I just noticed that the plate that surrounds the tripod socket on my BG-E4 is buldged out a little bit--but the one on my BG-E2 isn't. Can someone else with a BG-E4 confirm whether there's is flat along the bottom, or bulges out a little. It sort of looks like its supposed to be like that, I just want to make sure its not broken (or breaking).
I've attached a picture, but its kind of difficult to see. 
Thanks!
