For a
slight diversion....
I presume the data here are accurate:
https://en.wikipedia.org/wiki/Canon_EF-M_lens_mount
===============================================================
So it is (apparently) true that there is exactly one auto-focus third-party
zoom EF-M lens...the Tamron 18-200...introduced in
2014 (!).
===============================================================
One can imagine a number of reasons for the paucity of zoom AF EF-M lenses...but what should be fun to speculate about on a rumor site is whether or not this fact, for whatever reason, contributed to the demise of EF-M.
I don't know the answer to this 'question', but neither do most (all?!) of those who post here. But for sure corporate Canon has played a role in this sort of thing.
And I do find it interesting that, for years, commenters on this site and others have lamented the paucity of EF-M mount lenses!
Now there are posts here and elsewhere stating, basically, that they want a diversity of choices in their RF lens options...and some of these folks are posting that their whole 'decision' about the RF mount is dependent on this very thing!!!
I have no reason to disbelieve those who express these views...but as far as EF-M lenses are concerned...I always found Canon's options sufficient for the way that I (and my family) use M-mount cameras.
A necessary fact (no snark): in my family, we have acquired about 20K images with EF-M cameras and lenses--the format has played at least some role in our daughters' continued use of their Ms, along with the iPhones, when they travel.
But I'm inclined to lean
slightly (55%-45%?) in the direction of those who think Canon is shooting themselves in the foot if in fact they are clamping down on third-party RF lenses.
And my view has always been that the EF-M format has always sort of been Canon's 'test bed' for mirrorless.
