Control Ring Mount Adapter EF-EOS R for Canon EF/EF-S Lens to Canon EOS R RP R5 R6 R7 R10 Series Mirrorless Digital Cameras

I bought this to use on a new Canon R50. I have several legacy lenses from my Canon digital EOS cameras going back to 2003.Set up for control ring for aperture was easy.Focus stacking works with all lenses listed and tried so far.Auto focus is better and faster on all lenses than on my last Canon 60D - and that is saying a lot because that camera focused all my EOS mount lenses quite fast and accurately.(NOTE: I have an EOS to Micro 4/3 adapter from YKEASU for my OLYMPUS cameras and several of the below lenses don't function on my Olympus cameras (OMd-M1 mark II and M10 mark II Others, such as the Canon 400mm f5.6 focus well in better contrast scenes, but nowhere near as good as on an EOS body)Lenses I tried on the Canon R50. All functioned better than on my EOS Canons, even in low contrast scenes in very low light at dusk in shadow.Canon 50mm f1.8Canon 18-55 f3.5-5.6 (tried both the normal one and the one with IS)Canon 135 f2Canon 135 f2 with Canon 1.4xCanon 400 f5.6Tamron 90mm SP f2.8 macro ( just hunts on Sony A7RII (with Sigma adpater) and Olympus M1 Mark II, so a huge difference)Tokina 12-24mm f4Sigma 14-24mm f2.8 (works far better and quicker lock than on the Sony A7RII that I bought it for, along with the Sigma MC-11 - At the time I bought the Sigma, it wasn't available in Sony E mount.All EOS mount lenses mount as they should. The mount of the adapter to the R50 is slightly tight, but not overly so. Still, I consider this perfect for someone wanting to use EOS lenses with the R body.One thing that surprised me was that every lens I mounted on the R50 with this adapter can be used properly with the focus stacking feature. Your experience with vary depending upon how stilled you are with using focus stacking. I have been using it for a couple years on the Olympus cameras, and longer with focus bracketing. With Olympus, only certain lenses, all Olympus lenses, can make use of either focus stacking in the camera, or focus bracketing for compilation in a image editing program, such as Affinity Photo.But focus stacking on the Canon R50 works with any lens, so I have made good use of it so far with the Tamron 90mm macro. What is more interesting is that it even works with my 400mm f5.6 to get mid-near subjects (20-50 ft) in focus with distant subjects. A tip is that you really have to set the spacing wide to accomplish this.This adapter is a far better deal than the Canon adapter at twice the price. The control ring makes up for the lack of two dials to control aperture and shutter speed on several of the R series bodies. The Control ring is also quite natural to use for aperture because those of us who have used manual lenses are used to working with an aperture ring on the lens.yes, I recommend this adapter for the EOS lenses to Canon R bodies, at least with use on the R50.

Exactly what I needed. Works without any issues on my camera and with canon and third party lenses. Great value compared to name brand.

Works great with the Canon R.The ring changes the ISO which is really helpful when shooting. 👍Flash photography

Worked great on new R100 to use lenses from Rebel camera.

Everthing worked on canon r body except control ring.

I used my 24 to 105 lens and 70 to 200 lens and this adapter works wonderfully on my R6 Mark 2. I tried one of the cheaper adapters and had trouble with the electronics connecting consistently. Even At half the price I would never purchase anything like that again

Poor image quality. Not worth

Does the job, as it is suppose to do. Now I can use al my EF lenses.
