Abstract
A mirror-reflex camera is provided having a viewfinder mirror which can be displaced between a viewing position and a taking position, and an electromagnetic drive for adjusting the viewfinder mirror. The viewfinder mirror can be displaced linearly between the viewing position and the taking position to ensure the quick and reliable adjustment of the viewfinder mirror between the viewing position and taking position, with a relatively low outlay and little expenditure of energy. The electromagnetic drive has a permanent magnet arrangement and a linearly displaceable plunger coil arrangement. The viewfinder mirror is displaceable, in particular, via a driver with the plunger coil arrangement.
