Hi,
I'm shooting a short in a couple of weeks on a Z1 (I have used it on one other shoot).
A curious thing I've noticed during indoor tech rehearsals is that when the camera is zoomed to infinity (e.g. when I'm setting focus), the iris closes slightly (F2.8) towards the end of the zoom, even with all settings locked: Gain (0), Iris (F1.6), and Shutter Speed (1/50).
It doesn't appear to be reacting to light, as the same thing happens in bright and dark environments.
Anyone know why this might be the case?
