The Nikon D800 is an impressive 36mp which puts in the same realm as SOME medium format cameras. The Camera Store decided to film a video comparing the D800 and the similarly equipped Hasselblad H4D which has a 40 megapixel sensor. The Hasselblad has the advantage of a much larger sensor and a better, sharper lens but the D800 censor is designed to shoot at higher ISOs. Which camera will win each test? You'll have to watch to find out.
