The focal plane shutter adjuster has a setting position in which the central shutter of the objective can be used for exposure settings. The objective shutter adjuster has a setting position, in which a lock (36) is operated to block the closure drive of the segment system of the objective shutter. The adjuster is locked in that position by a spring-loaded lever which is released by a push button.
