I have 2 different questions about the 5D mark II First off I notice in live view the brightness of the picture goes up and down automatically. I looked in all the settings and don't see any setting to turn this off. I see one for LCD brightness but that doesn't fix it. It appears to only happen if I am in AV (aperture priority) mode. I also have exposure simulation off. If I switch to manual mode it doesn't do this. Anyway to fix this? Also I don't see any picture-movie mode switch. Since I have only done pictures with the camera it hasn't been something I really looked at. I know that I can record movies by hitting the set button but shouldn't there be a movie mode selection? The reason why I ask is that I have my camera hooked up to a remove shutter and would like to remotely control the record on and off with the radio as well.
