Can a RF645 user check the distance between the film plate and the front of the lens flange? Couldn't find the info online. Might be tricky to measure because of the baffle? Thanks in advance.

You were correct in it being a challenge. I get 43.92mm but not with confidence. I have a vague recall of a schematic in one of their catalog/fliers?

Thank you! I just needed a ballpark. That is quite a short distance for a MF camera but it should work. Planning to adapt the 45mm on a DIY build. Will the cells fit on a mechanical #00 shutter? I'll find out once I get it. The ETR lenses do fit on #0 shutters so there is hope.

The answer is no. This RF645 lens has a custom arrangement to attach the optical groups.
