Canon will announce an EF-S 35mm f/2.8 M IS STM on April 5, 2017. What we find unique about this announcement is the “M” in the lens description. We’re not sure what that means…

Here are a couple of ideas off the top of my head:

Macro mode?

EOS M compatible?

Leica made it?

Here are the best reader ideas:

From GHPhotography “Perhaps M is a designator for macro mode with the integrated LED lights from the EF-M 28mm f/3.5 IS“

What do you think?

Availability and pricing are not known at this time, but we don’t have long to wait.
