hello.
i bought this lens (sn 490101) in black barrel in great condition.
cells threads equally sized, back cell would fit copal 1 but cell thread cannot 'reach' shutter thread, front cell too small in diameter .
is this version not a fit and cant be mounted like dan fromm stated? is my version not modern enough?
regards,
chris
Chris, Boyer published mechanical specifications and made lenses that didn't meet them. My 180/6.8 Beryl's cells meet the specs and are direct fits in a #1 but as you've learned some don't.
I don't think it is a question of age, more likely it is one of the customer for whom the lens was made.
If you want to use the lens, the best option is probably a cup-shaped adapter that will hold it in front of a shutter. If you hang it in front of a small, e.g., #1, shutter vignetting may be a problem because the lens will have to be some distance in front of the shutter. When I went up to 6x12 I had this problem with my 210/7.7 Beryl S, solved it by putting my 210/6.8 Beryl's cells in shutter. The -S' cells won't go in any shutter I'm aware of.
hello dan!
thank you for your reply.
in this casre i will return it, as i have quite a few barrel lenses i am not using enough and as i work with 5x7 loosing ic by frontmounting is not an option.
regards,
chris
