Abstract

The invention relates to an optical system for the rotation of images taken by a film camera about an optical axis, having a controller device for the rotation of images with an adjusting motor and a position sensor for recording the rotation angle of the image-rotating optical system. In addition, the possibility of displacing the optical system in at least one axial direction is provided.
