最近风生水起，传闻 Nikon D400 要上市了。八卦大王蜂鸟网自然不会错过捕风捉影的机会：“极为神秘！传闻尼康D400即将在今夏上市”。在12月份的帖子中，它这么评论：

我们可以看到：它的外观与尼康 D300 相仿，机身背面设计了 3.0 英寸 92 万像素 LCD 屏，感光元件采用了 1480 万像素的 APS-C 尺寸感光元件，连拍速度似乎可以达到了 6.5 张每秒。而且，似乎该产品也加入了 1080P 拍摄分辨率的高清视频节目，与目前佳能的无敌兔完全一致。

该产品的传闻中的具体参数为：

* New 14.8 megapixel DX format CMOS sensor effective 14.3 megapixel
* Self-cleaning sensor unit (low-pass filter vibration)
* ISO 100 – 6400 (with boost up to ISO 25600 and down to ISO 50)
* 14-bit A/D conversion
* Movie capture at up to 1080p 24 fps with stereo sound
* Nikon EXPEED Plus image processor 30% faster than previous EXPEED image processor
* Super fast operation (power-up 13 ms, shutter lag 40 ms, black-out 90 ms)
* Kevlar / carbon fibre composite shutter with 200,000 exposure durability
* Multi-CAM3500DX Auto Focus sensor (51-point, 15 cross-type, more vertical coverage)
* Auto-focus tracking by color (using information from 1005-pixel AE sensor)
* Auto-focus calibration (fine-tuning) now available (fixed body or up to 20 separate lens settings)
* Vignetting control in-camera
* Automatic chromatic aberration correction
* Custom image parameters now support brightness as well as contrast
* Seven frames per second continuous shooting (nine frames per second with battery pack)
* 3.0″ 922,000 pixel LCD monitor
* Live View with either phase detect (mirror up/down) or contrast-detect AF, face detection
* ‘Active D-Lighting’ (adjusts metering as well as applying D-Lighting curve)
* Detailed ‘Control Panel’ type display on LCD monitor, changes color in darkness
* Buttons sealed against moisture
* Same ultra-fast startup and shutter lag as D700
* Scene Recognition System (uses AE sensor, AF sensor)
* Picture Control image parameter presets
* UDMA compatible single CF card slot
* Virtual horizon indicates if camera is level (like an aircraft cockpit display)
* Extensive in-camera retouching
* HDMI HD video output
* Magnesium alloy body with connections and buttons sealed against moisture

追溯谣言起源，可以找到这里：Nikon D400。中间那张 D400 的照片让人五体投地、欲仙欲死。

以目前数码相机业界的信息来看，D400 不会有太多新的突破。无非就是像素多点、连拍快些、实时液晶屏取景、高感光度噪点略少、然后就是高清录像。

那我们心目中的标准数码单反相机是什么样子的呢？

1，全画幅，高保真色彩感光元件。一直不明白为啥适马那块 X3 CCD 不做成全副尺寸的。姑且不计价格，好歹也算一种突破。
2，从硬件和软件两个层面共同实现高感光度低噪点，不要停留在所谓的算法降噪低水平运作。
3，准确的白平衡。这个无语，黑灯瞎火，还有很长的路要走。
4，精确的对焦。佳能跑得欢就不说了，尼康中央对焦框的对焦点也偏下。指哪对哪，要求很低，实现起来却颇费周折。

以上几条，D400 估计都差得很远，最终只有搬出 Nikon D3X 等大杀器才能息事宁人。
