This lens is soft wide-open with lots of CAs at f/1.8, but stopping down to f/2.2 eliminates most of the problems. It becomes very sharp after f/2.8 and offers very nice smooth bokeh.rnrnOverall, it is an excellent and affordable portrait lens.
This is one of the sharpest FD lenses I've encountered in the FD range. I'm finding image quality to be on par with my FDn50mm f1.4, and at least good as the latest EF version of this lens which I owned previously.
Using it currently with the Sony Nex 5n as a short throw portrait lens.
