Have (as I'm sure most) no comparison to the Canon original adapter, which costs about 2-3x as much. The adapter works as expected for me in connection with a CANON EOS M100 and a Canon EF-S 55-250mm, I don't know what the original should be able to do better. Autofocus seems slower than with the EF-M standard 15-45 kit lens, but is sufficient for my needs. Covered the range from 15-250 inexpensively. Can't imagine that I noticeably miss the missing range between 45-55. Snaps in perfectly on both sides, sits firmly without misaligning in any way. It seems to me that it is built a little unnecessarily too deep, but I don't know whether the distance has to be like that for optical-physical reasons?

Wonderful to be able to use my old FD lenses on the Canon RF. Even the manual iris setting works as it should.

The adapter keeps what it promises. The autofocus works very well and the quality is really good for this price. The adapter can be mounted on my camera (canon eos m 100) without any problems. I'm very satisfied!

The adapter is processed very valuable. Fits perfectly to the Canon R. A Minolta MC Rokkor 1:1.7 55mm can be operated without any problems

especially at the price!!! Works and fits great on the EOS M3! Lenses I was able to test: Canon EF 50mm 1.8 II Canon EF 70-200mm 4.0 L IS USM Canon EF-S 15-85mm 3.5-5.6 IS USM Sigma EF 10-20mm 4-5.6 DC HSM These four lenses all work with AF or .Image stabilization, if available. Unfortunately, the Tamron 90mm 2.8 macro USD Di VC SP may not send the AF and image stabilizer, so it only works manually, but delivers suuuuper image quality! In the end, that doesn't bother me either, since manual settings are best for macro photography anyway if you want to get a decent picture. ;-)

This adapter does the same job as the original Canon ef/ef-s to eos-m adapter. It is just a structural adapter that has no functionality of its own. I can absolutely recommend it. If you're on a budget buy this or even if you're not on a budget buy this and the extra money for a lens or other gear.

I'm very satisfied, it's valuable and does 100% what it's supposed to do, the adapter....

I've only used the adapter three times so far and I've always been surprised at how well the adapter works. Attaching and detaching to the camera works without any problems. The adapter sits firmly between the camera and lens. All my lenses, except my Canon L100-400, work without any problems. The L100-400 is too big for the M50. Focusing also takes a long time. But I didn't plan this lens on the small camera either, so no deduction. The adapter only eliminates the difference caused by the lack of the mirror. It has no optical and therefore no quality-changing elements. The autofocus is looped through and works very well.

I have a few of those from K and F... Everything was always great. Like now. Works perfect.
