PURPOSE:To obtain an inexpensive, high-accuracy power switching device by adjusting a fiber optical system associatively with power adjusting operation and adjusting the power of a photographic optical system to set finder power associatively with photographing operation. CONSTITUTION:When a switching member 6 is operated over a look in a finder so as to change power in a wide state, viewfinder lens systems 4.5.5c operate associatively with the motion to change finder power, and photographic optical systems 10d.15b are so adjusted as to correspond to the set finder power associatively with releasing operation. Consequently, a compact, energy-saving camera which has good operativity and good light shielding is obtained as what is called a lens shutter camera which has a finder optical system and a photographic optical system independently and is capable of zoom photography while including plural focal length switching.
