Hi,

I bought this lens to mount on an Intrepid 4x5, the seller keep saying that is Copal 1 but the one i gor from Intrepid is just too loose.

Anybody know the actual copal mount for this lens or how to measure to actually understand which lens board i would need?

Many thanks for your help

Filippo

I bought a Fujinon W S 180/5.6. It's in a Seiko shutter, and the guy in the store warned me that it isn't any of the standard Copal-shutter sizes. I measured the diameter across the threads (at the centre, where it will sit in the board) with a caliper, and it's 46mm. So for mine, a Copal #1 hole (41.6mm?) would be too small.

I have a board, and I will have to make the hole myself. I don't have a drill-press, or drill bits in big sizes like that, but I have drilled lens-boards successfully before by drilling a circle of small holes, then joining the holes with a small file, then filing and sanding (with emery paper wrapped round a piece of dowel) until it's right.

I have owned this lens for a shamefully long time without getting on with this job! Good luck with yours!
