Come on...nobody ever asks how much the bellow of a Bessa-II 6x9, the pride of the German camera industry of the early 1950's obscures the finder -- but with the 0.95 this is always the first question to ask. Actually the Bessa-II masks about 1/3, while a 0.95/50 mounted at a Canon-7 masks about 20%, and it's finder is much clearer and more precise. In addition, you don't have a choice of lenses at a Bessa 6x9 - you have to live with!
Canon produced a series of 50mm lumi-finders then, but I never seen one in ebay.
