Two questions for all of you: What? Why? The late Charlie Barringer once asked me very pointedly how I justified buying the lenses I did. Charlie was a serious collector of Zeiss artifacts and what he characterized as extreme lenses. His rationale for collecting was to be able to add to knowledge. And he did. Charlie and his friend M. J. Small wrote a book, The Zeiss-Ikon Compendium, which was published by Hove. He was one of the founders of Zeiss Historica, a Zeiss fan club, and published many articles explaining Zeiss products in the club’s magazine. He bought his extreme lenses, e.g., a 44/5.6 Super Aviogon, because having them pleased him. I bought most of the lenses that puzzled Charlie because they could be used on my 2x3 Graphics, were good, and were quite inexpensive for what they did. In the case of poorly- or undocumented macro lenses, to find out which were fit for use and, again, because they were quite inexpensive. Boyer lenses because what documentation could be found on them was confusing and because they were very inexpensive; finding out what they were required buying them. So there’s my “why” and my “what.” Good and relatively inexpensive lenses to use, mainly, on my 2x3 cameras, with a whiff of adding to knowledge. I pursued lenses made by the French firm Boyer and eventually published, with Eric Beltrando, an account of the firm and its products on the French large format site. Now, what do you accumulate? Why do you accumulate it? If you accumulate cameras and not lenses, why not? Re what, I’m not asking for an inventory, I’m asking you to answer at a higher level of abstraction than a list.
