全能百搭镜头接口：PL、EF、M43
JVC新发布的三款机器
Super 35mm传感器，3840×2180最大拍摄分辨率以及150Mbps码流，JVC赶在其他品牌一大波新品发布之前率先发力，推出了新一代4K手持摄像机GY-LS300，同时还发布了几款小传感器的4K摄像机HM200/HM170。这几台机器除了显而易见的4K亮点外，4K、HD模式下4:2:2SD卡录制也是个亮点。
这几台机器应该会在2015年CES或者CP+上正式发布，不过英国某网站已经上架了，LS300为4450美元、HM200为2995美元、HM170为2495美元。

Compact, convenient, and ultra high definition! The GY-LS300 is equipped with a 4K Super 35mm 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 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. | [size=+1]Super 35mm CMOS 4K Image Sensor |
 The GY-LS300 features a JVCKENWOOD AltaSens 4K CMOS Super 35mm image sensor uniquely combined with an industry standard Micro Four Thirds (MFT) lens mount. Super 35mm 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 35mm 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. |

*Mount adaptor may be required. Adapters are available for PL, EF, Nikon, C, and other lenses.
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.
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 formatsLower resolution H.264 files (480x270p and 960x540p) 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.
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. And now RTMP protocol makes it easier than ever to deliver your live streams to content delivery networks such as USTREAM and YouTube. Just press one button and you're streaming to the world!
