Just starting with Alpa 12 medium format camera. Noticed that front element of the Alpagon lenses (Alpa's version of Rodenstock Digarons) would touch screw in filter such as BW slim circular polarizers.
I ended up getting step up rings from Polar Pro Filter, Inc. I would use larger filters then lens front threads - works great. Step up ring pushes filter out by 2 mm or so.
This solution brought up new issue - cannot really attach neither original Alpa lens shades nor Cambo AC-324 shade (which I prefer). Both of those filter systems use front edge of the lens as a "stop point".
What other people do?
