New Sigma lens is sharp throughout, although not cruelly over-sharp, so subjects should be pleased enough.

Review
Sigma 85mm is very fast and tack-sharp lens, both in the center and at the edges of the frame.

Having just joined the Art lens party, these things are like something from another planet! Amazing quality- both build and optics. Just crazy good. Congratulations Sigma!
