I'd say that's probably generally true. > However, the 1.2 is very expensive and probably not worth the > extra money for most shooters. The 50/1.2 is worth it if you do sometimes need the speed (not just for low-light exposures but also for low-light focusing). It (both inK and A trim) is not as sharp as are many of the other 50's at wider apertures (except wider than f/1.4 - <g>), but it is very sharp at mid-apertures. Fred
