Fits for Minolta SR/MC/MD Lens To Leica M and 50 similar items

The creator is ProfHankD Minolta used to be one of the more popular brands of 135 film SLRs and lenses. In fact, they were one of the very few lensmakers making their own glass, and their lenses are well known for exceptionally consistent color -- they famously even made some lenses for Leica. Minolta introduced their SR bayonet lens mount in 1958 and, with minor variants labeled MC and MD, continued producing lenses in that manual-focus mount until 2001. (Do not confuse these with the incompatible Minolta autofocus lens mount, A, which began with the Maxxum line in 1985 and has been continued by Sony since 2006.) Because SR has a relatively short flange distance, there were not many adapters to mount SR lenses on other bodies, but adapters to various mirrorless mounts, including Leica M, are commercially available. Ok, so why 3D print this one? Because we can seems like a decent answer -- this is an easy print in 2 pieces: the adapter and a removable lens locking pin. However, an SR to M adapter allows the latest Sony E mount bodies to autofocus these manual lenses via the Techart Pro LM-EA7 adapter... which has a 700g weight drive limit, so we don't want to waste weight on a heavy adapter (this one weighs about 11g). There is also a potential issue in that some SR adapters -- but not this one -- are too thick on the M side to fit on the LM-EA7.
