It's just a different way of describing an adapter, so it's obviously possible. What I'm hoping is that Canon has a way to route the RF protocols through the pins on an EF mount, so the EF lenses which were released in the EOS R era can behave like an actual RF lens when adapted - maybe using a special control ring adapter sold for this purpose. This would apply to the 400/2.8L IS II, 600/4L IS III (which I have, so personal interest here), and possibly the 70-200/2.8L IS III and 70-200/4L IS II. As it happens they are all white lenses, so a white adapter would be appropriate - and no doubt hugely expensive...Removing a rear segment from an RF mount to reveal an EF mount, is not even possible.
The current adapters are designed for full compatibility of EF on an R mount so in what way would a new adapter differ?It's just a different way of describing an adapter, so it's obviously possible.

Regarding the “cool” adapters coming, this has got to be 1.4x and 2x flip-switch TCs for EF big whites. Then all eventual RF big whites would have a removable rear segment to reveal an EF mount so they could be used on a DSLR (at the slower EF mount communication protocol) or accept the flip TCs that engage the extra RF connections.
RF Big Whites:
All intact — RF mount
Rear segment removed — becomes EF mount
Rear segment removed — accepts flip-TCs
This way there would additional functionally added to EF big whites, making those that use them want to switch to R bodies. And Canon could wait to make RF big whites until the next planned upgrade cycle for each lens since the urgency to deliver big white RFs would be removed.
Simply put, they can sell RF lenses with adapters that remove for EF.You mean like when you remove the current EF EOS R Mount Adapter off an EF big white?
You’re missing the logic: All Canon RF big whites could continue to be EF lenses with an RF adapter on them, only the adapter would be matching white and perhaps more rugged or have some sort of additional locking mechanism for added strength. Simply remove the adapter and replace it with a flip-TC also in white. Simply remove the adapter and use it on a DSLR. Leave the adapter on and it works on R bodies just like the EF lenses do now.
I’m basically saying they make a more pro white EF-RF adapter than what they already make — and bundle it with every big white lens, already attached. It makes the lens seem more like a modular RF lens than calling it an EF lens with an included RF adapter.
200f2 with switchable TC would be very usefulYeah, for sure there would be some big whites to prioritize for improvements. It’s just a flip-TC RF adapter for EF big whites would help reduce the urgency of calls to see RF big whites released while adding a huge feature that would draw DSLR big white owners over to the R system.
I do hope the first RF big white is either the 300 2.8 or the 200 f2.
They already have that. In fact they have three versions. Why would they include an RF to EF adapter with every lens when no one needs more than one adapter? It doesn't make the slightest bit of sense.Simply put, they can sell RF lenses with adapters that remove for EF.
Using the current adapters, an EF lens on an RF-mount body should behave just as it does on an EF-mount body, which is already a great benefit of course. Being able to fit any of my EF and EF-S lenses to an R5 without any worries over compatibility is one of the things which makes the switch to mirrorless viable. In addition, optical performance will be just as good as before. But the RF mount also offers benefits from the increased communication speed, which improves image stabilisation and (I believe) EVF performance. It would be good to have that if possible.The current adapters are designed for full compatibility of EF on an R mount so in what way would a new adapter differ?
the rf 70-200 2.8 is described as not compatible with extenders on the canon website. Im wondering why they say that every lens will work. this would be great.

Maybe your assumptions that a product few of us have actually seen yet will have protrusions that preclude it's use on the majority of lenses its designed for is false?I am not seeing how that would be possible given the protrusions on the teleconverters and the position of the rear element on many current RF lenses.
They already have that. In fact they have three versions. Why would they include an RF to EF adapter with every lens when no one needs more than one adapter? It doesn't make the slightest bit of sense.
This is also what i thought but the pictures, canon is showing as the RF extenders, are looking like they wont fit any rf glass. Maybe the pictures are showing extenders which work as EF Adapters at the same time. We will see.I guess as right now there is no (RF-)TC, it says no compatibility. To which TC should it be compatible at this point? So i guess when the TCs are announced they will change that.
i mean: why release TCs of there would be no compatible lenses?
For EF lenses, the Viltrox and Metabones work fine. For RF lenses, not happening. You need the extra flange distance to make a speed booster work.high quality speed booster for the m system please
