Compact, convenient, and ultra high definition, the GY-LS300 is equipped with a 4K Super 35 CMOS sensor and accommodates a wide range of cinema and photographic lenses and adapters for dazzling cinematic effects. Create hours of pristine recordings on SDHC/SDXC media in a variety of image formats including 4K Ultra HD, Full HD with 4:2:2 sampling, SD and web friendly proxy formats. Conventional DSLR cameras simply can’t match the high reliability, long recording time and ergonomics provided by JVC’s GY-LS300. Its dual codec design allows you to make 2 copies of your program simultaneously. You can even stream live HD over the internet to content delivery networks such as USTREAM while recording full HD. No other removable lens video camera offers this much flexibility in such a compact, easy-to-handle form factor.

The GY-LS300 features a JVCKENWOOD AltaSens 4K CMOS Super 35 high sensitivity image sensor uniquely combined with an industry standard Micro Four Thirds (MFT) lens mount. The single chip CMOS sensor has approximately 13.5 megapixels and achieves a standard sensitivity of ISO 400 with a total of 12 stops of exposure latitude. Super 35 Cinema lenses may be used and will retain their native angle of view.* When the camera is used with MFT, Super 16 and other size lenses, JVC’s proprietary Variable Scan Mapping feature will maintain the lens’s native angle of view. This gives filmmakers the flexibility of using widely available MFT lenses as well as high end cinema lenses. It is also possible to attach the camera to microscopes and other devices using a MFT/C-mount adaptor. The unique combination of the MFT mount, the larger S35 image sensor and Variable Scan Mapping give the camera nearly limitless lens options.

The Micro Four Thirds mount offers full coverage of the Super 35 sensor, as shown in this actual photographic comparison with an MFT sensor. With the GY-LS300, you get all the benefits of the MFT mount plus the benefits of a larger sensor.

JVC Log Gamma (v2.0) :: In normal video shooting, high luminance areas are compressed by using a KNEE curve to achieve 400% dynamic range based on ITU Rec.709 gamma. JVC has added a Log Gamma mode that expands dynamic range by 800% with film-like latitude, preserving more information over the entire dynamic range of the sensor. In this mode, the log images will look extremely flat and lack contrast but contain more information for grading and manipulation in post production giving you the opportunity to create truly cinematic results. To assist you in determining the correct exposure when shooting, the camera’s LCD and viewfinder can be mapped to a look-up table (LUT mode) that will approximate the application of grading in post.

Unique Prime Zoom feature (v2.0) :: JVC’s unique variable scan mapping allows you to dynamically map the pixels on the GY-LS300 4K image sensor to your target output resolution. This feature, most useful when recording in HD, allows you to zoom with prime lenses, or extend the range of zoom lenses. Click the image for a demonstration that shows the effect of dynamically mapping from full 4K scan to 1920 x 1080, which has the effect of zooming the image without loss of resolution or change in DOF. This feature is exclusive to JVC’s GY-LS300 with version 2.0 upgrade.

4K Ultra HD Recording at 150Mbps and Live Output :: Working with 4K has never been easier! Insert an SDHC or SDXC (UHS-I Speed class3) memory card and record hours of 4K Ultra HD (3840 x 2160) material. Recordings are made using the Quicktime (.MOV) file format and are compatible with many popular editing systems. Connect a 4K Ultra HD monitor with a single HDMI cable, and view the camera’s live 4K signal. You can also play back recorded files directly from the camera. The GY-LS300 also downconverts UHD signals to standard HD for output through the built-in SDI or HDMI connectors.

Cinema 4K and Cinema 2K Recording for the ultimate cinema look :: Record images in Cinema 4K (4096 x 2160) at 150 or 70 Mbps, or Cinema 2K (2048 x 1920) at 50 Mbps. Both modes support recording in 23.98p or true 24p to match the frame rate of film.

4:2:2 Full HD recording at 50Mbps :: The GY-LS300 records 4:2:2 HD signals up to 60p at 50Mbps making it an ideal camera for general HD production work. 50Mbps files are stored in the Quicktime (.MOV) format for easy editing. Conventional AVCHD (4:2:0) recording is also possible, providing wide editing compatibility in an array of standard HD and SD formats.

Dual SDHC/SDXC Card Slots :: Dual SDHC/SDXC card slots make the GY-LS300 a truly versatile camcorder, offering such benefits as simultaneous recording and relay recording. In relay recording mode, you can shoot continuously and seamlessly over multiple cards. When one card is full, the camcorder switches seamlessly and automatically to the other card. And because cards are hot swappable, there is in effect no limit to the continuous shooting time in any mode, even with lower capacity cards.

Web Friendly (Proxy) file formats :: Lower resolution H.264 files (480 x 270p, 960 x 540p, 720 x 480i, 720 x 576i, or 1440 x 1080i) may be recorded simultaneously with full HD files. These files are significantly smaller than HD files, and thus are very suitable for immediate posting to the web. A file recorded in the 960 x 540 mode is approximately 1/10th the size of a full HD file recorded at 35 Mbps, and therefore takes a fraction of the time to post. The smaller files may be quickly imported to an iPad for easy editing using iMovie or Pinnacle Studio. Transporting video to the web or back to the studio has never been faster. With the GY-LS300, it is also possible to create SD and HD files simultaneously.

Advanced IP Network Communication and Streaming :: The GY-LS300 features JVC’s latest IP communications engine giving you remote control and monitoring of vital camera functions from a tablet, smartphone, or computer anywhere in the world. Live streaming is possible in HD or lower resolutions, depending on available bandwidth. JVC’s Advanced Streaming Technology (AST) includes Zixi powered Forward Error Correction with ARQ, delivering high quality streams even under challenging conditions. RTMP protocol makes it easier than ever to deliver your live streams to content delivery networks such as USTREAM and YouTube. And with Version 2.0 (available September 2015) streaming is more reliable than ever with Adaptive Bitrate Control. Just press one button and you’re streaming to the world.
