Is this lens magical? I've heard many great things about the Heliar bokeh on the Bessa RF/II and also on the Kodak Medalist. The Mamiya Sekor 105/f3.5 D/DS lensis supposed to be a Heliar design but I don't hear much about it. 1) Is the bokeh distinctive? in comparison to the 80mm f/2.8 2) Does this lens render the image similarly to other Heliar designs?
