480mm-600mm barrel lenses, covers 14x17 wide open, faster than f9?

Ah, never mind. I found the site. Thank you.

Good.

I have two of his lenses, a 500mm I use on 11x14 and a 285 that I use on my 8x10.

Working with the Wollaston Meniscus lenses is a bit different than working with your typical Tessar or Dialyte but I enjoy using them. You can certainly make them for yourself, they really are not that complex, but Reinhold does a great job with them so I don't mind parting with the funds for his work.

He doesn't work with Paypal so it takes a check or a money order but I certainly don't mind that.

How about a Beseler lens from one of their opaque/overhead (forget which) projectors. Many years ago I sold my 14x17 film holders (medical ones) to a photographer in the Boston area who used one of these lenses on his 14x17. I picked up a 14" one that I intend to experiment with on my 11x14. No aperture listed on the lens, but f/4.5 sticks in my mind for some reason. In the late 1970s used a Beseler projector that probably had a 500-600mm lens on it and had to be easily in the f/5.6 range.

I don't really know . . .just brain-storming . . .

Do any of the HUGE Petzval lenses I see on e-Bay meet any f your requirements. I think some might cover enough and some would be fast enough . . .

I think Giles Clement uses a 500mm 4.5 Goerz Dogmar for his 16X20" plates
