Canon is still working on a full frame mirrorless camera
The latest report from CanonRumors indicates that Canon is still working on a full frame mirrorless camera:
"We’re told once again that a full frame mirrorless camera is definitely in the works at Canon. As we’ve also said before, the biggest challenge to the design team is making good use of EF mount lenses. There will not be a 4th mount (EF, EF-S, EF-M) added to the Canon ILC lineup. It’s possible we’re going to see a full frame mirrorless fixed lens camera from Canon before we see an ILC full frame mirrorless. We were told a while ago that such a camera was in development and apparently that is still ongoing."
