I have the 1D mark IV on a tripod and pointed to a bottle which is on the table.
Camera settings are : AV, AI SERVO an 10FPS burst and 5FPS (slow setting)
With 10 FPS I noticed that not all frames taken are exposed correctly.
With 5 FPS It seems all frames are correctly exposed.
I was wondering if it is normal that some frames are not exposed correcty with AI servo / 10 FPS combination ??
