Solid State 4K: JVC GY-LS300CHU Camera & Atomos Ninja Inferno

Solid State 4K:

JVC GY-LS300CHU Camera

and Atomos Ninja Inferno


Chuck Gloman

JVC has updated the firmware on its GY-LS300CHU 4K solid-state camera and recorder. The camera features: a Super 35 sensor and internal recording to SD cards, as well as interchangeable lenses and the ability to automatically trigger an external SSD monitoring device like the Atomos Ninja Inferno. This review will describe the specifications of both the camera and recorder, evaluate how it performed on two different projects, and share what budding filmmakers believed were the strengths and weaknesses.


JVC GY-LS300CHU Camera

Having used JVC equipment since the early 1980s, I noticed the technology has made great strides forward in getting high quality images with a camera that is one- third the size of its predecessors. With many people shooting in 4K and recording to solid-state CF or SD media today, the camera body itself has been the main focus (pardon the pun). The two factors that determine the quality of the images are the sensor and the glass up front. Our GY-LS300CHU was provided with a Metabones EF-M43 mount that allowed us to use our equipment cage’s large selection of EF mount Cinema Series lenses instead of the camera’s standard Micro Four-thirds mount.

The Super 35mm Progressive CMOS sensor captures true 4K (4096 x 2160) with the external Atomos Ninja; UHD (3840 x 2160 in 30p and 24p); and MPEG-4 QuickTime HD (1920 x 1080 in 59.94p, 59.94i, 29.97p, and 23.98p in the XHQ mode, and 59.94i, 30p, 23.98p and 1280 x 720/60p in UHQ mode). The AVCHD codec is available with 1920 x 1080 in 60p in the HQ mode at 28 Mbps, or 24 Mbps, as well as SP mode at 17 Mbps. In addition, the camera also shoots in the SD mode (QuickTime and AVCHD) at 8 Mbps; → continue…

Lensrentals.com Compares the Canon EF 85mm f/1.4L IS Against the Competition

By Canon Rumors Lensrentals.com has posted a comparison between the EF 85mm f/1.4L IS, EF 85mm f/1.2L and the Sigma 85mm f/1.4 Art. This comparison is not their usual scientific endeavour using OLAF, this is a bit more of a real world comparison by looking at images with our own eyes.

KipperTie Revolva – RED Lens Mount With Built In ND Filter Wheel

By Tim Fok

KipperTie has announced Revolva, a new mount for the DSMC2 RED cameras offering a PL or EF mount with built-in ND wheel. The wheel can be swapped out quickly to more ND or even a diffusion set.

Kippertie has been known for making filtration related RED products for some time, the Revolva may just be their most significant yet.

With a name and colour wave uncanny to another favourite UK camera accessory company, the Revolva is suitably garish in appearance as with many RED-related products.

It’s a lens mount and ND wheel built in one. Both PL and EF mounts will be available, electronically also for aperture changes and lens data (exactly the same as the RED EF mount).

The 4-filter wheel (or cartridge) can be quickly removed and switched out to one of the following

Clear, 0.3, 0.6, 0.9 (0-3 stops)

1.2, 1.5, 1.8, 2.1 (4-7 stops)

Gold, Carbon, Pearl, Optical Clear (diffusion set)

Backfocus issues are supposedly non-existent:

“Revolva compensates for back focus with its high refractive index rear optical window, combined with a precise and specific flange depth. As long as you have a Revolva cartridge fitted, back focus will be correct.”

Like any standard lens mount for DSMC2 RED cameras, the Revolva sits in front of your OLPF; it does not affect this in any way.

There’s a very handy FAQ on the KipperTie website, it highlights a few downsides:

  • Certain lenses just don’t fit.
  • A small number of lenses vignette on VV.
  • Gate flare when not using a sunshade is potentially different from normal expectation.
  • Certain combinations of camera accessories will obstruct fitment and require changes to your rigging.

Behind the scenes: Trapped in a blizzard with the Fujifilm GFX 50s

Photographer Josselin Cornou recently got his hands on a Kipon EF-GFX adapter and Tamron 15-30mm F2.8 lens, which he couldn’t wait to slap onto his Fujifilm GFX-50S. But what to shoot? So he hopped into a car and headed up to Thredbo in the Snowy Mountains of Australia… with a $6,500 camera… what the worst that could happen!?

Cue Murphy’s law.

As fate would have it, Josselin and his expensive new gear got caught in an extreme blizzard—an experience that seems to have both terrified and delighted him, if you go by his squeals of joy in the video. Fortunately for us, it gave him a chance to test out all three of his new toys (the Fuji GFX, Kipon Adaptor, and Tamron 15-30mm F2.8) in some of the harshest conditions you might ever dream of taking them.

You can hear what he had to say in the video up top, but he was also kind enough to share some more thoughts with DPReview readers in writing. So, here goes. Take it away Josselin:

About the Kipon Adaptor

Pros: the adapter allows you to change the aperture of the lens from the GFX.

Cons: there is no connection to the camera.

Ultimately, I found this to be a great tool to use any EF lens on the Fujifilm GFX. There is no weather sealing on the current version, so I had to remove the adaptor when it was drying. Still, it did a really great job in incredibly tough conditions, and it’s still fully functional even after freezing solid!

Having an adaptor with aperture control is a must if you want to use Canon glasses on the GFX.
