I don't know if this would be possible:
Sometimes I very much like to change the aperture during recording, adding a subtle effect of drama to some scenes. But the problem is, with a change of aperture the brightness changes too. Would it be possible to combine Iso-settings to aperture settings, so that there would be no blinking while changing the aperture, or to minimise blinking?
It would be so nice to change the depth of filed without any brightness flickering.
