Next, the state of the zoom-up switch ZUSW is detected (step S3). If the switch is ON, zoom-up is performed to change the focal length of the photographing lens 25a to the telephoto side (step S4).

When step S4 is completed, or in step S3, the zoom-up switch ZUS
When W is off, the zoom-down switch ZD
The state of the SW is detected (step S5).

Here, the zoom down switch ZDSW
Is on, zoom-down is performed to change the focal length of the taking lens 25a to the wide-angle side (step S).
6).

This step S6 is completed, or in step S5, the zoom-down switch ZDS
When W is off, 1st release switch 1R
The state of the switch is detected (step S7).

If the first release switch 1RSW is off, the process returns to step S1. If the first release switch 1RSW is on, the automatic focus adjustment process (AF) and the automatic exposure adjustment process (AE) are performed (step S1). S8).

Subsequently, a 2nd release switch 2RSW
Is detected (step S9), and if it is off, the process returns to step S1. If it is on,
The process (exposure) of exposing the subject image on the film 31b is performed by opening and closing the shutter after the lens barrel unit 25 is extended (step S10).

When the exposure is completed, it is determined whether or not the photographed frame is the last frame (step S11). If it is not the last frame, one frame is wound up (step S12), and the process returns to step S1. If it is the last frame, the film 31b is rewound (step S13), and the process returns to step S1.

If the barrier switch 46 is off in step S1, the power supply to each electric circuit is stopped and the main CPU 41 is put into a sleep mode (step S14).

In this stop mode, when the barrier switch 46 is turned on next time, the main CPU 41 returns from the sleep state by key-on wake-up or the like and exits the stop mode.

Here, the operation in the case of a zoom camera in which the focal length of the photographing lens is variable has been described. However, in the case of a camera in which the focal length of the photographing lens is fixed, the above steps S3 to S6 are performed. The operation is omitted.
