Am I right in thinking that the Vertical Grip is the same as the one used in a550?
100 % correct
. While the battery life is excellent (unlike say a 550D/Rebel T2i), it's nice to have the option. Makes for a much better balance between the camera and a heavy lens like a 24-70 or 70-400.
! I'm still holding off until the A700 successor will be here (should be somewhere next year)...
