The D800 digital SLR is a revolutionary 36.3 megapixels and the EXPEED3 image-processing engine. This D-SLR is equipped to handle massive amounts of data with ultra-fast speed. D800 also offers superior image quality and supports ISO sensitivities from 50 to 25600.
A real nice camera, but it’s an answer to a non-existent question. High iso performance is mediocre, so it makes a lousy wedding camera. Also, it uses too much card space and hard drive space. I’ll take the 5d MK 3 anyday – and I did !!
