PURPOSE:To know the state of the body side of a single-lens reflex camera on its image blurring preventing device side and to perform proper processing according to the state by detecting the start or end of a communication between the camera and a lens and controlling the driving means for an optical system. CONSTITUTION:When the shutter release button is pressed in and a switch 17 turns on, a body CPU 14 starts stop control to stop down a stop 9 to a specific aperture value and a switch 31 which is associated with a stop interlocking lever 10 is turned on. At this time, analog switches 28 and 29 are both on and image blur preventing operation is in process. A latch 25 is reset by turning on the switch 31 and the output of an integrator 3 is disconnected from an operational amplifier 7, so centering operation is carried out by a reference power source for centering. When an image formation array 4 comes to the center of a stroke and the centering is completed, the latch 25 is set and the output of the integrator 3 is applied to the operational amplifier 7 to restart image blurring preventing operation. |
