Adapting projector lenses
Projector lenses are quite fun to use, but with no focusing part, they are a bit difficult to handle.
My lens (a Liesegang Sankar 85mm f/2.5) has a nice long flange distance, which gives me some room betweeen the lens body and the camera mount to place an M42-E adapter, the lens is niclely fitted in a M42-flat ring (then screwed on the adapter). That M42-E adapter includes a focusing helicoid wich makes focusing then possible ! I can still add extension tubes if the minimal flange distance is still too short (I actually have one here).
It goes without saying that using a mirrorless camera makes everything a lot simpler because you have a short flange distance to begin with, much shorter than most of the 35mm film projector lenses (except if their body extends far behind the actual rear element...).
