I've never used the 50 f/1.2, but from what I understand, it is corrected differently than most lenses (including the 50mm f/1.4). It is figured in such a way that sharpness is compromised in exchange for a particularly smooth bokeh. Look at Bryan's review for sample photos: IMO it really looks nice. However, as others have said, sharpness suffers as a result.


Before buying the 50 f/1.2, you should know what you're giving up with this type of correction and what you're getting in return.
