Abstract

PURPOSE: To let the information on the number of stopping-down steps be stored if a lens is mounted and is once set at the minimum aperture and exposure control and display be accomplished by associating a detecting means which detects that the iris has been set at the minimum aperture to the memory part.
CONSTITUTION: When a lens is mounted to the camera, rest means 21 actuated in cooperation to this, causing the content of a memory part 20 to be set. When at this time an aperture ring 1 is set at the minimum aperture value, an interlocking lever 5 and a sliding contact piece 4 both about against pins 3, 2 respectively and a sliding part 7 outputs the data corresponding to the maximum number of aperture steps to an arithmetic part 23, the data whereof are taken in the memory part 20 because a switch 6 is ON. The data having been taken do not change even if the aperture ring is set at values other than the minimum aperture value and therefore full-aperture value and set aperture value may be operated irrespective of the positions of the aperture ring 1.
