Canon EF -> Olympus Pen Adapter lens mount_Canon EF-S and it really feels likeDo you want to mount a Canon EF lens to your Olympus Pen camera? Not the Micro Four Thirds Pen, the original half frame film Pen, the one from 1963. Worth noting: because EF lenses generally have an electronically controlled diaphragm, and this is an unpowered adapter, you won't have any aperture control. If that doesn't concern you, have at it. In excellent condition.
