What Customers Are Saying
Users report that the lens adapter integrates well, especially with Canon 50mm lenses, and they value its sturdy construction and cost-effectiveness. The autofocus features function effectively, with users observing that it adeptly maintains focus on faces, and they appreciate its compatibility with Canon M50 cameras. Nevertheless, feedback on the connection is variable; multiple users have mentioned issues with the electronic link with the lens, and there are concerns regarding the loosening of the mount over time on the EF side.

Great low cost alternative
Like many of you, I spend considerable time researching before I buy an item. I was torn between this adapter and the Canon one for my new Canon M6 camera, which was purchased for a trip of a lifetime. The reviews swayed me, and I put it through a bit of testing today.First, the lock-up between the adapter and camera is solid, and has no wobbling like purchasers of other brands reported. Solid and stable. Connecting several of my EF lenses, both Canon and Tamron, all yielded great quick auto-focus and stable lockup. I took several dozen pictures from varying distances, and all yielded very acceptable results.The lenses search a bit more connected to the adapter when using automatic focusing and the automatic camera setting than on my 5D Mark II, or using a native EF-M mounted lens on this camera, but I rarely use automatic anyway. Further, even though they searched, it was a quick focus when I kept the camera and lens stable. More than acceptable to catch a quick picture that simply can’t be duplicated.I can’t speak to the long term durability, but it has a solid build, and was well packaged unlike many off brand purchases I have made in the past. I have confidence in this. Enough that I’m flying half-way around the world and taking pictures in a place I’ll likely never return to in my lifetime.Well done to the manufacturer, and I can solidly recommend this for your use. I paid full price, and would again.

Gotta work!
My old (1987) Canon EOS has wonderful lenses that I didn’t want to give up. The adapter answered any questions I had about not being able to use them. Arrived quickly, fit very easily and well and was well priced.What else could I wish….

EXCELLENT quality and value
This adapter is built like a tank and works perfectly on my Canon M50 with EF lenses. I’ve also tried it with an EF-S lens, and while it functions OK, the auto focus seems to constantly be searching for the right focal point. I tried it on several settings and turned off the continuous autofocus in the M50 body, but the lens still constantly tries to adjust focus. If I switch to manual focus, the works perfectly. Ironically, the best performance I’ve had is with my oldest lens — an 75-300 mm EF lens that I originally purchased for an EOS Rebel SLR (film camera) about 25 years ago. I used it to shoot my daughter’s soccer game, and it performed like a champ. So if you have a Canon mirrorless camera, here’s my advice for rounding out your lens collection — buy this adapter and then buy a bunch of older EF lenses. You’ll be able to build quite a collection of gear for less than the price of one EF-M lens. HOWEVER, if you’re planning to do video, the EF-M lenses with the STM motor are very nice. They’re very lightweight, smooth as butter and nearly silent. The only drawback is that they’re a little “plasticy” and don’t feel as solidly built as this lens adapter.

Huge cost saver
After upgrading to the R6MarkII I was not looking forward to replacing/upgrading all my EF glass, but this little gem has so far performed flawlessly! AF works as expected, but I’ll check back in if any issues arise. Otherwise, I see no reason to spend all that money on Canon’s equivalent solve. Highly recommend.

DOES NOT FIT MY T5 CANON CAMERA I WILL KEEP THIS. NEED HELP IN ORDERING CORRECT ONE HELP!
PLEASE HELP! I ordered Commlite CM-EF-EOS R Lens Adapter, Electronic Auto-Focus EF to R Mount Adapter for Canon EF/EF-S Lens to EOS R, EOS RP, EOS R6 to use with a 400mm SIGMA lens. It does not fit on my canon T5. Can anyone PLEASE tell me exactly word for word which adapter I should order for my 400mm SIGMA lens to fit my canon T5, XTI? I have trouble understanding which one to order. I will keep this lens as it will probably fit something I have in the future. It arrived super fast and nicely packaged and appears to be of good quality. ANY HELP IS GREATLY APPRECIATED! THANKS!

cheap junk
Do not buy this cheap adapter. The fastener part broke after just a few uses, and the screw was almost instantly stripped. I’m out $50 for a useless, cheaply-made part. Look for another brand; this one is junk.

Useful adapter for M-Series Canon Cameras to EF and EF-S series Canon Lenses
For less than half the price of the Canon adapter, this adapter does a great job of adapting my EF-S 55-250mm telephoto lens to my Canon M50. Autofocus and Lens Image Stabilization perform as expected.The tripod foot that connects to the adapter is not very secure or stable. I used it on my tripod because, let’s face it, the lens is heavier than the camera. The tripod foot wobbles badly, even when secured as tightly as possible. The clearance and tolerance for the tripod foot are pretty key if you’re going to be depending on this adapter as the only thing keeping your camera from falling off your tripod. This small piece likely needs to be better designed for smaller tolerances and snugger fit. Because all else seems flawless, I’m on the fence as to whether to remove a star because of the poor tripod foot snugness.Update October 16, 2018: I’ve positioned a tiny piece of fabric as a wedge to one area of the tripod foot on this lens in order to cinch the wobblies. That seems to have done the trick for now.Commlite — where do we stand on making a product like this into an adapter with speed boost?

Ich war erst skeptisch, da das Produkt im Vergleich zum Canon Originalteil deutlich billiger ist.Es gibt keinen Grund zur Skepsis. Alles sitzt so fest wie es soll. Die Kommunikation von Kamera und Objektiv ist fehlerfrei (sowohl mit diversen Canons als auch Sigmas). Die Fotos sind scharf.Ob man die Objektivschelle braucht, muss jeder selbst entscheiden. Alles in allem klare Kaufempfehlung. Würde ich wieder kaufen, sehe aber keinen Grund, warum das in den nächsten Jahren notwendig sein sollte.
