I have purchased this lens for 4x5 out of curiosity. It is a 500-1000 variable lens, probably at least 50 years old. I thought it would screw directly into a Copal 1, but it doesn't. An adapting ring will probably cost more than the lens itself, so before I get into spending more money, has anyone tested the lens in the long range (750-1000mm)? Is it worth the effort? If someone would have a table for the numbers engraved on the barrel, for the corresponding focal length and openings, this would be most welcome! Thanks!
