JVC Professional Video, a division of JVC KENWOOD 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.” Note : Available during September 2015
