I use this with my Canon M50 so I can use my older EF and EF-S lenses. It works great with both! The autofocus features on my lenses work the same way they did on my previous Canon. Very happy with this adapter.

I am in no way a professional photographer, but let me tell you, this lens is amazing! I've done so much research and come to find out there aren't many options for the ef-m lens mount, especially to zoom. So i decided to give this one a try and boy am i glad i did. I mean ofcourse unless you want to get the Ef / Ef-s lens adapter.To start off, im using it on a Canon M50 mark II. Yes i know, it's basically the M50 with a new name but honestly it doesn't affect me much, it's the first new camera I've had in YEARS and it works awesome! Second, you will need to make the shutter speed lower and turn off continuous AF and trust me, this will fix all the blurry picture issues. I understand 200mm isn't that far as you would like for wildlife that is pretty dangerous to get really close to but it does its job in regards to animals at zoos or just around your house.The seller was awesome aswell!! I ordered the lens on a Monday morning and had it in my hands by Thursday!! Keep in mind it crossed the whole country and with the pandemic going on it really is a bonus. The description said it was new and was part of a set that didn't sell together, i saved at least $100 for a NEW lens and could not be happier.

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

Works great when using EF lenses for my Canon M50.

It is pretty helpful to mount any EF lens with my Canon M50 and there is no change in Auto focus and image stabilization which is too good...

I used the EOS-M adapter to put EF-S lenses on my Canon M50 Mark II. Adapter fits well, everything on the lens works as if it was a regular EF-M lens. I especially like the tripod mount for those particular large lenses to keep the whole setup balanced.Used a 55-250mm EF-S telephoto lens to compliment the 15-45mm included kit lens. Really feels and shoots like a whole new camera and allows a huge range of EF-S lenses to be used. The adapter is good quality, the finish does not exactly match the Canon finish, but it looks good.

I bought this for my m50 camera so I could use ef and efs lens.I attached it to a canon ef 70-300 telephoto lens and as soon as I turned the camera on it started autofocusing before I even press the shutter button.After watching froknowsphoto on you tube, I went into my cameras settings and turned off continuous autofocus. Now it works great on all of the ef and efs lenses I have.

Perfect to keep my existing collection of EF-S lenses to use on my new mirrorless Canon M50. Be aware that if you’re switching to the newer camera, it is smaller than what you’re used to. There is a tripod bracket ON THE ADAPTER because the center of gravity has now shifted away from the (smaller) camera body. But it works beautifully and helps preserves your investment in glass - so I recommend it!
