Review on Fotodiox Pro Lens Mount Adapter With Auto-Exposure, Auto-Focus And Auto-Aperture, Canon EOS EF EFs Lens To EOS M EF-M Camera Body by Christopher Smith

I purchased this adapter to connect my Canon DSLR EF-M lenses to a Canon C Mount Canon EOS-M. Needed an adapter that would work with the full electronics of the EF-M lens. This has worked great without any problems. It controls the auto-focus, the zoom and aperture without any issues. It does look funny with my 18-55 lens on the little mirrorless camera (see attached picture). I also tried this using a non-Canon lens that was EF-M 18-135mm and it worked without any issues. I love that it includes the tripod adapted on the bottom. I would recommend connecting to your lens first, then connecting the adapter to your camera. There's a little slide button on the side when you need to remove your lens. I would purchase again if needed.
