Abstract
PURPOSE:To obtain a zoom camera which is dedicated to a shutter chance by installing an object distance detecting means, photographing magnification setting means and focal distance operating means. CONSTITUTION:A focus motor driving circuit 3 drives a motor 4 with the rotating quantity signal of a processing device 1 so as to move a focusing lens LF and an encoder 5 monitors the rotation of the motor and counts pulses so as to stop the driving when the counted pulses becomes a specified value. A zoom motor driving circuit 7 drives a motor 8 with the signal of the device 1 so as to move zoom lenses LZ1 and LZ2. The encoder by a brush BR and a code plate CD transmits the position code of an operation part 9 to a storage part 10 and the manipulated quantity conversion information of other image pickup lens and the focal distance information of telephoto and wide ends, etc., which is corresponding focal distance information is transmitted to the processing device 1. When autoprogram operation is selected through an operation part 11 the magnification in accordance with the object distance is set and the focal distance of a specified magnification is operated, so that proper zooming can be possible and a user can dedicates to the shutter chance.
