Abstract

PURPOSE:To set distance information in the middle point of the object field depth or the flash exposure quantity, by storing range finding information of the plural objects and operating and processing the farthest and the nearest information, in the automatic focus adjusting camera. CONSTITUTION:Distance information detected by the operation of range finder 3 by the operation of release mechanism 1 is input to middle value operator 7. In examination for the object field depth, distance information is input to operator 7 through memory 19 by the output of focus memory 16; and if it is outside the object field depth determined the F value of the lens for the center value, the out signal is warned and displayed by display circuit 10. In the flashmatic mode, selecting device 37 is set to FM. Operator 7 operates the center value of the storobe exposure quantity output from memories 5, 19, 33, 34 and 35 and operates the iris value from strobe and film information.
