2011年4月11日开幕的美国 NAB上， SONY将首次展示其神秘的顶级 4K数字电影摄影机。 这将会是一个超越目前市场上所有竞争对手的产品。

SONY已经修改了 2010年的 4K End to End介绍会上的 6K x 3K（1,770万像素采样率）的方案，采样像素将提升到：8,768 x 2,324 （20.4 Megapixels）。而次前公布的 12Bit输出，也将提升到 16Bit输出。

此摄影机在正常拍摄模式下，全像素将支持：1p--72p拍摄，在高帧速模式下，4K支持 120fps。

据说将采用浮动价格区间的定价方式， 根据不同配置定价，基本组的价格将比 F35便宜， 价位将从：$100K---$300K之间。

Sony Prepping Monster 4K Cinema Camera For NAB Debut

This news is above and beyond the budgets of our readers, sure, but to be honest it’s also above and beyond the budgets of most major filmmakers. Digital cinema cameras like the one Sony is expected to announce this month at NAB run in the $100K-$300K range, and often aren’t even offered for sale, only for rental at daily costs that would buy you a RED. But hey, money issues aside, this is going to be a beast of a camera.

It’s got a Super-35mm-sized CMOS sensor pulling down 8768×2324 pixels, which makes for a pretty weird aspect ratio. Good thing it’s reducing that to 4K, or else we’d be watching some widescreen movies in a couple years. Perhaps the more impressive bit is its color space: 16-bit RAW in 16:8:8. That’s a lot of leeway for the editors, cinematographers, and color techs to work with.

The rest of the info can be found over at Film and Digital Times, which appears quite impressed with the camera. NAB happens in early April, so we’ll update you then.

As for big digital cinema’s nemesis RED, Jim Jannard had only this to say: “At least people can now stop thinking about 1080p!” Which really is true, even the high-end digital cinema gear has been aimed at 1080p for the last few years. Soon a 4K process may make its way all the way to a theater near you.

New Sony Camera: 4K and Beyond

The bar has been raised again. Sony is planning to show the prototype of a new >4K motion picture camera at NAB 2011. This could  be historic.

We’re an hour southwest of Tokyo at Sony’s Tech Center in Atsugi. No pictures allowed, but we spent time with the development team and executives involved in this latest addition to the Sony CineAlta product line. It doesn’t have a name yet, but instead of calling it the Next CineAlta Camera, let’s give it the working title of Cine Altissima. She is not a mere 4K motion picture camera. Behind the PL mount, there’s an 8K sensor: 8768 x 2324 pixel single CMOS sensor (that’s 20.4 Megapixels) — Super35 3-perf size,  16-bit RAW output, 16:8:8.

Altissima covers a wider color space than any other digital camera, and will include ACES Film Emulation.
In normal mode, the new Sony 4K camera will shoot from 1-72 fps. In HFR (High Frame Rate) mode, she’ll go from 1-120 fps.

A 1 TB Memory Card recording at 24 fps will store about an hour of “footage.” A dockable SR Memory Card Recorder can attach to the camera for recording directly to an SR Memory Card of 256 MB, 512 MB or 1 TB. I imagine that other recording options will become available, both onboard as an accessory digital “magazine,” and tethered by cable in a separate case. Debayering for instant viewing or playback  will be available with external real time hardware.

Altissima has the familiar look, in prototype form, of a high end motion picture camera: hints of F35, Arricam Studio or Panaflex Millenium. Power will be dual 12 volt; consumption is expected to be less than a Sony F35.
What does the image look like? The pictures from the prototype, on a large 4K monitor, were stunning. Rich blacks, incredible detail, superbly sharp. I’m guessing the native ISO sensitivity is around 800-1000 — just quick speculation in a dark test room and a tabletop set.

I think what makes this new camera possible is the fact that Sony manufactures the five secret sauces essential to practical 4K: sensor, storage, software, station, and screening. Sony makes the 8K sensor that subsamples to 4K. That’s a significant amount of headroom; higher resolution from this sensor might be seen in the future. Storage: Sony makes the SR Memory Cards–they have an impressive 5 Gbps sustained data rate. Station: Data from the SR Memory Card is downloaded, cloned, and copied via Sony’s SRW-5800/2 deck. Software: Sony announced that Avid, Final Cut Pro and other major editing systems will handle all this. Finally, Sony’s 4K digital projectors have been installed in more than 7500 theaters worldwide.
Sony’s new Cine Altissima camera has the potential to be the big breakthrough into practical 4K production. This isn’t the trickle of traditional workflow. This is the floodgates opening.

此前 SONY在ISSCC 2011上，展示了新开发的用于数字电影摄影机的超高速 CMOS传感器。

全域快门， 6K x 2.9K的， 1,770万像素。全像素（6K x 2.9K）输出时， 12Bit的采样帧率达到：120fps（数据传输率达到：34.8Gbps［4.35GB/s］）；当以 14Bit输出时，全像素1,770万（6K x 2.9K）采样的帧率也能实现 60fps的高速输出。 1080p的 12Bit输出，采样帧率能超过1,000帧。展示的传感器的光学尺寸是对角线：27.5mm（完全对应 16:9的 Super-35mm的规范）。

偶一直认为， SONY的 4K摄影机一定是这枚传感器毫无疑问了。 没想到才不到几天，方案已经完全推翻了。已经变成了：8K 的 16Bit输出的传感器哈（不是偶不知道，而是这世界变化太快哈）^13^

价格能买几十台RED

它又不是按照8768×2324 这个分辨率输出影象。  这个传感器是多像素合并后的输出 4K影像，传感器的取样像素是 8768×2324 而已。

就和 F35一样，从取样像素 5,760 x 2,160来看，很不符合宽银幕的习惯。但实际上人家是多个取样像素合并成一个合成的逻辑像素来使用。

SONY这个 4K摄影机也是这样。

优秀员工

怎么如此的扁？

YY一下还是可以的，估计摸都摸不到，摸到了也关自己鸟事

看把你兴奋的
