Hi all,
Please accept my apologies if this is a silly question and if I've posted it in the wrong place.
I was thinking about mounting a pinhole into a spare lens board I have. The lens board has (I think) a Copal No. 1 retaining ring on it. I'm a bit unsure about it as it came with the camera when I bought it used. I've measured it and its approximately 39mm.
Would it be possible to screw a 39mm to 52mm filter step-up ring into it (do the threads match)? This would enable me to mounting the pinhole to the inside of the step-up ring and use my 52mm filters on the front. Can anyone help?
