ABSTRACT:
A camera includes: a spring urging a diaphragm adjusting member, which is capable of being set to a desired aperture position, to either one of maximum and minimum aperture setting positions; an automatic flashmatic mode setting member operable upon the mounting of a flash means on a camera; and the flashmatic member interlocking a focus adjusting member with the diaphragm adjusting member in such a manner that a diaphragm aperture may be set commensurate with an object-to-lens distance set by the focus adjusting member. The mounting of the flash means causes the diaphragm adjusting member to return to such one aperture setting position under the action of a spring so as to establish the flashmatic mode, wherein a diaphragm aperture may be automatically adjusted commensurate with an object-to-lens distance.
