http://www.fotofach.de/ 202-198 http://www.fotofach.de/festbrennweiten-erfahrungsberichte/sigma-30mm-14-ex-dc-hsm/ We all know that zoom lenses are compromises regarding speed and performance but we expect fix-focals to perform better than that. Sigma AF 30mm f/1.4 EX HSM DC may perform pretty good in absolute terms but for a fix-focal the lens disappoints a little. The center performance is exceptionally high but the borders are not all that impressive. The other image parameters such as distortions, vignetting and CAs are Okay but nothing to rave about. So at the end of the day the only differentiator is its ultra-large aperture - it's up to you whether this is good enough compared to classic 28mm or 35mm lenses. ]]> Sun, 07 Mar 2010 21:46:47 +0100
