We went on vacation with relatives, they have a d5100, I have a d40, and so - under the same conditions on a whale, and even on a 35mm 1,8 fix, my pictures are sharper, richer, correctly exposed. In general, amateur photographers absolutely do not need 16 MP, they do not add any quality. And, what disappointed me, modern technologies did not improve the image quality at all, quite the contrary. Added only video shooting. So if you need a high-quality photo - take the d90, the price is the same.
