The lens is fairly big and heavy due to unusually big glass elements but thanks to the design efforts it is already capable of delivering very sharp images straight from f/1.4 and the resolution is truly impressive at medium aperture settings. Distortions, vignetting as well as CAs aren't overly relevant in field conditions. The bokeh can be a bit nervous at f/1.4 but it's smooth and buttery from f/2 onwards. The build quality of the lens is excellent. The HSM AF drive is very fast and virtually silent. All-in-all - highly recommended but watch out for focus accuracy problems. ]]> Sun, 07 Mar 2010 21:48:13 +0100
