I don't post very often, so if i offend anyone by being repetitive it's not entirely my fault ha, but i'm in the process of building a 35 adapter and i was wondering if anyone knows of a supplier of a bayonet to attach the lens to, similar to the one century optics uses.
I think a lot of people that build DIY adapters scavenge the mounts from broken camera bodies, although you should also be able to use macro extension tubes or teleconverters too -- anything that would go between a lens and the camera body.
