1. Flickering in 50D footage is caused by turning off exposure simulation in camera
2. Same 50mm f/1.4 Nikkor on both camera's. Changed distance to object with 50D to compensate for cropfactor.
3. The 5D Mark II was set at iso 6400 for f/16 and 100 for f/2.8, 50D should have used about the same values, but it was calculating them.
4. The first shots (5D and 5DII) both are brightened + 1 stop in ACR. No oder edits, only tried to match white balance.
