A camera has a housing accommodating a shutter release element, and a detachable handgrip on the housing which is turnable about a pivot axis extending transverse to the optical axis. A trigger element is integrated in the handgrip and a coupling is provided which, on depressing of the trigger element, will operate the shutter release element irrespective of the position which the handgrip assumes relative to the camera housing on being turned about the aforementioned pivot axis.

Camera

The grip part proper is angularly adjustably connected to a head carrying the camera whereby the grip axis and the axis of rotation are inclined to each other and the latter is inclined to the center axis of the head. The correspondingly oblique interface is additionally used to hold an adjustable ring carrying a camera release switch.

Camera grip

The shutter in front of the image aperture is constructed from two pairs of flaps which fold and unfold and are actuated by levers so that flap edges move as leading and trailing edges of a slit across the aperture. The flaps fold temporarily into the space occupied, for example, by a fold-up mirror prior to exposure if the camera is of the single reflex type.

Shutter for photographic cameras

A single lens mirror reflex camera arranged for very fast operation. Both the reflex mirror and the auxiliary shutter or protecting flap are moved very quickly from viewing position to picture-taking position, without jar or vibration, by means of separate operating linkages which are in an angular position while the mirror and flap are in viewing position, and which straighten out to straight-line or dead-center positions as the mirror and flap move to picture-taking position, thus bringing them to a smooth stop. A step-by-step electrical switch controls various functions of the camera at various step positions of the switch. One step initiates the running of an electric motor which serves both to wind the film in the camera and to restore the mirror and auxiliary shutter from picture-taking position to viewing position.
