Abstract
An electromotive drive for swiveling the viewfinder mirror in a single-lens mirror reflex camera between its viewfinder position and its picture taking position. A balanced mirror drive includes a drive arm. The drive arm forms an integral component of the electromotive drive. The drive arm can be electromotively swiveled in about a fixed pivot axis lying parallel to the viewfinder-mirror swivel axis. The drive arm is kinematically coupled with the viewfinder mirror in such a way that the swiveling of the drive arm induces a swiveling in the opposite direction of the viewfinder mirror.
