Canon announced the October 2012 release of it's first mirrorless, DLSR style camera, the Canon EOS M. People seem to fall into a couple of camps on this camera. Either (1) This makes a great, small, portable backup camera, or (2) Why can't Canon push the envelope?
Personally, as a Canon 7D and C300 owner/user, I haven't decided on this camera. For most of the shooting I do the camera seems to solve a problem that doesn't exist. Since the EOS M has similar internals to a T4i I'm not sure why I'd want it. If I need a DSLR camera I'll grab my 7D. If I want to shoot long interviews I'll grab the C300. If I need something quick and dirty I'll grab either my cell phone or my Canon Powershot (yes, I'm in bed heavily with Canon...).
My one wish was that Canon would build the camera with EF mount. That would make it an ideal backup camera to any 5DII, 5DIII, 7D, or 60D owner. Instead it has its own mounting system, EF-M, that will handle corresponding lenses (currently only 2). The EOS M can, however, handle EF mount lenses with a forthcoming adapter.
