Hello, I bought this for my optical D3100 and I am very proud! I used me for wildlife photography. This perspective has several qualities: -the price -the rapid motorization -the stabilization -the manufacturing However, the AF is sometimes difficult to distinguish the subject in an important vegetation. If you want to buy a 300mm, do not hesitate to buy this one: it is better than tamron or sigma and that's what the nikon !! I got the goal after a few days wrapped in the original box with a lens hood (almost essential in my opinion;) with the same warranty! The greatest quality of this lens is of course the price / quality ratio!
