your Canon d7 would have a crop factor of about 1.5 so that your 600 mm have more reach than what 600 would give on a full frame camera. m4/3 (micro-four-thirds) which are panasonic and Olympus cameras have a 2x crop factor. These have a larger sensor then the sony bridge camera but smaller than your canon. When purchasing a camera body you could easily get a kit lens included, which in the pana for example could be a 12-60 mm (reach like a 24-120 on a full frame). There is a Pana-Leica version of the same lens with more impressive optics, and many other contenders depending on where you want to go. But carrying a phone for the other stuff would be fine for most people unless you want the very best quality in landscape, macro or portraits.
