I tested my Screw 55/1.8, A50/1.7, A50/1.4 and A50/1.2 lenses then other day and I my assessment is similar to most peoples WRT sharpness. However that factor is far outweighed in my opinion by the variation in rendition due to the differences in the lenses characteristics. I found even at mid-range apertures each of the lenses have their own image characteristics which are most visible at the edges of the frame. Each is good for particular uses, I find it so strange that people seem to dismiss the A50/1.2 on the basis that it's not as "good" wide open as a A50/2 or A50/1.7. Sure it's different but still highly usable as photographic tool. I will try to get some sample images up to show what I mean next week.
