A mirror arrangement for reflex cameras is provided. A main mirror is pivotably connected to a steering lever, which is rotatable about a rotary spindle, such that the main mirror is pivoted and lowered during transition into the lower position. A secondary mirror is rotatably mounted to a housing via a pivot arm that is arranged pivotably about a rotary spindle that is fixed to the housing. The rotary spindle of the pivot arm is parallel to the rotary spindle of the steering lever. The mirror arrangement further comprises an actuating lever, which is connected to the main mirror and the pivot arm of the secondary mirror. The actuating lever is configured to provide simultaneous movement of the main mirror and of the secondary mirror from the upper position into the lower position and vice versa.
