Japan Patent Application 2018173487 shows a bunch of different optical formulas for new EF-M zoom lenses.

Lenses included in the patent:

  • EF-M 15-130mm f/3.5-6.3 IS STM
  • EF-M 18-130mm f/3.5-5.6 IS STM
  • EF-M 18-200mm f/3.5-6.3 IS STM

According to Canon News, the major focus of this patent application is making lighter focus groups, which would improve AF performance and prevent “wobble”, which would be important for video work.

The EF-M 32 is the only lens for my EOS M50 I bought with strong confidence that this is a lens I like - the 18-55 was with the original (EDIT: EF-M(bullshit)) EOS M and I bought the EF-M 22 because I wanted a brighter lens but 18-55 is IQ wise o.k. but not stellar and the 22 is IQ wise good but the wrong focal length for me as a one-lens-solution. There is a good chance that 18-55 and 22 will go away soon but the 32 will stay.

An EF-M 15-60 f/4 IS would be the 2nd lens I would buy with full intention to use and keep it (if IQ is at least good ... excellent). So it is a pity for me that we maybe see a lot of f/x.y - z.a zooms for EF-M but no fixed max aperture versions!

Was disappointed with the current EF-M 18-150 lens as it's prone to flare. Hoping the new versions have better performance in this aspect.

lol. Some flares when sun is in frame are no problem for 99,9% of buyers of this lens I'd guess. :)

EF-M 18-55 has gone away alrready (unfortunately "replaced" by sub-par 15-45).
EF-M 22/2.0 will (hopefully) stay for many more years. Don't see any reason why Canon should/would discontinue it.
If anything, they will hopefully extend the prime lineup to longer FLs, like a 50/1.8 IS STM and even more importantly a short tele prime around 75 to 85mm f/ 2.0 to 2.4 IS STM - whatever is possible withing EF-M size conventions.

I was not precise: 18-55 and 22 will go away FROM MY BAG ... yes the 18-55 is gone from market while beeing very o.k. and shurely the 22 2.0 will stay because it is THE compact-APS-C-moderate-wide-angle-package component in Canon land and maybe unique - especially with the old EOS M.

15-60 4.0: So two would buy it - divide the engineering cost by two ... o.k. the equivalent of a very very complete FF set with 20 lenses including TS and big whites :)

The 18-200mm sounds real sweet.
This would be my one lens.
If wider were needed my current EF-S 10-18mm covers that in a light compact package.
