Re: Birding and the D7100

No one has mentioned the possibility of using the Sigma 120 - 400mm OS lens. I have this on my D5100. I have no complaints whatsoever - distortions, aberrations, sharpness, hand holdability are all more than satisfactory. It is, in a word, a lens bargain - good quality in all departments at an affordable price and in one published test I saw, very close for image quality at the edges of the frame to the vaunted Canon 400mm lens and much the same in the middle of the frame. The small differences could be completely overcome with software.

It should certainby be on a review list before finalizing a decision.
