K&F M12121 Canon EF Lenses to M43 MFT Lens Mount Adapter
Works exactly how it described. Nothing more.
Does what it’s supposed to do. If you’re looking to mount your canon to a panasonic/olympus body with no features whatsoever, then this is right for you. figured out it didn’t work with my 50mm f1.8 canon stm lens because there wasn’t a connection between the camera and lens. no auto focus and the manual focus on the 50mm f1.8 didn’t even work. in conclusion, spend the $200 and get something that actually allows you to use your lenses to their full potential. unless you’re a manual focus kinda guy/gal (manual focus works with most other lenses.)
