Hello there,

I know there might be threads about this, but I could not find any with a proper answer.

I've recently purchased a Rodenstock W 150mm f5.6 mounted on Prontor Professional 1, which I don't really like. I also have a spare almost mint modern Copal 1 shutter and I'd like to mount the lens on this shutter.

Does the lens need calibration for aperture scale?

Many thanks!
