full-frame 6.3fps, half frame 12M的话说不定可以12fps, 至不济也有9fps

没啥戏啊

专业全副还要等到今年9月，中端全副怎么也得明年下半年，怪不得C一点也不急啊，5D看来还有1-2年的生命期啊

等吧!

Tokyo, Japan – Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm/Type 2.7) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

Development background

In recent years, the demand for digital SLR cameras featuring high resolution and wide graduation ranges capable of capturing every detail of the subject matter has continued to increase, particularly among high-end amateur users. Additionally, the increasing user requirement to shoot from the same focal length and angle as 35mm film cameras using interchangeable lenses has led to significant interest in the development of 35mm, full size CMOS image sensors.

However, there are a number of technical challenges to developing full (large) size image sensors, such as the propagation delay caused by using extended power circuitry and signal lines, and the difficulty of maintaining uniform sensitivity and signal saturation across the surface of the screen.

Furthermore, because current semiconductor exposure systems are unable to cover the entire chip surface of 35mm full size CMOS image sensors, multiple exposures are required. This results in the difficulty of accurately controlling exposure variance and matching circuit patterns.

Advantages of this device

The newly developed CMOS image sensor combines unique circuit design technology with Sony's advanced fabrication expertise, including a system of joining multiple exposed patterns together and advanced planarization for minimizing fluctuation, to realize 35mm, full size, 24.81 effective megapixel resolution. Sony’s“Column-Parallel A/D Conversion Technique - also provides each column within the sensor with its own A/D converter, minimizing image degradation caused by the noise that arises during analog processing while at the same time delivering an extremely high signal conversion speed.

The enhanced image quality generated by the sensor’s 24.81 effective megapixel resolution, wide range of graduation expression achieved by its full size broad dynamic range, and the low noise, high resolution, ultra-responsive performance provided by Sony’s Column-Parallel A/D Conversion technique enable it to meet the ever-increasing requirements within high performance digital SLR cameras.

Sony will target for mass production of this CMOS image sensor within this year.

Major features:

    * 1)High picture quality in 35mm full size image sensor with 24.81M effective pixels
    * 2)“Column-Parallel A/D Conversion method” achieves high S/N and high-speed imaging
          o ·CDS/PGA(24dB)Circuit (PGA: Programmable Gain Amplifier)
          o ·12bit-AD Converter on chip
          o ·Diversified readout mode
          o ·All-pixel scan mode 6.3 frame/s (12bit)
          o ·Window readout
    * 3)High-speed digital output(12 channel parallel LVDS output)

Device Structure:

    * Image size Diagonal width 43.3mm (Type 2.7)
    * Total number of pixels 6236(H) x 4124(V) approx. 25.72M pixels
    * Number of effective pixels 6104(H) x 4064(V) approx.24.81M pixels
    * Number of active pixels 6096(H) x 4056(V) approx.24.73M pixels
    * Chip size 41.0mm (H) x 31.9 mm (V)
    * Unit cell size 5.94µm (H) x 5.94µm (V)

这是这块CMOS的参数，还不是a900的参数...........

Sony plans to begin mass production of the new sensor in 2008, which puts it on track for implementation in cameras that could be announced at Photokina 2008 in the fall.

sony才不傻，二流的给棒子交换专利

哈哈
变得好快啊！

Number of effective pixels 6104(H) x 4064(V) approx.24.81M pixels
Number of active pixels 6096(H) x 4056(V) approx.24.73M pixels

至少D3的来自索尼，相信不久D3X也将面世

呵呵，赶紧来压￥100啊！！！

Sony has announced that it has developed a new CMOS sensor for digital SLRs that has the same imaging area as a frame of 35mm film and offers 24.81-megapixel effective resolution. The company says it will capture images with a broad dynamic range and high signal-to-noise ratios. Its full-frame 6.3fps scanning mode also promises to support fast digital SLR shooting modes.

The bottom line: Full-frame digital SLRs from Sony and other manufacturers that use Sony sensors -- notably Nikon -- are surely on the horizon. Sony plans to begin mass production of the new sensor in 2008, which puts it on track for implementation in cameras that could be announced at Photokina 2008 in the fall.

A900参数出来了，全副，6FPS连拍，动态范围看来比较佳，ISO佳。也许要秋天才能出。。。

连拍数少了点，要不这个给A800用？

就那个意思啦，啧啧

恩，鸡蛋说canon的全副利润率至少有50%，我们少拿一点，45%就行了嘛

两千四百万

全幅加一块CCD辅助取景即可
