After testing Nikon D810 for almost two years, Rishi Sanyal and three other persons posted a full review of Nikon D810 at the Dpreview. Nikon D810 might just be one of the best all-round full-frame DSLRs in the world with its ISO 64 performance allowing it to rival medium format image quality. Nikon D810 now is available for $2,796.95 in most US stores (Amazon/ B&H/ Adorama/ eBay). This is $500 cheaper than MSRP.
