My BG-E16 came in for my 7D2. The first thing I noticed was the tray you need to use in order to install batteries in the grip. There are two trays, one for AA cells and another for a pair of LP-E6N. The tray loads into the end of the grip. The tray makes the grip needlessly thick. As a result, the distance between the shutter release button and the AF ... buttons on the back are a good half inch further apart then they are on the body. My hands are not small (I'm 6'2") and the difference is not entirely comfortable. The little lever below the joystick replicates the function of the lever around the joystick on the back. The issue with that is it is nearly impossible to flip the lever and rotate the wheel just behind the shutter release on the grip with one hand (I use that combo to change the ISO).
They should have maintained the geometry of the controls found on the body and they should have done so with a trayless design. Not sure what they were thinking.
