Hi guys, Arrrghhh...GAS is hitting hard right now. I could get the HLD-6 grip for around $200...so I think I'm going to get it. I do have a few quick questions, though (one right now, more later as I think of them)...how flawlessly does it switch from one battery to another? For example...let's say I'm doing a SUPER long exposure (for argument's sake)...will it switch from one battery to another without interrupting the image? Or if I'm shooting video...will it switch batteries on the fly?
