GY-LS300 compact 4K camcorder

A prototype model of the new GY-LS300 compact handheld camcorder is being shown at IBC, featuring JVC’s exclusive Super 35mm 13.6MP 4K CMOS image sensor, developed by JVC’s sister company, AltaSens, for 4K 24/25/30p recording. The camera uses Micro Four Thirds lenses, originally developed for DSLRs to deliver cinema-quality images in a compact camcorder, and also accepts a wide variety of stills and video lenses for filmmakers who have already invested in expensive lenses (converters available for PL-mount and other lenses). This first prototype has an advanced codec and onboard recording system, providing 4K imaging on standard SDHC/SDXC UHS-I U3 memory cards, and its dual codec system also delivers simultaneous recording and streaming for both HD/SD and HD/proxy files. The camera features the 4K CAM logo and marks the start of this new camera series from JVC.


Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

  1. Hopes its easier to offload the 4K data files from the 4 SD cards than on my JVC GY-HMQ10 4K cam.

  2. Panasonic apparently passed on further development of a successor to the AF-100.
    It’s funny that JVC decides to market a camera that could have been the AF-200. It will be interesting to hear more about this camera and see how well it competes with other 4K camera alternatives.

  3. Really interested in thi,s I look forward to seeing your review. I like JVC customer care and commitment to development

  4. JVC + MFT = Bad Decision

    What happened with JVC supporting Nikon Lens mount cameras for there 4K lineup?

    JVC JY-HMQ30 has a Nikon mount.(Not released in USA)

    I think Nikon has a much better selection of lenses then Panasonic/Olympus lenses. Plus, with Nikon not delivering to the 4K market, I think JVC would find a nice home supplying the hungry Nikon users with a higher-end cinema/video option. JVC seems to be so inconsistent, I would never invest in there technology, as it can drastically change at any moment.

  5. Actually, several adapters for Nikon lenses to MFT exist, so for Nikon-lens owners this is good news…

  6. True you can use a third party adapter which I’m not a huge fan. Plus MFT usually adds a 2x crop factor versus the typical 1.5x. But I have not seen the full details in this camera.

  7. At IBC this camera was on the show with a nikon lens and Metabones speedbooster: reverses crop factor, makes it almost full frame, gain 1 stop of light and an over all scarper image. MFT & Sony E-mount are the best mounts for compatibility with all other lenses. Metabones speedboosters are very good quality, I own and use several of them with amazing results.
