On EBay there is an offer for a f4.5, 300mm lens in a Copal 3 shutter.
The outside diameter of the shutter is 100mm
The lens board on my Calumet CC401 is 100 x 100mm
Obviously the shutter cannot be connected directly to the lens board
BUT could a spacer be placed between the front of the lens board and the back of the shutter?
If what, if any, would be the functional disadvantages/problems?

regards

Tony
