dpreview on the Nikon D800 and D800e

From dpreview.com

With the D800 arriving in camera shops alongside its chief competitor, the Canon EOS 5D Mark III, we have two well-built photographic tools that are capable of outstanding images.

While the 36MP D800 has the resolution advantage over its 22MP rival, it's wise to take note of other differences, like maximum frame rate; here the 5D Mark III takes the edge at 6fps vs 4fps (FX mode). Canon has also managed to take a very complex AF system and ease the learning curve with a well-presented series of presets.

The D800 counters with the ability to output uncompressed HD video and a range of useful crop modes, including the APS-C sized DX format. Most notably though, Nikon has provided a high end offering that comes in at a street price that is US$500 less than the 5D Mark III, representing very strong value for the consumer.

dpreview significantly expanded its review recently to include detailed analysis of the performance of the D800 alongside its closely-related stablemate the D800E. They also added samples and analysis of the D800/E's uncompressed video feature.

By the way, a real estate photography site posted photos that an agent took of some houses for sale using the D800E's in-camera, three-frame HDR capability. He used just ambient light, and the photos are really nice. See them here.
