The arrival of the EOS R and the accompanying new RF mount have left some observers wondering what's going to happen to Canon's other mirrorless system – EOS M – and whether Canon will continue support for its EF-M lens mount.
The good news for users of EOS M cameras is that, according to CanonRumors.com, it looks like Canon has applied to patent five new optical formulas for EF-M lenses. The less-welcome news for enthusiasts is that they're all variable-aperture zooms, with no sign of a fast prime.
So what lenses can we expect to see? According to reports they will be:
- 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
Canon already has a EF-M 15-45mm f/3.5-6.3, so it would appear that we can expect a new bundled kit lens to come with future EOS M cameras. Canon also has a EF-M 18-150mm f/3.5-6.3 in its range, so the rumored EF-M 18-130mm f/3.4-5.6 sees another slight overlap.
These lenses are unlikely to excite many photographers, being very much at the entry-level end of the range, and the EF-M lens lineup is still missing some fast telephoto zooms and prime lenses. With the arrival of the RF full-frame mirrorless system, we're not sure we'll ever see those either.
