GY-LS300 primed for cinema mode

New version 2.0 firmware for JVC’s GY-LS300 handheld Super 35 4K camcorder has added some significant features. These include a film-look JVC Log mode, Cinema 4K/2K recording modes, Prime Zoom, which allows zooming using prime lenses, and a histogram. It can also now trigger recordings via HDMI/SDI and has JVC LUT support for the Atomos Shogun recorder.

JVC Log allows it to deliver wider latitude and high dynamic range – up to 800%. The free upgrade also adds 4096×2160 Cinema 4K and 2048×1080 Cinema 2K recording at various frame rates, with a 17:9 aspect ratio for digital cinema presentations, plus a full HD output via HDMI/SDI when doing 4K recording, for HD monitoring.

The Prime Zoom takes advantage of JVC’s 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 prime lens, the image can be adjusted between the maximum and minimum scan area using the zoom rocker, offering 2.3x maximum zoom for HD or 1.25x zoom for 4K. It can also be used as a lens extender for zoom lenses.

V2.0 also adds colour matrix adjustment, spot meter for exposure, and a black paint setting to precisely adjust the colour temperature of master black. A new 70Mbps recording mode allows 4K recording on economical Class 10 SDHC/SDXC memory cards. The GY-LS300 includes a HD streaming engine with Wi-Fi and 3G/4G connectivity for live HD transmission.
