I have a recently purchased a Kowa 150mm f9 lens in barrel which I am going to mount in a Copal 1 shutter. The lens in barrel was mounted with a thin spacer, approximately .4mm thick. The lens also came with another spacer, approximately .83mm thick, in the original box. Can somone who has this lens mounted in a shutter tell me if it has either, both, or neither spacer used with the shutter? A very quick visual test appears to favor the thicker spacer alone, but it is really too close to call.
