Mount adapter ring for EOS lenses on to classic Olympus penF mount camera

(made of brass/chromed, and aluminum alloy/anodized)

Note: this is mostly suited for Canon full-frame EF lenses. Most of EF-S lenses won't fit due to their rear end protrusion. With Canon EF lenses, you can only use it manually at max. aperture.

Or you can couple this with other legacy lenses to EOS adapters (ex: OM lens to EOS mount adapters, M42 lens to EOS mount adapters, PK-EOS mount adapters, etc.) and use those legacy lenses with your Olympus penF camera
