this is my second EF 50mm lens. My first one is has the plastic mount. This one is much quieter and auto focus faster

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.

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 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.

Definitely a good lens, probably use it more than telephoto lenses.

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 would recommend this lens to people who just starting photographyIt's not as expensive as some of the other prime lens for EF-M mount

Great adapter, must have. Can't beat the price and works perfect. Allows you to use way more lens on your ef-m mount camera.
