Re: Large format lens
You probably bought junk, but if you're lucky and it has a large image circle, the separation may not cover the film... likesay it's designed for 8x10 and you're shooting 4x5.
I bought some graphic arts (Apo-Nikkors) lenses for cheap and mounted them. They perform beautifully in the studio for product images and art reproduction. You can save a lot of cash on lenses by using a focal plane shutter. It costs as much as a good lens but except for wide angle, you never have to buy another lens mounted in a shutter again.
Separation in a composite element is essentially delamination between two pieces of glass cemented together. It compromises the optical integrity in several ways and probably indicates other problems with the lens as well. On the other hand, you may get some funky effects from the lens, or a perfectly good shutter that can be used with another lens.
What did you buy?
