I've got the Oly 50 f/2.0 macro, and love it for what it does well. But I rarely reach for it, bcs much of the time my subject is a fast-moving rug rat, or furball that doesn't give the 50/2 enough time to focus.

Love the 50mm focal length on the 4/3rds bodies for portraits, though. I can live w/o ridiculously biting sharpness since most of the time the corners are nothing but beautiful creamy OOF backgrounds. So...Looking at options...

Has anyone here had both the Sigma 50mm f/1.4 & Oly 50mm f/2.0 in their hands at the same time & compared the handling? How snappy is the handling on the Sigma relative to the Olympus 50/2.0?
