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.

Abstract: The invention relates to an optical system (3) for the rotation of images taken by a film camera (2) about the optical axis, comprising a controller device for the rotation of images with an adjusting motor (8) and a position sensor (9), for recording the rotation angle of the image-rotating optical system (3). In addition to the rotation or tipping of the image about two axes, the possibility of displacing the optical system (3) in at least one axial direction is provided.

Abstract: The invention relates to a drive unit for the adjustment of the zoom, focus or iris ring of a camera lens. According to the invention, the drive unit comprises a drive shaft arranged parallel to the axis of the camera lens, a pin and groove arrangement for allowing axial displacement of the drive shaft, a pinion connected to the drive shaft and coupled to the external teeth of a lens ring of the camera lens, and two circular flanges connected to the drive shaft and for embracing a sector of the lens ring to pull along the drive shaft and the pinion as the lens ring moves axially. The invention creates a drive unit which allows adjustment of a lens ring even if the lens ring is displaced axially.
