Abstract

PURPOSE: To increase the degree of freedom of optical system and enable the lens suited for zone focusing to be selected by making selective use of plural different lenses.
CONSTITUTION: Winding the film causes the shutter to be charged and also causes a lens base 6 to turn counterclockwise against a spring 7 and to be locked by a stopper 8. When the release button is pushed, the stopper 8 turns about an axis 9, causing the lens base 6 to be unlocked and to turn subsequently clockwise by being pulled by the spring 7. A switch piece 11, which is fitted to the lens base 9, makes contact subsequently to the stationary lens base position detecting electrodes 12 thru 15 along with turning of the lens base 9, whereby which of interchangeable lenses 1 thru 4 is to be used as the photographic lens system is detected.
