Fotasy Canon FD FL Lens to Canon EOS M EF-M Mirrorless Camera Adapter, fits Canon M1, M2, M3 M10 Mirrorless Camera

Solid metal construction coupled with nice machining lends this to be a very solid mount. No play at all when assembled.

It’s a bit finicky with the aperture lock but this thing was so cheap I solved that by buying another so I can leave them on my lenses, built tough, only criticism is that it didn’t come with a rear lens cap for the EOS-M side, again cheap so I bought a two pack.

Works as intended, allows for closing the aperture

This is a simple, sturdy adapter. Very impressed. My old FD lenses fit well. As others have pointed out, you have to set a custom setting in the camera to trigger the shutter "without lens" as there is no communication between the body and lens; nor for AF or aperture. The "Lock-Open" ring allows you to easily, in one, short turn switch between full-open iris (for focusing) and stopped-down for metering and exposure. My old Canon 28mm 2.8FD and Vivitar 70-210 3.8 both fit snug and solid. Where's my 50mm 1.8??? Very hard to focus on the live view screen without using the zoom feature, and you have to un-zoom to take a picture. But it does allow focus to infinity just fine. Can see using almost exclusively for tripod-supported photos and video. But for the low price this is a great buy to give new life to my old lenses. And I'm already looking out for some cheap deals to create a set of fast prime lenses for video.

Bottom line first: fits wonderfully, great lockup, no wobble, jiggle, rattle, etc. Old manual FD lens works perfectly. I've used lens adapters before which can't allow the lens to focus to infinity. Not a problem on the EOS-M. Since it's mirrorless, the lens can be mounted extremely close to the sensor, and the EF-M mount does exactly that. Any SLR lens has to clear the swinging mirror, and are thus mounted much further away. This means an SLR lens on a mirrorless camera can be positioned perfectly even when additional metal is added between the body and lens. This adapter pulls it off flawlessly, at least in my case. I'm using an old 50mm f/1.8 FD lens from Canon I pilfered from my Mom's old 35mm SLR, and getting beautiful images. After using kit lenses for so long, I've forgotten what an f/1.8 depth of field looked like! When I used a cheap Olympus lens and adapter on my Canon T3i, it jiggled and wobbled so much, I ended up having to secure the adapter and lens together with silicone adhesive. Not this combination -- the three elements fit together like Canon made it all themselves. Well, they made the body and the lens (albeit 30 years apart), but Fotasy played their part admirably.
