Canon DSLR home-video. Need advice
As far as I know the Canon 650D is the only Canon DLSR that has full auto focus during video recording. Not sure about the face recognition though.

Do some research on it. If you really like the DSLR look then I think this is the camera for you... especially as you'll be able to use your 85mm and 35mm lenses. 

I don't know too much about other camcorders but I doubt you'll be able to find any that can give you that DSLR depth of field for the price of the 650D.
