Ok, let us start with some EOS 5D Mark III vs Nikon D800 stuff. Photographer Mike Kobal got both cams in his hands and shares his impressions. Optical Viewfinder: slightly brighter on the 5D Mark III; mirror/shutter: a bit louder on the D800 (click here for audio file 5d3 vs d800 in continuous shooting mode, click here for silent mode); Auto-Focus: 5D3 little bit faster, nails AF almost immediately; sensor aspect ratio: D800 has crop modes and aspect ratio can be set, useful when you have to shot in aspect ratios different from 2:3. Mike’s conclusion: The D800 will appeal to the Studio/commercial photographer with the occasional photo-journalistic assignment, the 5D3 will appeal to the location oriented commercial photographer, the photo journalist and the wedding photographer.
