Rick Young Reviews the JVC GY-LS300

This is another positive review of this video camera.  Reviews and general excitement for this camera have been mixed.  Some of the footage has been looking not great, and yet other footage looks quite good.  We don’t feel like we’ve gotten to the bottom of this duality yet.  Rick Young likes the color science and dynamic range of this video camera, and the upcoming firmware in September should  only improve on the dynamic range.



Significant Firmware Update for the JVC GY-LS300 4K Video Camera


Updates of note:

  • JVC’s version of Log to improve dynamic range and post processing
  • 4096×2180 and 2048×1080
  • New zooming that takes advantage of crop-factors
  • Histogram (about time!)
  • More bitrate varieties

New Features Include Expanded 4K Recording Formats, Unique Prime Lens Zoom

WAYNE, NJ (August 4, 2015) – JVC Professional Video, a division of JVCKENWOOD USA Corporation, today announced the Version 2.0 firmware upgrade for its GY-LS300 4KCAM handheld Super 35 camcorder. The upgrade adds a “JVC Log” mode that practically duplicates the look of film, plus new Cinema 4K and Cinema 2K recording modes, a unique Prime Zoom feature that uses the camera’s innovative technology to allow zoom capabilities when using prime lenses, and a histogram. Free for all current owners, the upgrade will be available in September 2015.

With the new JVC Log mode, the GY-LS300 delivers wide latitude and high dynamic range – up to 800 percent – to rival the look of film. The camera’s Super 35 CMOS sensor delivers a higher contrast ratio between dark and bright areas within the frame without saturation while providing details within highlights and shadows. V2.0 also adds 4096×2180 Cinema 4K and 2048×1080 Cinema 2K recording modes at various frame rates, each with a 17:9 aspect ratio for digital cinema presentations.

Prime lenses have a fixed focal length, but the GY-LS300’s new Prime Zoom feature takes advantage of JVC’s unique Variable Scan Mapping technology, which was created to electronically adapt the active area of the camera’s image sensor to provide native support of various lenses when paired with third-party lens adapters. When used with a Micro Four Thirds (MFT) prime lens, the image can be adjusted between the maximum scan area and minimum scan area using the camera’s zoom rocker. As a result, the camera can deliver 2.3x maximum zoom for HD or 1.25x maximum zoom for 4K. The new Prime Zoom feature can also be used as a lens extender for zoom lenses.

Version 2.0 adds a histogram display, which is useful for checking the exposure by showing the brightness distribution of the image. The function is accessed through a convenient user button, and the range can be set to provide top and bottom limits. Beyond a histogram, V2.0 adds a color matrix adjustment, spot meter for setting exposure values, and black paint setting to precisely adjust color temperature of master black. Additional performance and streaming enhancements include a new 70Mbps recording mode, which makes it possible to record 4K on economical Class 10 SDHC/SDXC memory cards.

“We listened to our customers and made sure this firmware upgrade delivered the features they wanted, as well as recording modes specifically designed for the 4K digital cinema market,” said Craig Yanagi, manager of marketing and brand strategy, JVC Professional Video. “The GY-LS300 will also have the unique ability to use a prime lens as a zoom lens, which gives shooters even more shooting flexibility.”

Designed for cinematographers, educators, documentarians, and broadcast production departments, the GY-LS300 is the flagship camera for JVC’s new 4KCAM product line. It accommodates a variety of workflows with the latest advancements in 4K imaging and efficient encoding for seamless workflow integration. It also includes a built-in HD streaming engine with Wi-Fi and 4G LTE connectivity for live HD transmission directly to hardware decoders, the Wowza Streaming Engine, and the ProHD Broadcaster server powered by Zixi. With support for various streaming protocols including RTMP, the cameras can stream directly to content delivery networks (CDNs) like Ustream and popular Web sites like YouTube.

JVC DLA-X500R 4k Projector


4K Projects will remain expensive for a while yet to come, but the prices have already began their decline. This project is no exception at around $5,000, and yet at that price it’s significantly cheaper than most of the competition. What’s the catch? It’s not true 4K. It uses the so called e-shift3 technology to combine three 1080p elements together into a single, uniform image.

JVC’s DLA-X500R projector has a resolution of 3840×2160 at 60p (and less) or 4096×2160 at 24p.
