What can I say! It's a Canon body cap that will fit any canon camera with EF anf EF-S mount, doesn't matter if it's a full frame, APS-C, or film. In other words, if your camera was made in the last 30 years, this cap will fit!

Not much to say here, this device allows you to mount an EF lens onto your EOS-M camera, and appears to be well built. Done.

I have a Canon EOS 60D with a stock EF-S 18-135 IS zoom lens and had yet to purchase any additional lenses before buying this one. I am a hobbyist and and amateur where photography is concerned, so I can't speak to all of the details of why this is a great lens, but I can attest to the beauty of the images that this lens captures. Beautiful detail, gorgeous depth of field and really pleasing "bokeh" that really does seem to elevate my photos. I am so glad I added this lens to my kit!

Purchased this for my Canon EOS camera so that I can use the Canon 50mm EF lens. Easy to use and no loss in function. I recommend for anyone who wants to use an EF lens with an EOS.

So you finally decided on getting the EOS M (it's flaws considered). I assume you are a canon user, have a couple of good (canon EF/EF-S mount) lens lying around and would like to be able to use those on you EOS M. Just like me, you love your canon dslr but sometimes wish you can travel light but still be able to enjoy the canon ecosystem that you have grown to love. If you are what I assume you are, get this lens adapter.I took a gamble and bought a "like-new" used from a seller at Amazon and was very happy with a purchase. For anything more than $150 I probably would think twice. But I am not taking a start out because of the price. This adapter handles every canon mount lens I threw at it. The build quality is nice. The design (the way it attaches to the eos m; the included, detachable tripod mount) is well thought of... just perfect.

Canon EOS M Mount adapter is a must have for all Canon EOS M users if they have other Canon EF and EF-S lenses. The construction is solid and heavy. I used several Canon EF-S and EF lenses and they work fine with the adapter. Highly recommended.

Exactly what I needed to use the Canon EF 50mm lens with my Canon EOS M50!

I always bought old used cameras and splurged for a brand new camera the Canon EOS R6! Coming from an old 2012 Canon 6D this is spectacular! I feel a little dumb because there are all these new features, im getting a hang of it! The picture quality is insane and I don't have any RF Lenses yet... I bought the ef adapter and using an ef lens and the quality is still incredible! I recommend this! Mirrorless is the future and i'm glad I finally got onboard the train!
