摘要： In the disclosed moving picture camera with an adjustable rotary shutter, the shutter has a rotary shutter and an adjusting blade. The shutter adjusting blade is adjustable coaxially to the rotary shutter, which adjusts a shutter aperture angle. A transmission and a positioning motor adjust the adjusting blade relative to the rotary shutter. A potentiometer is connected to the shutter adjusting blade and to the rotary shutter, for measuring the position of the shutter adjustment blade in relation to the rotary shutter. The potentiometer generates a position signal indicating the actual position of the shutter adjustment blade in relation to the rotary shutter.
