No... this is for the EF-S bayonet.
Unless you have the adapter for EF/EF-S to EOS-M.

NO. EF/EF-S mount is not EF-M mount. There is, however, the inexpensive EF/EF-S to EF-M adapter, with which it works. Even without light loss and equally fast autofocus.

Hello RomanL1. I am a little surprised by the answer. According to the Sigma manufacturer's page, the camera mount must be a "Canon EF mount". Here is the link with the details from Sigma: https://www.sigma-foto.de/objektive... - According to the Canon manufacturer's page, the Canon M5 also has an EF-M lens mount: http://de.canon.ch/cameras...
