hi
i recently purchase a carl zeiss jena ddr tessar f4.5 / 360mm.
it is a heavy lens
i want to get a flange for it.
i am not sure how to determine the threading
does anyone know if this is metric or us imperial?
the back diameter circle of the lens is 4.25 inches
would it be better to get a mounting flange or mounting retainer / ring?
any help would be appreciated
thanks
phil
