I am always surprised when people make a statement that SR compensates for the lack of a faster lens (or for not using a flash). SR can be useful, but only when the subject itself doesn't move. When the subject moves, - you want to have exposure time to freeze the motion, and that's when fast lenses are helpful (or a flash, depending on the circumstances). And that's why Larry is pulling out his 50/1.4. I find myself using my fa50/1.4 under the same circumstances, and using 50-135 at other times (for 50mm focal distance), when I am not lazy to switch to it from 17-70/4. Extremely subjectively (no tests whatsoever), - my impression of the sharpness of my fa50/1.4 is similar to Larry's. I tend to blame it on how I use the lens: because I always tend to push it to f/1.4 where it's softer and the DOF is shallow. Additionally, usually the ISO at that point is also set to at least 800 if not 1600-3200. Hence, the combination of all these factors lowers the expectation.
