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.

Bought this lens for my Canon EOS haven't taken any pictures with it yet

In my opinion, if you go for the Canon EOS M, you really ought to own both lenses as there are only two native lenses out. While I contemplated buying a lens adapter for the bigger and bulkier pro-style lense, I'm quite pleased with the mix of the 18-55mm and this 22mm. Great at capturing pictures in low light, and the pancake lens with your EOS M really makes it a truly portable DSLR level shooter.

I needed a external flash quick before a wedding I was Photographing! I have the canon eos R5, I didn't wanna pay $300 for the canon brand so I opted for this one. It came super fast. I immediately started playing with it, and absolutely love it. The settings are quick and easy to adjust when shooting, to get the desired effect you want. I am very happy with my purchase!

Every owner of R6, R5 or R camera should have this lenses in their bag. Very small, light weight, and sharp lens. Not an L lens, but very good for the price.

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.

I bought this for my R5. I am a tv director and demand quality. The canon branded one wasn’t available (back ordered till forever) so I took a chance on this one. Absolutely perfect. Tight fit. No wobble. Full functionality of the lens features from my $14,000 prime lens down to my $2000 l series lenses.

This is my first true RF lens for my Canon EOS R5 and I love it! I've been using my beloved EF lenses while renting and saving for the gorgeous but expensive RF lenses like the 85 mm 1.2. I've always wanted a good 35 mm that was sub 2.0, and I've always like macro lenses as well so this fits the bill. It's also pretty compact and light. Usually you can't go into a stadium with the R5 and typical EF or RF lenses because they see the size and think professional camera and they forbid pro cameras. But put the 35 mm on it and they let it slide. It focuses quickly and images are quite sharp. I love the RF 15-35 2.8 lens (rented it for a couple weeks to handle a couple photo shoots). But this lens rivals that lens at 35 mm. It may not beat that lens in absolute image quality but when you factor in the macro feature and how small and light it is and the price this lens comes in at, it deserves a place in your collection.
