As I sit here impatiently waiting for my 7D to be returned from Canon (Expected Arrival Monday), I have been going through the user manual and the Canon videos trying to familiarize myself with the camera. I couldn't help but wonder what your favorite features on this new camera body. With what little I know about this camera, two things seem to really impress me.The custom control/button settings and the various AF settings, especially the Zone AF. So, what are your favorite features of this new camera?
