Canon continues to work away at EF-M lenses judging by this recent patent application. It looks like they’re working on improved optics for kit zoom lenses, sharper performance and less vignetting are on order.
EF-M Zoom Optical Formulas in Japan Patent Application 2019008235:
EF-M 16-50mm f/3.5-5.6
EF-M 15-45mm f/3.5-6.3
EF-M 18-130mm f/3.4-5.6
EF-M 18-200mm f/3.5-6.3
EF-M 15-130mm f/3.5-6.3
We expect a new EOS M body in the coming months and it wouldn’t surprise us to see a new kit zoom announced alongside the camera.
