PURPOSE:To cover a delay in the response of a range-finding means by making a driving device actuate according to a trigger signal generated from a camera when an object exists in a previously set distance. CONSTITUTION:When the object is exists in the previously set distance, the trigger signal is generated from the camera and the driving device is made to actuate according to the trigger signal to make correction optical systems respectively move in biaxial direction where planes perpendicular to an optical axis are orthogonally crossed at desired speeds. namely, when the object enters any one of the focusing areas 11A1, 110 and 112 of a finder 66, which is the previously set distance, a release signal 623 is generated by an OR circuit 15 and the AND circuit 632 of a release 631. Thus, the deviation from the center of composition of the object can be removed, which is caused by the delay in the response of an object in focusing area discrimination circuit. |
