发帖数: 2063 | 1 丹麦厂商Phase One发布新款中画幅数码后背产品，包括IQ180、IQ160、IQ140三款。其中IQ180像素数达到8000万。并且，该后背使用的CCD与去年 Phase One旗下Leaf品牌推出的8000万像素Aptus-II 12并不相同，在其基础上又进行了升级。
该系列数码后背使用的中画幅CCD由Dalsa公司制造，IQ180 CCD尺寸53.9×43.4mm，像素数8000万；IQ160 CCD尺寸53.9×43.4mm，像素数6050万；IQ140 CCD尺寸44×33mm，像素数4000万。即使是最小的IQ140，其感光元件尺寸也比135单反的36×24mm大得多，这也是中画幅机型画质的保证。
在超大画幅超高像素的基础上，Phase One新机还拥有16bit A/D转换器，动态范围12.5Evs，感光度ISO 50-800，支持Sensor Plus模式，在像素数降至1/4的情况下可将感光度提升至ISO 200-3200。
除此以外，新系列还搭载了“Retina”视网膜屏幕，3.2" 115万像素并支持多点触摸操作。为保证8000万像素超大尺寸照片文件的存储需求，Phase One对存储系统进行了升级，支持USB 3.0接口用于传输照片，还支持FireWire 800接口用于联机拍摄。
Phase One IQ180将于4月底上市，IQ160和IQ140则会在5月底推出。该系列机背的入门价格为21,990美元(约合人民币144,671元)。

When it comes to really high-end digital cameras for serious pro-shooters
they often come with a back containing the sensor and mechanicals as a
separate piece from the body. One of the latest such high-end cameras is
Phase One’s IQ180, and the thing has a massively high resolution image
sensor.
The IS180 packs in a sensor that has a whopping 80-megapixel resolution. The
back in the photo above is connected to a 645DF camera body. The body is a
medium-format unit and this is the sort of camera favored by the high-end
shooters of hot models that need all the resolution they can get.
The camera back also has a faster memory interface to allow for continuous
shooting at really high resolutions. The back also gets USB 3.0
specification support to allow for transferring those photos to a computer
faster. Plus, it’s got a high-resolution 290ppi (think Apple Retina Display
) multitouch back for easily viewing and interacting with images on-screen.
The device will land at the end of April at an unknown price. I would expect
it to be in the many thousands of dollar range. | d*****0
