somewhat releated to the above, however, I'm abou to engage in a little thread hijacking.. Does anyone know where to get a good optical diagram of a classic lens*? This includes the elements/groups, but also the lines indicating what path the light takes through the lens? I found one of these, once, that would totally meet my demands**, but it was too small and I couldn't scale it up cleanly to meet my requirements. I even went so far as to try some software that was supposed to turn them out, but nothing really worked how I wanted it. Unfortuantly, I can't find the original gif that I liked. It must be on my girlfriend's computer. If you think you can help, let me know, and I'll show you what I'm looking for with that example. * - Ideally, I wanted to find a Zeiss tessar. The one I found appears to be a Zeiss planar 80/2.8, which also worked. A Pentax 50/1.4 would also be swell, but at this point, almost anything would work well (except, well, I really would love it tto be something truly classic, like those Zeiss lenses). ** - It needs to be complex enough to be interesting, but not so much that theres TOO much. A straight up optical formula is kinda boring. Its the l ines that abstract it and make it interesting. There was a point when Hassleblad designers were posting to rec.photo.equipment.medium-format. I meant to hit them up witrh the same request, but never did, and now it appears they've vanished. -- http://www.infotainment.org <-> more fun than a poke in your eye. http://www.eighteenpercent.com <-> photography and portfolio.
