Canon Mount Adapter EF - EOS R, Compatible with EOS RP, EOS R, EOS R6, EOS R5

I knew I would have to purchase a EF adaptor when I purchased my EOS R so that my existing Canon lenses would be fully utilized. have been using the standard adaptor (the control ring adaptor was out of stock) and it has been working I have no problems using the autofocus and all functions on my EOS R just as well as I do The autofocus function on this adapter is even faster and more accurate than on a DSLR, so I am able to use lenses even more effectively than before. Unlike a conventional glass spacer, this isn't slowing down the image quality and since it is a spacer with electrical contacts, there is no glass to degrade it. You should get the control ring adaptor over the basic one if you're going to get one, as RF lenses come with a control ring built in, so if you're going to use adapted EF or RF lenses you can have a consistent experience. There is only one difference between RF lenses and adaptors-the control ring of the RF lenses is closer to the front element and that of the adaptor is With the adjustment ring being closer to the body on the adaptor, it may be easy to turn it without noticing, so keep an eye on what you are setting. When I first started using it, I had issues with changes to my aperture setting accidentally happening. However, today I do not have issues with this anymore because I've adjusted my behavior.

My EOS RP came with this lens adapter, so I could use EF lenses like the 135mm f/2L with it. All works as advertised and the build quality is excellent, but I would like to see some extra attention paid to the interior. (1) The control ring somehow remembers the value it was set to when you switched between this and a native RF lens, so if you switched between these, you'd notice jarring and unexpected changes to The thing is that you may think it's a feature, but it is for me It was very disorienting to switch lenses and then have the camera jump to a completely different ISO value (left over from a previous project) when I was using the control ring (on the adapter and on RF lenses). DON'T MISS THIS! Normally I would expect the current value for the control ring setting to be associated with the camera, but it appears to be associated with (2) The design of this adapter was a big ergonomic mistake by Canon. As soon as they had created the new RF lenses, they said, "Hey, let's throw in a new control ring!". I think we should put this in front of the focus and zoom rings, so no one will be confused. Thereafter, a junior engineer was charged with designing an adapter to use with older Using the adapter itself, he was forced to install the control ring - a very awkward process for him. The camera lens is a bit dirty at the back. In any case, here we have an amazing adapter that will make your life easier There is a new RF lens control ring that is in the COMPLETELY opposite location from the bang control ring. I'm so sad! As a result, the control ring should have been placed on the backside of the RF lenses rather than on the front side. So the consistency would be there as well. Ain't it nice if it had worked that way?.

After borrowing an RF lens and having a look at the control ring functions for ten minutes on a native lens with the standard EF/RF adapter (without a control ring), I had absolutely no problem spending the $200 or whatever for this. Once you have done this, your roleplay will go from being likeable to being loved. The rotation on this is switched to controlling exposure compensation during aperture priority, which makes bracketing shots so much easier. . . In manual mode I can turn it to control aperture with the rotation switched to being reversed (since I easily turn the wheel right and the meter/histogram moves to the right). It matches the body seamlessly and has a nice finish. There is a good fit and a solid fit. There's nothing like RF glass on a camera. It feels like it's part of the camera, just as it will be until I get my RF glass.

The EF-S I bought is a good one In order to use my existing EF lenses with my new EOS R body, I ordered the EF Control Mount Ring. Due to the lack of glass in the mount, there seems to be no drop in resolution. With the Control Ring, you can change ISO, or another function you might need to change often, right on the mount, as opposed to the cheaper one. Since I have been an amateur photographer for many years, I probably would not have cared about the cheaper model. Although I'm sure that as I use the Control Ring more frequently I'll become accustomed to using it and wonder how I got by Being able to add that extra feature is nice.

My EF L lens collection is all I need (for the next five years at least) so I didn't need to upgrade. I did need to upgrade my camera body, and the Canon EOS R was the perfect choice. My EF lenses work very well with this control ring adapter (I used it to control ISO and exposure compensation with auto exposure) that provides a new feature that fits in extremely well with my It's much more comfortable to stand near the camera than I'd like to be in front of the camera On the RF lenses, the control ring is located at the center of the lens.

The product is great and does exactly what it says it will do. If you already possess an EF, you can upgrade You might want to think twice before purchasing this adapter if you possess an EOS adapter. You have to determine whether or not the investment in this adapter is worth it for your shooting habits. Don't get me wrong, I love the new control ring, but you have to decide it is worth it for you. In my experience as a manual shooter, I am constantly adjusting my settings for even the slightest change in lighting. You'll probably be better off passing on this if you tend to use Auto, Program, or AV/TV a lot.
