so I impulse-purchased this Symmar 240/5.6 "Convertible" (great for summer, I thought ) for a few thousand today. Comes with a bit of Schneideritis and some fog, but that's OK.
But it is mounted on this Sinar board. How can I get it off there (no retaining ring on the back) and what size shutter am I looking for? The shop said it needs to be custom-drilled, but are the Compur sizes that non-standard?
Thanks for advice
