Ykeasu EF-EOS M Auto Focus Mount Adapter Weather Sealing, Fits for Canon EF/EF-S Lens to Canon EOS M Cameras Include EOS M1 M2 M3 M5 M6 M10 M50 M100

I was initially hesitated to order this adapter due to its unfamiliar name brand. Its on sale, so I took the risk, thinking that if it did't work at least i could return it. To my surprise, it is very well made, fit and function perfectly on my Canon EOS m50 mark ii. I tested with two ef-s lenses, including the ef-s 24/f2.8 and 18-135/f3.5-5.6. The autofocus is fast and spot on. I have no issue with this adapter, Highly recommended.

I have the Canon EF-R adapter, and I thought I'd try this EF-R adapter as it was significantly cheaper than Canon's. I'm glad I did. I find no difference in terms of AF speed or accuracy, or any other functionalities when compared to Canon's. Build quality seems just as good as Canon's as well. What I like about this adapter compared to other third-party ones I looked into is that it has baffles to reduce light reflection, just like Canon's.

I have recently purchased the newly released canon Eos R10. After attaching this adapter which locks right in tightly no movement with my ef sigma art 18-55mm lens. All data reads perfectly with canon’s new focus system and something new to me where the camera shows the actual live focal range, confirming no issues!

This adapter does what it advertised, conducting all the signals between the EF lens and RF camera. However, it does not fit snugly; there is some play (wiggle room) in the mount. Not sure if this will create a problem or not.

Fue de los pocos que funciona bien con lentes canon ef, efs y yongnuo. No recomiendo los commlite, no funcionan con otros lentes que no son canon.

My camera stopped working while shooting using this product with my 300mm telephoto. Thought it was the camera but after I removed it everything worked fine. re-attached it and camera once again stopped shooting.

Does exactly what it is supposed to. Haven't noticed any loss in quality while using and auto focus is on point.

Works exactly as advertised. It fits on the camera (Canon RP) completely snug with no wiggle. Have had no problems with it in the last month of owning it.

Función très bien avec mes lentilles EF-S. La conexión est excellent.

Feels, looks and works as expected. Solid build. light. Absolutely no issues at the best price for this particular solution of Eos M to EF.

Good quality of adaptor. Solid metal but not too heavy.

Good quality! Even better than expected
