Got one because I wanted to. Mounted on my E-PL5, since I bought an E-M5 recently. I figured I would just leave that as the dedicated Fish-Eye/Super wide camera, and use the E-M5 for everything else. I was very unhappy with my results, everything just looked soft. I did the thing with the rear element to get correct focus, but still my shots looked, well, fuzzy. Just for S&G I put the lens on my E-M5 and there was a big, big difference in quality. Not perfect, but actually acceptable. Same settings, except I forgot to set the IBIS for 8mm. Hmmm… Put the lens back on the E-PL5, shut off IBIS and Holy Crap!! The lens is sharp as the proverbial tack. It looks like the IBIS was confused, even set for 8mm. Listen, with a 7.5mm lens, I don't need IBIS, so there it is. I'm happy once again. P.
