I've never been one for using Live View, but I've been playing with it lately. It really uses up the battery, so I am shopping for a battery grip. I don't have the funds to buy the Canon brand, but I've seen very positive reviews for the Vivitar one that fits the 50D. One person did complain that it doesn't have the AF - ON button though. This led to my "clueless" question; I thought all the grip did was hold two batteries, replacing the single battery in the camera body - and all camera functions would be handled the same way as if there was no grip (I shoot hand-held or on a tripod with a cable release). I see that there are wireless grips reasonably priced too, and so I wondered if using a grip means it overrides the camera body's controls? Are there control buttons/dials on a grip? Go ahead a laugh at my dumb question, I don't mind!
