I currently shoot B-cam with a 60d, but I wouldn't mind trying a mirrorless camera to see if I can figure out a way to help my focus ability. Not necesarilly constant autofocusing (like for moving subjects), but more for like grabbing focus on a subject while stationary. Is it essentially the same sensor as what's in the 60D, and will it work without specialty lenses?

Yes I am using it as a wide safety shot only. It matches my 60 and 6 and it works.....But I wouldn't recommend using it in low light because it is really dirty.

Max, have you read Ken's review of the camera below? Mostly applies to stills, but because I also shoot stills as part of my work I suspect that the camera wouldn't be for me.

I haven't read anything related to stills. But if it adds noise over the 60D, then forget it.
