The Shootout is here! See:-http://www.16-9.net/lens_tests/pentax85/index.htmlTests were carried for close and long distances, wide opened and stopped down.Do note that the lenses were tested on a Canon 400D (XTi) body, i.e., cropped, but not in Full Frame.The Pentax is clearly a winner! :-D =Victory=I like better the colours, sharpness and more importantly the image transparency of the Pentax,
