DJI Inspire 2 drone.

To allow for advanced setting adjustment and fine-tuning, the 16mm lens is equipped with a built-in ND 4 filter, and the 24 mm, 35 mm, and 50 mm lenses feature a mechanical shutter.

Higher Flexibility in Post-Production

DJI has also introduced a new DJI Cinema Color System (DCCS) making the Zenmuse X7 an asset on every film set for movies, TV series, commercials, documentaries, and more.

“For the Zenmuse X7, we took our color science to the next level,” continued Pan. “We consulted the world leading authorities in color science, Technicolor. With their guidance, our engineers developed an optimized gamma curve for the X7 allowing more latitude without sacrificing image quality.”

DCCS features a new D-Log Curve and D-Gamut RGB color space to give more flexibility and color options during the post-production process. The D-Log further extends the dynamic range, while the D-Gamut RGB color space preserves more color information to support the most demanding filmmaking scenarios, providing accurate color for quick and easy post-processing.

The new EI Mode mimics the way a film camera works to help cinematographers capture as much information as possible in every scene while balancing the dynamic range and noise with different log curves for more flexibility during the post-production process.

The Zenmuse X7 gimbal system weighs just 631 grams with the 16 mm lens. The DJI Inspire 2 has a flight time of up to 23 minutes with the Zenmuse X7. For more info about the Zenmuse X7, visit www.dji.com/zenmuse-x7.

Price and Availability

The Zenmuse X7 camera is priced at $ 2,699 USD. The 16 mm, 24 mm and 35 mm lenses will be available for $ 1,299 each, and the 50 mm for $ 1,199. Customers can purchase the Zenmuse X7 prime lens combo including all 4 lenses for $ 4,299. The Zenmuse X7 will start shipping in early November 2017 from store.dji.com, in DJI Flagship Stores and through DJI Authorized Dealers worldwide.

DJI Care Refresh will be available for the Zenmuse X7 camera gimbal system as well as for the Inspire 2 drone. For more info, visit www.dji.com/service/djicare-refresh.

Nissin announces Super Light Stand LC-50c: The world’s lightest light stand

15 Sep

Nissin has released a new light stand that it claims is the lightest in the world. The Super Light Stand LS-50C uses carbon fibre for its central column to keep its total weight down to just 575g/1.2lb. But even at that featherweight, it can still hold 1.5kg/3.3lb and extends to a maximum height of 200cm/79in.

Packed away, it stores at a minimum length of 48.5cm/19in.

As these stands are generally static, the idea of using carbon fibre to make them lightweight is mainly to reduce the weight of the photographer’s kit when traveling, but also to make assistant’s work a little easier—whether carrying to and from a shoot, or holding during one.

The centre column uses a collar-style rotary locking mechanism more often seen on tripods, which the company says makes tightening easier and more effective than standard locking nuts and handles. Nissin has also come up with an interesting design for the leg clamps that allows them to be extended to a flat position on the ground for added stability.

The Nissin LS-50C will go in sale in the next couple of days priced 13,500 yen plus tax (approx. $ 130). For more information see this translated version of the Nissin product page.

DIY: How I built my own super macro rig for less than $250

14 Sep

Last year I bought a macro lens for the summer—just a normal one with 1x magnification—and I immediately found myself in a beautiful and mesmerizing world of minuscule flowers and bugs. I found that in macro photography, you don’t have to travel to beautiful places to take beautiful photos—you can just walk around in your backyard, and discover a whole new world. Also, you don’t have to wake up at 4 AM to catch the golden hour…

This year, however, I decided I wanted to take things to the next level. I wanted a super macro lens with 2x or more in magnification, so that I could take closeup portraits of ants and bees. I started Googling around for the right lenses and soon discovered that there are only a couple of them out there. The best known is the Canon MP-E 65, but it costs north of $ 1,000. There is also a 2x macro lens from Venus Optics, but it’s still $ 400 for the lens alone… and then you need to add some kind of flash setup.

I thought this was way too much money to just try super macro photography, so I decided to look around for cheaper solutions.

That was when I discovered this excellent article on a Swedish site. It describes how you can build your own super macro rig with cheap parts off Amazon or eBay. This build works with any Canon EF compatible camera, meaning most Canon cameras and also mirrorless cameras with adapters. After some browsing, I was able to find all the parts on Amazon and I ordered them.

The rig is based around the Canon 40mm f2.8 STM lens. This lens is excellent for this purpose as it is very cheap, small, light, sharp and has beautiful bokeh (possibly more beautiful than the Canon MP-E 65). For this particular setup, the lens is mounted reversed to get more magnification using a Meike reverse adapter. The adapter, in turn, has a cable that allows you to keep control over aperture despite having the lens reversed.

You will need a 52-58 mm step-up ring to fit the Canon 40mm with the Meike reverse adapter. Then, if you put an extension tube before the Meike adapter, you have a super macro lens! Just add more extension tubes for more magnification.

I have found that 36mm of extension tube is my sweet spot—it gives me 2.3x magnification, meaning that the subject will be 2.3x bigger on the sensor than it is in real life. So a bug that is 10mm tall will cover all 24mm of a full frame sensor.

The rest of the parts are the flash and parts needed to mount it in a way that puts it as close to the subject as possible. You should also try to make some kind of diffuser, as shown in the video.

All essential parts:

  • Canon EF 40mm f/2.8 STM Pancake Lens (around $ 50 used)
  • Meike reverse adapter (around $ 55)
  • Meike MK-300 Flash (around $ 33)
  • Vello CB-600 Straight Flash Bracket (around $ 10)
  • Articulating arm, 7” (around $ 14)
  • Fotga Extension tubes for Canon EF (around $ 40)
  • Vello TTL-Off-Camera Flash Cord for Canon EOS 0.5 m (around $ 20)
  • Goja 52-58MM Step-Up Adapter Ring (around $ 8)

In total (if you buy the Canon lens used): $ 230 USD

See the video up top for detailed instructions, and scroll down to see some sample photos. The parts can be put together in a few minutes, as shown in the video.

Lastly, a small tip for shooting super macro insect shots with this rig: use a slow shutter speed, such as 1/40s. That way you will get a lot of color and light in your photo, making it more interesting and beautiful. Don’t worry about sharpness, the flash is a lot faster than 1/40, and it will make sure to freeze your subject in most situations.

Playing a Super Mario Bros. level with Hololens is the best case for AR we’ve seen

23 Jun

Developer Abhishek Singh makes a compelling case for wearing a headset and looking silly – he created an augmented reality Super Mario Bros. level and played through it in New York’s Central Park. Oh, and he dressed as Mario for the demo video below, which is the best thing ever.

Singh tells Upload VR that he had to re-think some of the game elements to make it playable on a human scale – Mario can jump much higher than any plumber we know. Of course, there would be some obvious challenges bringing a game like this to the masses. But we’ve got our fingers crossed for a future of virtual reality includes life-size Koopas and gold coins.

Panasonic AU-EVA1 offers EF-mount Super 35 5.7K capture to SD with Raw promised

03 Jun

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_3267204641″,”galleryId”:”3267204641″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Panasonic has announced a 5.7K Super 35 format cinema camera that sits between the GH5 and the VariCam LT 4K. The camera is built around a Canon EF mount and can capture 4K video at up to 10-bit 4:2:2 quality to SD cards.

Panasonic hasn’t discussed revealed detailed specs yet but says the camera will have ‘dual native ISOs,’ which is usually videographer speak for sensors with a dual gain design.

The camera has XLR audio inputs and both HDMI and SDI video outputs. Initially it will output 4K over these connectors but Panasonic promises 5.7K Raw output to external recorders with a firmware update. The camera will ship in ‘the autumn’ at a cost of around €8000.

Press Release:

Panasonic has previewed the AU-EVA1, at Cine Gear Expo 2017 in Los Angeles, USA, a new 5.7K cinema camera positioned between the Panasonic Lumix GH5 4K mirrorless camera and the VariCam LT 4K cinema camera. Compact and lightweight, the AU-EVA1 is tailor-made for handheld shooting, but also well suited for documentaries, commercials, and music videos.

“For cinema-style acquisition, we realised there was a space between the GH5 and the VariCam LT,” said EMEA Marketing Manager Nela Pertl. “With its compact size and new 5.7K sensor, the EVA1 fills that gap for a variety of filmmaking applications.”

The EVA1 contains a newly designed 5.7K Super 35mm-sized sensor for capturing true cinematic images. By starting at a higher native resolution, the 5.7K sensor yields a higher resolving image when down sampled to 4K, UHD, 2K, and even 720p. The increased colour information results in a finer, more accurate finished image.

One of the key features of the VariCam 35, VariCam LT, and VariCam Pure is dual native ISO. Utilising a process that allows the sensor to be read in a fundamentally different way, dual native ISO extracts more information from the sensor without degrading the image. This results in a camera that can switch from a standard sensitivity to a high sensitivity without an increase in noise, or other artifacts.

“On the VariCams, dual native ISO has allowed cinematographers to use less light on set, saving time and money, as well as allowing for a great variety of artistic choices. The EVA1 will include dual native ISO, but the camera is currently being tested to determine final ISO specifications,” added Nela Pertl.

The ability to capture accurate colours and rich skin tones is a must for any filmmaker. Like the VariCam lineup of cinema cameras, the EVA1 contains V-Log/V-Gamut capture to deliver high dynamic range and broad colours. V-Log has log curve characteristics that are somewhat reminiscent of negative film and V-Gamut delivers a colour space even larger than film. The EVA1 will also import the celebrated colourimetry of the VariCam line.

Weighing only 1.2Kg (body-only) with a compact form factor (17cm x 13.5cm x 13.3cm) and a removable handgrip, EVA1 can be used for efficient handheld shooting applications and can also be mounted on a drone, gimbal rig, or jib arm for complex yet smooth camera moves. There will also be numerous mounting points and Panasonic is currently working with top accessory makers to allow further customisation with the EVA1.

Ideal for indie filmmakers, the EVA1 records to readily-available, lower-cost SD cards. The camera can record in several formats and compression rates, and offers up to 10-bit 422, even in 4K. A complete breakdown of recording formats will be available at the time of the EVA1’s release.

The camera utilises a native EF-mount, giving shooters access to the broad EF lens ecosystem, including dozens of cinema-style prime and zoom lenses from numerous manufacturers. Electronic Image Stabilisation (EIS) is employed to compensate for camera shake and blurring, which will help smooth out handheld or shoulder-mount shots on documentary or run-and-gun projects. Behind the lens mount, an integrated ND filter wheel in 2, 4, and 6 stops allows for precise exposure control. The EVA1 also allows the IR Cut filter to be swung out of the path to the sensor at the push of a button. Unique photographic effects and night vision imagery are possible with this control over infrared.

As a professional video production tool, the EVA1 offers dual balanced XLR audio inputs and 4K-capable video outputs in both HDMI and SDI. In a future firmware upgrade, EVA1 will offer 5.7K RAW output to 3rd party recorders.

The EVA1 will ship this autumn for under €8,000 (body only).

6 Tips for Getting Sharper Wildlife Photos With a Super Telephoto Lens

29 May

In recent years, super telephoto lenses by third-party manufacturers such as Sigma and Tamron have been made available on the market for really reasonable prices. Earlier on, photographers had no choice but to spend a huge amount in order to buy a super telephoto lens, but now these third-party lenses make it more affordable. One such super telephoto lens is the Sigma 150-600mm f/5-6.3 DG OS HSM, which allows you to get much closer to a distant subject.

Using a super telephoto lens for wildlife photography is in itself a skill to master as you may not get sharp and clear results when you first pick up the lens. The tips below will help you get work better with a super telephoto lens so you can capture sharper wildlife photos going forward.

Wildlife photography telephoto lens 01

#1 – Choose the correct shutter speed

Selection of the best shutter speed is one of the most important tasks when doing wildlife photography. There is a standard rule which says that the shutter speed should be equal to or faster than the focal length of the lens you’re using. So, if you are shooting with a 500mm focal length, then you need a shutter speed of at least 1/500th or faster (1/1000th, 1/2000th, and so on).

Shooting at a shutter speed slower than 1/500th can introduce camera shake and thus will affect the sharpness of the image. However, if your lens features image stabilization technology, you can then shoot at a slower shutter than the focal length. How much slower will depend on the performance of the technology for that particular lens.

NOTE: This rule is applicable for full-frame digital cameras. If you are using an APS-C sensor camera, then you also have to multiply the focal length by the crop factor of your camera brand (1.5x for Nikon, 1.6x for Canon, etc). In this case, the focal length would become 750mm with a Nikon APS-C sensor camera and thus a shutter speed of 1/750th of a second or faster needs to be used to get sharp photos.

Wildlife photography telephoto lens 07

Usually super telephoto lenses such as the Sigma 150-600mm f/5-6.3 DG OS HSM perform the best from 150mm to 500mm, and as you go beyond 500mm the sharpness starts to lessen. So try and avoid using a focal length which is towards the maximum limit of a telephoto lens.

#2 Use the right aperture value

In wildlife photography, depth of field plays a great role in helping to make the subject stand out from the background. In case you are not aware, shooting with wider aperture (smaller aperture values like f/2.8) helps you to achieve shallow depth of field. This results in a photo where the subject is sharp and well segregated from the background, which itself will be out of focus.

But this does not mean that you blindly shoot using the smallest available aperture value. Instead, I recommend that you shoot at the aperture value which is the sweet spot of your lens. Usually the sweet spot of a lens is 2-3 stops higher than the smallest aperture value. So it would be around f/11 if you are using the Sigma 150-600mm f/5-6.3. Shooting at the sweet spot aperture value allows you to get maximum possible sharpness in the photo, along with decent depth of field. By the way, you would likely be shooting at a focal length such as 500mm or so, and in that case, you would get shallow depth of field even at f/8 or f/11.

Wildlife photography telephoto lens 03

#3 – Selecting ISO sensitivity

ISO sensitivity is one of the sides of the exposure triangle which needs to be adjusted as per the shutter speed and aperture value required for the shoot. In the case of wildlife photography, you will have to compromise on the ISO sensitivity over the other two elements of the exposure triangle. Why?

You will have to use a fast shutter speed in order to freeze the motion of the subject and an aperture value which is not that wide in order to capture sharper photo. This is the reason why you might have to increase the ISO sensitivity value in order to capture a well-exposed photo. So the ISO should be the last exposure setting that you adjust in order to correctly expose the frame.

Wildlife photography telephoto lens 04

#4 – Use a tripod or monopod for stability

Considering the fact that the super telephoto lenses are really heavy, it is important and advisable to mount them on a tripod or a monopod. Almost all telephoto lenses have a tripod collar for mounting the lens on a tripod or a monopod. This will enable you to concentrate more on the surroundings and the movement of the animals/birds instead of worrying about carrying the weight of the lens.

If you shoot handheld at telephoto focal lengths such as 300mm, 400mm and so on, you are bound to get shake in your photos. As a precautionary measure, it is better to carry a tripod or a monopod along every time you plan to shoot wildlife.

Wildlife photography telephoto lens 05

#5 – Image Stabilization mode in your lens

In a situation when you need to pan your camera along with the moving animal or bird, make sure that you have switched on the image stabilization on your lens. This is helpful in case you are shooting handheld, as it reduces the shake that is caused while panning or tilting the camera. Image stabilization mode can be found on lenses as IS on Canon lenses, VR on Nikon lenses, OS on Sigma lenses, VC on Tamron lenses and OSS on Sony lenses.

But in case you are using a tripod or a monopod as advised above, switch off the image stabilization mode on the lens. If you keep it switched on, the image stabilization feature introduces minor shake which in turn reaches the camera mounted on a tripod or a monopod. So in order to eliminate this minor shake you must switch off the image stabilization mode on your telephoto lens.

Wildlife photography telephoto lens 02

#6 – Explore Back Button Focus

If you are not already using the back button focus method to lock the focus on the subject, then you must be half-pressing the shutter release button to do the needful. When you use the shutter release button to lock focus, you are further contributing introduction of minor camera shake.

By using the back button focus technique, you can dedicate one of the buttons located on the back of your camera to focus. By doing so, you are then balancing the weight of the camera as you press the button on the back side. Not only does it reduce camera shake, it also helps you shoot at much faster rate as compared to the traditional approach.

Wildlife photography telephoto lens 08

Conclusion

Shooting with a super telephoto lens is a delight, but it is also really important that you understand the technical aspects of using it to get sharp results. Do not be disappointed if your initial shots are not as sharp as you expected them to be.

Make sure that you are using the right shutter speed and aperture values, these two elements of the exposure triangle contribute the most to the sharpness of your photos. If possible, use a tripod or monopod and mount your telephoto lens on it to avoid any possible camera shake. In case you are shooting handheld, switch-on the image stabilization feature on the lens to further reduce the shake caused during panning or tilting of the camera.

Irix introduces super wide-angle 11mm for full-frame DSLRs

21 Feb

New optics manufacturer Irix has announced a second extreme wide-angle lens for full-frame DSLR users that will join the existing 15mm F2.4. The new lens is a manual focus 11mm F4 which will come in two versions – Blackstone and Firefly – like the company’s first lens.

Constructed using 16 elements arranged in 10 groups the lens offers a nine-bladed iris with apertures from F4 to F22. Electrical contacts allow users to control aperture values from the camera body and for aperture values to be recorded in EXIF data.

Irix says this new 126° lens is unique because it exhibits only 3.13% curvilinear distortion on a full-frame sensor and shows test images to back up the claim, along with MTF charts that describe the expected resolution.

Available in mounts for Canon, Nikon and Pentax the lens is weather-sealed and comes in rugged or lightweight versions. The Firefly model is 12% lighter than the Blackstone, but the Blackstone is made from aluminum-magnesium alloy, features a metal-grooved focusing ring and has an anti-scratch coating. Those working in low light conditions might be glad of the Blackstone’s engaged markings that glow in the dark. As the forward element of both versions is so large, and the angle of view so extreme, the company has integrated a filter slot at the back of the lens for 30x30mm gelatin filters.

There is no indication yet when the lens will begin shipping but it is listed for sale on the company’s US website, with the Blackstone version costing $ 825 and the Firefly $ 595.
For more information see the Irix website.
