This Canon f0.95 lens is the scarce "TV" version. This is identical optically to the normal version for the Canon 7 rangefinder camera however it does not have a rangefinder coupling so the rear element is circular and complete. Likely this will give a slight optical advantage over the normal rangefinder coupled version when adapting this lens to mirrorless digital cameras.  Adapters for Canon RF, Nikon Z, Leica L, Fujifilm X and Sony mounts are available online for around A$100.  It cannot be mounted on a Leica M or LTM type camera.   This example is 99% like new.  Includes a C mount adapter for use on movie cameras too.
