As a long time OM system owner and film user I am now starting to look for a digital SLR. I'm a bit confused by all the talk on the differences in sensors between the big two and Olympus. What I want to know is does Olympus match it with Nikon and Canon in image quality and sharpness? All the pics on screen seem a little soft to me. Are the actual prints sharper? Also, does anyone use their old OM lenses in an Olympus DSLR with the adaptor? Is it hard to focus and what is image quality like? What would be a good lens to get for the E620 for portrait and travel work?
