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, EOS R5 Series Mirrorless Cameras

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.

This works well to adapt my EF 24-70 to my mirrorless body for portraits

As soon as it arrived I attached it to my M6 and tried it out with my EF 40mm f 2.8 and EF 70-200 f 2.8L lenses. No problems at all with the autofocus on either of them. Created a short video with the 40mm and the autofocus worked quite nicely when shifting between two subjects near and far. Neither lens has IS so I can’t comment on that aspect. All photos and the video appeared to be sharp. I think I saw a review that said the images were soft around the edges, but that was not my experience. The design appears to be quite robust and of good quality. The tripod mount on the adapter is removable (I wasn’t sure if it was at the time of purchase) I would recommend this adapter very highly, especially given the cost difference between this adapter and the Canon adapter.

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.

Works well

Encajo perfecto en el lente

This adapter works great for my Canon R10 to be able to use my DSLR lens. It’s snug and holds the lenses well. I was a little worried using a third party aftermarket product but it works so well and is much cheaper than the one Canon offers. I highly recommend it.

So far so good, been using it with my Canon EOS R10 with no issues.

Não posso avaliar, não serviu no meu equipamento. Agora tanto o vendedor como Amazon me deram total condições de troca de equipamento.obrigado.

正直純正品ではないので、本当に大丈夫かと半信半疑で購入してみましたが、全く問題ありません。ガタとか接触不良なども今のところ皆無で満足してます。

I use this on a canon M100, with several different EF and EF-S lenses, with absolutely no issues whatsoever. The fit is tight and secure, and all camera and lens functions translate through the adapter flawlessly. Good solid metal construction, and the tripod mount attachment is sturdy as well. I have used it with a Canon 70-200mm F4 L telephoto lens, and it was rock solid. Some people have said the the tripod mount was loose, but this is not my experience, as long as you tighten the attachment screw very tight. Money well spent, and money saved, with this adapter.

Acheté pour mon Canon R5 pour monter mon parc objectif EF-S. Fait très bien le travail. Satisfait.

The product is equivalent to the canon original adapter. Auto focus works well. I used it with the 55-250mm lens. It works like a charm. Good value for money
