    • Top quality, must have item for me
For some reason I cannot find any third party full frame RF lenses with AF, only for APS-C. This is the version for the latest R series cameras that not only provides access to the plethora of powerful OEM and third party full frame EF lenses, but also has a control ring like native R lenses for extra functionality like shortcut to changing aperture. I saw some expert YT reviews that said they tried this adapter out and successfully gives their EF lenses a second, and partly even better life. Note that there are numerous third party adapters of this kind on the market for literally a third of the price, but given the importance of this adapter working properly I rather spend the extra money to get max quality - plus, the less expensive versions may or may not have the control ring. I can't wait to try out and buy top EF lenses that would otherwise be out of reach looking at Canon's high RF full frame lens prices they try everyone to buy. ... show more

    • Must have for canon rf cameras
Nice adapter. Now I can save money on lenses without sacrificing too much if any quality. It's not that noticeable but looks good. It fits on camera perfect. The control ring is placed a little odd but still useful. I like to assign ISO to it. Saves time and money what more could you ask for?

    • A must have to keep using your old glass
I’ve been using the Canon EOS to RF lens converter (EF-EOS R Mount Adapter) for a several months now, and it’s been an absolute blessing. As someone with a collection of high-quality EF glass, I wasn’t ready to part with my lenses when upgrading to a mirrorless camera (and I mean buying all new mirrorless lenses to replace them would be pretty pricy). This adapter made it so I didn’t have to!! The adapter works seamlessly. There’s no noticeable loss in image quality, autofocus remains fast and accurate, and all lens functions seem to carry right over . Using the old lenses on an mirrorless is actually a bit of an unexpected treat with the advanced functions of the newer camera. The only con I have is that it adds a bit of length to the build but otherwise totally worth the reasonable price. ... show more

    • A worthwhile investment
A solid option for putting EF glass into your RF lineup. It works seamlessly with my EF 100mm f/2.8L.

    • Get this and keep your cheap EF lenses
Review Image by Godslove
This is a well built, well fitting, well made adapter so you can use cheaper lenses. It weighs nothings and works with RF mount. Compatible with EF and EFs lenses. Was tempted to buy third party ones but thankfully I stuck to the canon. Would recommend

    • Game changer!
Review Image by June
Thanks to this adapter, I can use my EF 24mm f/1.4 lens on my Canon R50. The control ring is a game changer. I’m still learning how to take photos—the second photo was taken indoors at night with very low light.

    • Extends the life of my EF lenses
Good adapter. Extends the life of my EF lenses that I use on my older Canons. I don't use the ring very much so when I get another one, I will get the one without the ring.
