Will Canon's FF Mirrorless be EF or EF-M Mount?

One lens I keep using as an example to have great benefits on e-mount is my favorite 17L/4.0 TS-E. No exaggeration if anyone actually try Canon TS-E lenses on e-mount, you'd agree it's just so much easier and lots more effective than on Canon EF-mount itself.

I shoot TS-E lenses (used to own 24L TS-E II also) as a P&S lens most times hand-held. My eye stays in EVF all the time even under bright sunlight. With Canon DSLRs, you'd have to use back LCD for precise MF that is unpractical in bright sunlight.

Then right in EVF, either with magnification toggle (1x/5x/10x with A7r II or 1x/7x/14x with A7r) or with focus peaking (very accurate so I use mostly these days), I can get precise MF in seconds. Well, on Canon DSLRs, you'd have to push button a few times to get into magnification.

If you use Tilt function, it's just so easy and effective with focus-peaking to get the best balance in end to end sharpness in seconds to achieve indefinite DOF (that something regular lenses just cannot even stop down to F22 which only deteriorates IQ). Well, on Canon DSLRs, it's a trial-and-error tedious practice. You'd better to use a third-party monitor plug-in hotshoe to get similar sort of focus peaking. Basically you'd have to shoot on tripod with Canon DSLRs (unpractical under bright sunlight) while I shoot mostly hand-held on A7-series.

Here is a sample that I am challenging Canon and Nikon DSLR owners with respective 17L TS-E or 19G PC-E lenses. I can easily to get pixel-level sharp photos at 1/6 sec (A7r III IBIS is even better) and can push to 1/4 sec. Try on 5DsR and D850 and let's compare hand-held as tripod is absolutely not allowed inside unless you have special privilege.

Very good points and the reason that ultimately all professional use will migrate to mirrorless systems.

it would be the reason if all pro only take photos of building that don't move

Mirrorless also can handle moving subjects such as on a moving eye or fast moving subjects in sports and wildlife as the latest models from mirrorless camp. This is only beginning, the beginning of the end of DSLR era in 10 years probably. Really nothing a DSLR can do, a mirrorless cannot do these days but only do more in some areas.

a was not referring to AF but IBIS wich was the main point being made with the above shot

BTW, there is nothing a mirrorless can do that a dSLR can do in principle, either. That mirror can be lifted, you know.
