Les, here's the thing. I often see this kind of question asked. It goes something like this: "Hi, my name is ______, and I am a long time Nikon user. I have always wanted to try an Olympus camera and I bought an OM-4T. I could never really get used to it because the shutter speed setting around the lens mount was wrong and the control layout was different and the lenses focused backwards. I never really got along with the camera and ended up selling it."
