I saw the PetaPixel post and studied the picture. I immediately grasped what it was all about. Then, it took me a good 10-minutes, during a leisurely walk in the dark with the dogs, to work out what it was all about.
It is NOT a lens adapter. We already have plenty of them — such as the ‘EF-EOS R Mount Adapter (with Control Ring)‘ shown above.
This is a hulking BIG convertor replete with retractable mirror, a pentaprism equivalent, an OPTICAL VIEWFINDER and maybe even a focusing unit.
When you attach it to a Canon mirrorless camera, e.g., my Canon EOS RP, via the lens mount you will have a camera with TWO (2) viewfinders — one on top of the other! One electronic (in the body of the mirrorless) and the other OPTICAL above it.
For those that insist that they have to have an optical viewfinder and to speed-up autofocusing.
But, why? Why not just get a DSLR? And that is what this seems all about.
IF Canon is serious and actually releases this, it would mean that they will no longer make high-end DSLRs! About bloody time too.
They will just make mirrorless bodies — and I am totally cool with that. I have and will continue to be committed to mirrorless.
So, in future, all the lens sensors and technology (bar faster autofocus) will be in mirrorless bodies.
Then, those that demand an optical viewfinder will have to get this convertor.
Not sure it will work in practice. The technology will work. It is pretty trivial. Even I could design one of these. Not sure anybody will pay nay good money to buy one. They will switch to Nikon.

Though it was pre-announced, Canon in the last few days announced the availability and the pricing for the RF 24-240mm zoom. I hadn’t looked at it much previously because it was not available.
As soon as I looked at it I noticed the absence of the RED Control Ring. Looked harder. It only has two-rings: one for zooming the other for manual focus. IT is a bona fide RF lens, so where is the Control Ring?
I went looking. Here is the answer. It does NOT have a DEDICATED Control Ring!
When you are using auto focus (AF) the focus ring can be used as the Control Ring, BUT that does not work in manual focus mode.
That is very poor and disappointing. Shame on YOU Canon. Talk about breaking a promise so early.
Well, does NOT matter. I will not buy this lens. I wasn’t going to buy Japanese anyway until they stop commercial whaling.
My new Tamron 28-300mm, with vibration control (VC), has better reach, decent image quality and a CONTROL RING because I use it with an adapter that has such a ring. So, Canon you know what you can do with your new 24-240.
I like my Canon EOS RP. No buyer’s remorse. It is an easy camera to use and I just LOVE the Canon lenses. I had missed those.
I definitely would have no qualms about recommending the Canon EOS RP to anyone. It is affordable and well-worth the money and THE LENSES. Yes, the lenses. Get the camera for the new lenses.
Yes, I had plans for that Control Ring well ahead of purchasing my Canon EOS RP 3 weeks ago.
I like as many control wheels as I can on a camera — which is why, for about 6-months, I was totally convinced that the Fuji X-T2 was going to be my dream camera. Now, with this control ring on the lens (or on the lens adapter) I do have a 3-wheel camera.
As I show in the top diagram I assigned ISO control to that ring. Exposure compensation (EV), automatically, is on the rear wheel and since I shoot in ‘Aperture Priority’ mode most of the time, aperture setting is on the front wheel. Works great for I — though I am still getting used to finding the right — of the three rings — on my 24-105mm lens.
But, this is definitely worth keeping in mind. Really makes the Canon EOS RP a joy to use.
