The adapter is very nice quality and it does exactly what it’s supposed to do. My EFS lens snapped right in there and power from the adapter. Everything feels like metal and it has a nice texture too.

Fully functional, with no loss of speed or accuracy. I am not a fan of adapters, but it works PERIOD

I wanted to try an old lens on a whim. It works perfectly. I have a 28-105mm 3.5-4.5 USM from 1998. It focuses more quickly and more accurately on my R8 than it ever did on my old A2E. It attaches firmly and smoothly. It will stick out farther than normal RF lenses.

This adapter does what it supposed to do. My EF lenses, large and small, fit perfectly using the adapter and all of the camera functions work flawlessly. Why did I give it 4-stars instead of 5? Here's why: Even though the adapter is not at fault, if Canon would get on board and significantly lower the prices of their RF lenses AND allow 3rd parties to make affordable lenses, then many of us would not need this adapter--for now, the better RF lenses are simply unaffordable for a great many Canon camera users. Peace.

I have a bunch of full frame EF Canon lenses. I have had no issue using this adapter with my Canon RP mirror less camera and Canon EF lenses. The only issue I have had is with an older Sigma 150-500mm as it appears the image stabilization doesn't activate when using this adapter.

I ask experienced users to confirm that this adapter works with my camera Canon EOS R 100P.S.I am happy to confirm that this adapter fits the lens perfectly. We can see how much more light flows through the new lens than through the lens that came with the camera.

This is a decent alternative to the Canon EF to RF brand adapter. However, for months, I could not figure out why my Canon R6 battery would drain after the camera is turned off. For example, I complete a photoshoot with 80% battery left and turn off the camera. 24 hours later, I turn on my camera and the battery is nearly half depleted in the 40% range.Ultimately, troubleshooting determined that this EF to R adapter was the culprit and when there's an EF lens on the adapter, the adapter is drawing power from the camera, even when the camera is turned off.I purchased a legitimate Canon EF to R adapter and this is not an issue. The parasitic battery drain only occurs with this adapter, so I assume I have a faulty adapter here. The adapter is still usable and there's no issue with AF from the lenses, just the issue with the battery drain.There are ways to combat this issue alternatively by either removing the adapter when not using the camera for a photoshoot or removing the battery when not shooting. Removing the battery is the quickest option in my opinion.

8 month review:I wasn't sure if this would be as good as the official Canon one, but it does exactly what it's supposed to with zero issues whatsoever. I've done oodles of lens changes over the last 8 months as I do light painting, hyper-macro photography, and travel photography throughout Central America.Screw Canon's overpriced ones. Buy this.

Awesome adapter, works as advertised, have been using on my second camera body to use a wider range of lenses. This thing gets tons of use in my camera bag and after more than a year of use I can say it’s durable as well.
