Anyone have an personal experience to report about this lens? We're in the market for a good 35mm and am wondering if this is a good choice over Canon's 35 1.4L. Lots of reports about how shart it is, but I'm more curious about the focus accuracy - anyone have information about the AF performance?
Af performance is very good. Just as fast as the Canon. It uses Sigmas high speed motor too so everything has been very good. This review pointed out something interesting with the focusing though vs the Canon. The throw for the focus in the Sigma is shorter than the Canon so it creates an interesting illusion that was pointed out in depth in this video: http://learningcameras.com/reviews/7-lenses/87-sigma-35mm-f14-vs-canon-35mm-f14
