Abstract
PURPOSE: To enable the selection of whether the automatic light dimming signal is obtained by the light dimming photo detector on the strobe side or the automatic light dimming signal is obtained by the photo detector for TTL photometry on the camera side to be made simply through changeover operation on the camera side.
CONSTITUTION: The electric circuit encircled by the alternate long and two short dashes line belongs to the electric shutter camera of TTL photometry system and is so constituted that the electric shutter closing signal having the photometric circuit for automatic exposure capable of measuring the flash light of strobe is fetched out as the dimming light of the auto strobe and is supplied to the auto strobe. When the strobe is mounted to this camera and thd camera is set to the auto photographic mode through TTL photometry by changing over a photographic mode selecting changeover switch 300 to the stationary terminal 300a, a trigger switch 79 is not fired even if the photo detector 92 on the strobe side reaches the specified quantity of light owing to reflection from the subject, thus the light dimming operation is preferentially accomplished by the light dimming operation signal from the camera side.
