This adapter works well with my EOS M50 and a Tamron 150-600 G2 lens. The combination has allowed me to use My M50 for bird photography. The adapter has opened up a new world of EF lenses. I fancy the Sigma 105mm macro lens.

If you are a EOS user with a range of lenses this adapter is perfect as they fit on the tiny EOS M3 body. There is a tripod mount in the adapter which takes any stress off the body.If you are a full frame user the lenses will have the appropriate factor re: the focal length.

It really is a no brainer getting this little attachment to add other 'professional'lenses. It gives you the flexibility to use your camera in more scenarios. Only 'downside' is the sheer weight of professional lenses in comparison to the light weight body of your camera.

This is an unusual bit of kit for these days. It only does one job and it does that one job to perfection. The tripod thread is definitely needed when you hang a 300 mm lens on the front of the tiny EOS M camera

Use this to enable EOS M3 to use your range of canon lenses. Easy to fit does what it says on the tin. No issues with the product identified. A pleasure to use.

"The DSLR lenses are a bit quite a bit bigger than the equivalent EF-M lenses, but it's great to be able to use them in special situations. The adapter is ruggedly built with a removable tripod mount. I've used it with a macro lens and an older 100mm to 300mm zoom with great results.

Awesome for my M6

Enables you to use your existing EF lenses with the M3.

Were it not for this little piece of kit, which I bought as part of a bundle, it is unlikely that I would have bought an EOS M3. The reason is that I wanted a small, lightweight camera that I could attach my EF lenses to and the adapter allows me to do just that.

Great if you have EF/EF-S/FDn etc

Perfect, just what I needed to use all my old EFS lenses.
