Sigma 70mm f/2.8 EX DG Macro

On a Nikon DX overexposes slightly (no problem, I just leave the body -2 f-stops =0,7eV) in a sunny atmosphere. It has critical sharpness from f/2.8 to f/16. As oposed to other macro lenses, it has a good working distance at 1:1. Very good for portraits, maybe a little too sharp. The construction is top notch, with the mount and the extending front tube made from metal. It does have some CA in contrasting places but that can easily be corrected. In the hands of a macro shooter, this lens can performe alongside the best of the best. Overall, if you're looking for the best macro lens in the business, look no further. This is the sharpest lens ever made!
