I have a whopper lens on the drawing board and need some idea of the market potential for it.
Lensboard size is one of the parameters that I need to take into consideration.
So far, it looks like the 171mm (6.7") Arca-Swiss is the smallest size I can fit without modification to the lens mount.
I'm hoping I can come up with an special adaptation to fit the 158mm (6.22") Toyo/Cambo/Omega size board.
żż Am I going into lensboard manufacture??. Not really. I make lensboards to support my Meniscus lens sales, but that's about the extent of it. The Grimes site lists a bazillion different boards, it's too easy to bump into "incompatabilities" with all those variations.
