Don, I also own an "M" 50/1.4 and an "A" 50/1.4.
I found that they are both just about un-usable at f1.4 and I wouldn't try unless I am desperate. However, by the time you get to f2.8 they are both fine and at f4.0 they are the sharpest lenses that I have - I know that I can get great results with portraits at f4.0 to f5.6 on both film and digital.

Both at 1.4, both focused on the mailbox using the in focus indicator, shots within a couple of minutes of each other. Shot just before dusk in indirect light. On the ist-D. JPEG straight from camera, no post processing. Any idea what could be wrong with A? It looks and acts perfect but the image quality below 5.6 hoovers! By 5.6 they're about equal, at 8 and smaller the A wins. :-( http://www.donsauction.com/pdml/A_vs_M.htm Don
