Nikon vs. canon

Head to Head: Nikon D800 vs. Canon 5D Mark III Canon and Nikon have intensified their ongoing rivalry over the past year, in several exciting ways. Both companies released new top-end full-frame, professional DSLRs (The Canon 1D X and the Nikon D4), as well as new low-end full-frame DSLRs, the Nikon D600 and Canon 6D. But The Big Two didn’t stop there, releasing two mid-range full-frame cameras, as well. While the $2999.95 Nikon D800 and $3499.99 Canon 5D Mark III are similar in price and size, they’re actually quite divergent otherwise, appealing to very different kinds of photographers. We’ve fully tested both cameras and decided it was time to put them head to head to see which is the superior model.
