I use my 6D a lot and love it but I've run across a weird quirk which I could use some help with. When I use Aperture Priority mode everything works great. When I manually stop my lens down the live view screen will get dark for a quick second and then lighten up to what the exposure would be. Exposure compensation works as it should to brighten, etc. But it doesn't work this way when I switch to manual given the same settings (shutter speed and aperture) even though the metering works. The screen will be dark but the metering will show -1, 0, etc and looks fine when I take a picture. It's like the exposure simulation isn't working in manual for some reason as the screen stays dark. Is there a setting that I'm missing? Thanks for the help!
