Abstract
A camera having a standard taking lens and a macro lens which are held in a lens holder rotatable in a plane perpendicular to the photographic light path, whereby either one of standard and macro lenses can be inserted selectively into the light path. The macro lens is smaller in diameter than the standard lens so as to distinguish the lenses from each other during manufacture and assembly. When the macro lens is placed in the photographic light path, switching means turns a charge switch on, thereby to charge a main condenser for flashing. In macrophotography, upon depression of a shutter release button, flash light is automatically emitted.
