gee Matt. With a bum right hand this might be the perfect camera. You can focus either by turning the lens ring or that little knob to the left of the lens. They stiffen up usually so a CLA might be in order to use the little focus ring but it'd be great if working properly. Of course you'd have to support the camera with your right hand while focussing with the left. And these are heavy cameras. Hmmm, maybe not a good choice?
I'd try and get a Medalist II. There is a problem with the shutter lock on the earlier model that is fixed with the II.
I had one of these and like everyone else wish I had'nt sold it.
