今天DPRVIEW站上突然正式发布了关于谣传中的NIKON D2H数码相机的信息。该产品目前已经得到NIKON公司的证实。
目前已经得知D2H是一款四百万象素的数码相机产品，与前代D1H的高速连拍能力相仿，D2H同样具备相当惊人的高速连拍能力。由于NIKON在D2H中采用了其自己开发全新感光元件“JFET LACAST”，NIKON D2H可以达到每秒连续拍摄8张照片。事实上，JFET LACAST的设计原理类似CMOS感光元件，但传输速度更快，再加上D2H内部的巨大缓存因此可以支持D2H在全画幅的情况下进行高速连拍（最多40张）。
值得一提的是，D2H还提供了一个额外的可选配件。这个叫做WT-1的配件实际是为D2H加上了WI-FI无线数据传输能力（春卷：怎么前几天刚刚说FUJIFILM开发了这个东西，NIKON也就干上了？！）。相机可以通过FTP点对点协议向PC传送数据照片。考虑到D1H、D2H这样的高速连拍相机常用于记者，相信这个无线组件实在是非常有用的。

此外，D2H还拥有一些额外的新特性。包括：11区域的多点对焦系统（MULTI-CAM 2000）、全新的环境白平衡传感器、全新的锂电池、2。5英寸（春卷：超级巨大）21万象素LCD屏幕、38毫秒快门延迟、80毫秒的反光版延迟（100%取景面积）、RAW+JPEG双格式输出。。。
本机预计销售价格为3500美元。
