I agree, the Skopar is definitely sharp. The Bessa RF models tend to be lower priced compared to the Bessa II cameras, but the optics are the same except for the lens coatings. The Heliar on the one below had no coatings at all, and uncoated lenses are my favorite for B&W. These cameras are of a very high quality.
This one had a rare 6x6 mask, and you could actually change the camera's viewfinder to that, but it was more trouble than it was worth. If I wanted 6x6 there were better, smaller cameras for that. I remember having a small Bessa 66 w/ what I think was a 75mm Heliar.
All the smaller Voigtlander Heliars seem to image the same no matter what their focal length. I don't know about the LF lenses, I never had that much money to invest in a lens. One could buy a nice mobile home for what those things cost.
