http://www.fotofach.de/ 213-203 http://www.fotofach.de/festbrennweiten-erfahrungsberichte/sigma-180mm-35-ex-dg-apo-hsm-if-makro/ The Sigma AF 180mm f/3.5 EX HSM APO macro is a very capable macro lens with very high resolution figures, marginal vignetting and non-existing distortions. Unfortunately CAs are a on the high side which is unusual for a tele fix-focal lens - this is a correctable issue though (via PS ACR, RawShooter, etc.). The build quality is very high and thanks to HSM the AF operates pretty fast and virtually silent. Compared to similar genuine brand lenses the AF 180mm f/3.5 EX APO macro is an absolute bargain at less than half the costs. However, all-in-all the Sigma AF 150mm f/2.8 EX HSM APO macro DG was a little more convincing. ]]> Sun, 07 Mar 2010 21:54:54 +0100
