谢谢你提供这个信息， 这证明了我说的在正常光照下，5d2 比D700 清晰。 但是Dpreview的比较也有问题， 你可以发现在

这是我从你推荐的那篇Dpreview中摘录的： 供大家参考。 Like the comparison with the original 5D, this comparison presents a problem; the 5D Mark II has almost double the pixel count of the D700, making a direct comparison at 100% rather moot. That said, on a per pixel basis, the 5D Mark II is sharper and produces more fine detail, helped by Canon's slightly higher in-camera sharpening. There is no visible noise in either of the cameras at their base ISO settings. If you need a lot of resolution for very large prints there's no doubt at all that the EOS 5D Mark II is several strides ahead of the D700.
