This could be as much of an educated guess as a rumor. Nevertheless, recent rumors point to a new Canon EOS-M model that sports an electronic viewfinder to be unveiled in late 2013.
One of the most lamented non-features of the Canon EOS-M has been the absence of a viewfinder. Enthusiasts were lambasting Canon before the EOS-M ever hit store shelves over the lack of an EVF. While Canon never confirms what’s coming down the line for its camera systems, executives have emphasized that the EOS-M was its first foray into the mirrorless market and that there will me more cameras built for different users.
Additional rumors point to the styling of the camera as similar to the current EOS-M model and that it won’t be taking a retro design like some of the other mirrorless models out there (e.g., Olympus, Fuji, etc.).
