7D owners, help me track a flicker problem

[Helen Foster]

I’ve got a Canon 7D and have been trying to address flickering by eliminating one possible source at a time. I’ve shot in manual, turned off auto white balance, covered the viewfinder, disengaged the lens contact points etc and am STILL getting flicker.ive been shooting in RAW only. I’m concerned I’m going to wear out my camera trying! However I think I’m missing something, and that there are some in – camera setting on auto that I’m overlooking.
