By going through this cycle you can see the whole of the dynamic range that the camera is recording.

Press the assign button 2 a third time and will return to normal.

CineEI and Exposure index

EI = Exposure Index, this allows you to rate the cameras ISO to alter the midpoint of the dynamic

rate. The cameras native setting is 2000 ISO. Changing the EI doesn't change the recording ISO

but changes how affective it is.

To adjust the EI you use the gain switch on the left hand side but you want the gain/EI high, medium

and low settings to be less than the native 2000 ISO to get the best image. To change time, go to

Menu > Camera > ISO/Gain/EI and change the setting to be high at 2000/6.0 E, medium to be

1000/5.0 E and low at 500/4.0 E

Recording at 2000 ISO can effect grading where it produces too much noise. EI does not change

the sensitivity of the camera it only effects the MLUT. Halving the ISO = minus 1 stop, doubling the

iso = plus 1 stop. Stopping the EI down and opening the aperture to expose your image so the

camera is still recording at 2000 iso your image is brighter so when you go into post you bring your

levels down reducing the noise and a clear image. It does have cons that some highlights maybe

over exposed but you can see more into the shadows. Use 1000EI or 800EI for most general filming.
