For the most part 4K acquisition has been relegated towards cinematic style production. The majority of professional 4K cameras on the market are “cinema” cameras that utilize interchangeable lenses and have Super35mm (or similar) sized sensors. There has been very little traction in implementing 4K in traditional television production with classic acquisition tools like studio cameras, ENG-style cameras, or hand-held integrated lens camcorders. Sony is aiming to start the shift towards 4K in all forms of video production.
Before NAB Sony already had several good options including the X70, the Z150, and the Z100. All include an integrated powered zoom lens. All of these camcorders have a single sensor image system. The X70 & Z150 use a 1″ sensor and the Z100, the oldest of the group, a 1/2″ sensor. At NAB this year Sony is debuting several new cameras including the new PXW-Z450. The Z450 is based off of the same body as the PXW-X400. This gives users the first Sony traditional ENG shoulder mount form factor camera that offers 4K acquisition. Sony has intentionally stuck with a 2/3″ sensor design for the Z450 so that it will be fully compatible with all of the existing 2/3″ B4 broadcast ENG servo powered zoom lenses that are already in the field. Interestingly it appears that the Z450 uses a single 2/3″ sensor. Additionally, there is an upgrade kit for owners of the 1080p X400 camera. If you currently have an X400, or buy an X400 in the future, and decide you need 4K, you can send your camera to Sony and the camera will be converted to a Z450 for a fee.
Finally, in the studio space, Sony is introducing the HDC4800 studio camera. This is very interesting as this will have a newly designed single Super35mm 4K sensor. The sensor can generate up to 480fps in 4K. Yes, thats 8x slow motion in 4K. This is incredible. The camera has a native PL lens mount meaning that you will need some of the hig-end cine servo glass, like a Fujinon Cabrio, to use the camera in 4K. The HDC4800 has another trick up its sleeve. In the promo video for the camera Sony shows it’s PL lens mount being adapted to a B4 2/3″ mount. When the camera is in 1080p mode it can utilize a 2/3″ crop of the sensor, thus allowing it to be fully compatible with stadium or large studio style box lenses. Also, when in 1080p the maximum frame rate jumps to 16x normal, or 960fps for 60p countries. Imagine a sports game where a couple of these cameras are mounted onto large box lenses with 40x zoom magnifications as your primary cameras and the 4K super slow-mo camera is on the sidelines for close-ups using a 4.5x Fujinon Cabrio 19-90. The HDC4800 is also designed to integrate well with the 4K studio camera Sony introduced last NAB, the HDC4300. The HDC4300 uses 3x 2/3″ 4K image sensors and has a maximum frame rate of 60p in 4K or 480p in 1080p. Both cameras have matched colorimetry for ideal compatibility.
