We are using a photo lens on a Blackmagic Ursa on the Movi Pro. Since the photo lens does not have an iris ring, we are using an external Arduino to control iris via the camera electronics. Is it possible to either read the position of the iris wheel via the Aux Data Out port on the Movi Controller? Or even better, is it possible to read the iris state from the Movi COM port and pass it to the camera via the Arduino (even without a motor hooked up to the Movi)? Does anyone have any experience with this?
