Something I picked up earlier this year - a Russian half-frame camera with interchangeable L39-mount lens. Unfortunately you can't use the lens on Leicas etc. because (a) it's pretty crappy and (b) the back focus distance is about 1.3mm less than the normal Leica mount. Shame, because it's an amazingly compact lens. It would be fairly easy to adapt them to a micro 4/3 or NEX mirrorless camera by grinding or cutting a little off the adapter. Don't have any test pictures because the lens was damaged a little, and I sold it on fairly quickly. It's a pity, because it felt like a fun camera. If I get another with a better lens I will get an adapter 3D printed by a friend who can tweak things like the back distance.
