C100 auto iris adjustment on zoom ...

Hi there,

On the rare occasions one has to zoom (using the slightly smoother action of a follow focus device for this purpose), how can I stop the C100's aperture from automatically 'clicking' and adjusting? Or is this all there is?

I look forward to hearing from you.

Found it. Zoom-Iris Correct switch.

What mode are you shooting in? I've never noticed an aperture click problem....

Go into the Camera Setup menu > Iris > Zoom-Iris Correct and turn it to off. That should fix it. I think that's a feature designed to correct for variable aperture Canon zooms.
