Abstract:
1. An apparatus for adjusting the picture definition on a camera lens of a motion picture camera using a drive unit connected to the camera lens with an operating unit, which operating unit has a picture definition handwheel, which outputs control signals for manually adjusting, readjusting or delimiting an adjustment range of a picture definition to the drive unit, and a scale dial for displaying an adjusted picture definition and/or the delimited adjustment range of the picture definition, with an auto-focusing device for measuring the distance from an object to be recorded by the motion picture camera and outputting control signals to the drive unit for controlling the picture definition as a function of the measured distance from the object to be recorded, and with an electromechanical actuator of the operating unit for adjusting or readjusting the picture definition adjusted on the picture definition handwheel or displayed on the scale dial as a function of the control signals output by the auto-focusing device, wherein the scale dial comprises a scale dial which can be written on, whose position in relation to a reference position can be varied as a function of the control signals output by the auto-focusing device, and wherein the scale dial can be connected to stops for delimiting the picture definition adjustment range, whose position on the scale dial can be varied as a function of the control signals output by the auto-focusing device.
