Would it be even remotely possible to get these to work with crop mode on the GH2, or am I dreaming? I know C-mount lenses work, and even with those, only some lenses work without vignette. the 8mm (D mount?) lenses I would guess have a shorter flange distance and a smaller image circle even compared to C-mount? Anyone tried this (or anyone know that its not possible)?
Bolex used a c-mount with an added electrical interface in later models. It should work, however you may need to hack the lens adapter or even the lens to fit an adapter.
