I'm somewhat torn between deciding which are better. Right now I have Pentax 50mm/1.7 A lens and a 28mm/2.8 A lens as well. In Olympus-land, I have the 50mm/1.4 G.Zuiko and a 28mm/2.8. I'm convinced that the Olympus wide-angle is better than the Pentax wide-angle which goes soft fast in the corners at large apertures. But I'm starting to think the 50mm Olympus lens is pretty soft wide-open and is very prone to flair. Which brand do you think has the best manual-focus lens, especially the best fast normal lenses? I like both my Pentax and Olympus bodies, but I like the olympus body a bit more.
