| Comments | Fast wideangle prime. Can also be used a a "normal" lens on a crop sensor DSLR where it has the same FOV as a 45mm lens would have on full frame. A big advantage it has over some competitors (like the Sigma 30/1.4 for APS-C) is that it has fast, accurate (and quiet) AF via its ring USM motor |
