Hello!!
I have noticed a problem while shooting with my 5d mark iii yesterday, i have some exposure problem during the rolling process.
With no light changes during the roll you feel like the image shift -2stop smoothly then go up 2 stops, like you are playing with the iris ring going from 2.8 to 4/5.6 then to 2/1.4
Shutter speed 1/50
Lens 70-200mm canon
Samyang 35 mm and 85 mm
Iris 2.8
Iso 160
25fps
1920/1080p
Can anybody explain to me why this can happen?
Thanks,
E
