ABSTRACT:
A photographic camera having an objective incorporating an electrodynamic driving system for the diaphragm system, and also having a selector adjustable for a manual or automatic mode, in which the driving member for the diaphragm blades has a path limiting stop associated therewith which is selectively variable in its basic position by a manually operated diaphragm preselector ring, and which stop, in the manual mode, cooperates with a counterstop pin on the driving member to determine the correspondingly manually preselected position of the diaphragm blades, e.g. following shutter release on a camera with full aperture viewing, but which stop, in the automatic mode, is not utilized.
