That's not much. More than I have, but I can't forget a conversation with my late friend Charlie Barringer. He had a couple of display cases filled with Contaxes (all IIs, I think, but to me one Contax looks like another), each with a 50/1.5 Sonnar. Several dozen of the things, and more other stuff in closets and cabinets and chests and boxes in the garage and ... I remarked that he had quite a large collection. He then told me about another Zeiss collector who'd bought a house to hold all of his.
