Canon Patent Application: APS-C mirorless zoom

Perhaps a hint at RF APS-C?

Canon recently had a patent application for a mirrorless zoom.  While this is pretty normal, perhaps the timing is not.

The EOS-M system already has a mirrorless zoom lens for this focal, so either it's an upgrade, or Canon is looking at doing new APS-C lenses for mirrorless for perhaps the RF mount.

What's also curious that if Canon was doing the 18-45mm as an APS-C lens (we do know a 18-45 is coming), then this would nicely fit in with that lens.  However, to be fair, the EOS-M system also has a 15-45mm, so it's not a slam dunk.
