Heritage Cameras

Tokina, I think you'll find.

Excellent – glad it worked out for you.

I've just noticed that the OP was asking about an "official" EF-M to R adapter. What's the chance of that appearing? Close to absolute zero, in my opinion. If Canon wanted to make such an adapter, ...

Pentax got back into autofocus with the SFX (SF1) camera and SMC-Pentax F lenses in 1987, and all the company's AF film and digital SLR cameras since have had the screw-drive AF coupling in the ...

Feasible? Yes. Likely? No. There are two ways such an adapter might work. Firstly, as EF-M lenses are narrower than RF ones, an adapter might just be possible that recesses them 2mm into the R ...

A menu option for AF > 1> Eye Detection AF > Enable at 05:59 on the video looks pretty much like conclusive evidence to me...

You're right, of course – just under 8mm (1/3-inch) for Leica M to EOS R. With a helicoid adapter you could even focus it!

Don't forget to add on around 25mm (one inch) for a PK to EOS R adapter... ;-) Unfortunately CameraSize doesn't seem to have that one. :-O

...and here's a really, really small full frame pancake lens to go with it (Leica M helicoid and loadsamoney required): https://www.kickstarter.com/projects/1745517054/35mm-f-27-the-smallest-fastes ...

A tele converter could also allow APS-C lenses to cover full frame... ;-)

...and here's what the EOS R might look line with a future pancake lens: https://camerasize.com/compact/#716.345,799.345.5,799.345,ha,t

You're very welcome. Take Tom's good advice above on how best to use it, and good luck!

The most successful way I've found is using a special tool like this: DSLRKIT Pro Lens Vise Tool Repair Filter Ring Ajustment Steel 27mm to 130mm That isn't the one I have, but there are many ...

Canon certainly does like to recycle model names: https://en.wikipedia.org/wiki/Canon_R_lens_mount Others that have been re-used include EF (first a manual focus SLR, then an AF lens system), EF-M ...

I think you'll find those are EF lenses not RF ones, and are just being announced at the same time as the R system. The same applies to the EF-M 32/1.4.

True, but there are several adapters available to use them on mirrorless cameras.

Pretty sure that's Fujica bayonet fitting, for the AX/STX series of 35mm film SLR cameras.

Tom, the screw-drive AF system has been dispensed with in the FTZ adapter... it only auto focuses with lenses that have their own AF motors: AF-S, AF-P and AF-I types.

Some of the budget film kit lenses were also G but not AF-S, such as the 28-80mm f/3.5-5.6G and 28-100mm f/3.5-5.6G . Probably not the most likely lenses to be adapted to a Z6 or Z7, though...
