Mark - I feel pretty certain it will. My BG-E2 for the 40D does and the photo shows the same recess on the Vertical Stalk. I don't use my BG-E2 often as I shoot mostly from a tripod and don't like it for that purpose. It is very convenient for shooting handheld portrait oriented scenes. Part of my original decision to buy it was to be able to use conventional batteries in a pinch. However I have 2 stock batteries and that's been good enough that I don't use the grip for that either.
