I have seen shots from that Mamiya on Flickr that look to have excellent image quality. The lens should be quite similar to the two cameras that I mentioned above, as well as most other compact rangefinders of the same vintage. "A range finder with point and shoot quality"? What does that even mean? There are many point and shoot cameras with lenses that are of very high quality. Did the camera makers forget how to make good optics when they added automation, or something?
