Camera indicating means

Abstract

Disclosed are exposure data indicating means for an exchangeable lens type camera which is selectively settable for operation in either a diaphragm priority automatic shutter speed control mode or a shutter speed priority automatic diaphragm control mode and which includes structure enabling indication of an f-number representative of an automatically controlled diaphragm aperture when the maximum f-number of the particular exchangeable lens mounted on the camera has been preset. The indicating means provides an indication within a finder view field of both a preset f-number and a preselected shutter speed when the camera is set to operate in the automatic diaphragm control mode and of only a preset f-number when the camera is set to operate in the automatic shutter speed control mode. The indicating means includes a view-finder and two separate optical arrangements adapted for directing light to introduce visible information relating to set f-number and selected shutter speed into the view-finder view field. A shutter element coupled with a manually operated exposure mode selector is operable to block one optical arrangement and thereby prevent information relating to shutter speed from being introduced into the finder view field when the mode selector is operated to set the camera in its automatic shutter speed control mode.
