The JVC GY-LS300 camera had a firmware update last year that permitted the camera to shoot at 120fps full HD. Now the company is releasing a new update that adds the capability of recording of 4:2:2 (8-bit) 4K @ 24/25/30p video to internal storage. The camera previously only recorded at 4:2:0 color space. Not only that, the camera now can output to the Ninja Inferno external recorder a 4k UHD stream at 50p or 60p for 4k slow motion goodness.
The Version 4.0 firmware upgrade is free of charge for all current GY-LS300 owners and will be available in late May. This camera seems to continue to be supported by JVC due to its popularity and seems, for now, to be their best bet to offer a camera that competes with the Sony FS5 or Panasonic DVX 200 for example with a low price of around $2600 USD.
