CAMERA
Document Type and Number:
Japanese Patent JPS54111341
Kind Code:
A
Abstract:
A photographic or cinematographic camera, in particular with a pancratic (zoom) objective lens and a comparator for comparison of the desired setting e.g. of the near point (punctum proximum) and of the far point (punctum remotum) of a camera space and of the actual setting e.g. of the depth of focus, the desired setting being adjusted by means of presetters, the actual setting resulting from the actual setpoints of the objective lens, such as range, diaphragm and under circumstances focal length, the comparator being formed preferably by an electrical linkage device, whereby upon differences between the desired setting and the actual setting, a signal can be released, which signal can be fed to an indicator device, and respectively, or to a control device. A memory device is provided in which all setpoints (which are necessary for a plurality of settings) and/or limit values of objective lens settings are stored in several memory sections which are associated with different desired value ranges. The presetters are connected with a selection device for at least one memory section, whereby that memory section which corresponds to the preset desired value is connectable with a comparator.
