    Question Newbie lens board question

    Just bought a Fuji Fujinon W 250 mm f/6.7 lens. I'm assuming, to judge from the diameter of the retaining ring (41 point something mm), that the shutter is Copal #1. (I can't see any number, only the name.)

    Could someone confirm my hunch before I order a lens board?

    Interesting list. Oddly enough, the hole size, despite the heading, is given in inches twice. But 41.6 mm = 1.638 in. So I guess I'll go with #1.

    Many thanks for your help.

    Because we're not making a watch. You merely want a hole that's large enough, but not too large. It's a Copal 1 hole.
