Next, the operation of this embodiment will be described.

First, the photographing operation of the camera will be briefly described, and then the custom function will be described.

As shown in FIG. 1, based on the information sent from the lens CPU 41 to the CPU 1 of the body 31, the CPU 1
Performs AF control, AE control, and the like to perform a shooting operation process.

The light beam that has passed through the photographing optical system is partly transmitted by the main mirror 15 and the rest is reflected and guided to the finder system. The reflected light is detected by an automatic exposure sensor (AE sensor) 8 placed near the finder, and the output of the AE sensor 8 is calculated by the AE control unit 9 as an exposure value. This exposure value is transmitted to the CPU 1. CPU1
Captures this exposure value and sends a shutter speed command and / or an aperture command to the corresponding shutter control unit 10b or aperture control unit 10a in accordance with the set exposure mode. In response to this, the diaphragm control unit 10a controls opening / closing of the diaphragm 19 in the lens. Similarly, the shutter control unit 10b controls the shutter speed.

The sub-mirror 14 reflects the light flux transmitted through the main mirror 15 downward and makes it incident on the focus detection device 7 arranged below the body 31. Focus detection device 7
The defocus amount up to the object detected by
It is transmitted to PU1. In automatic focusing, this defocus amount is converted into a motor drive amount by the CPU 1 and output to the AF motor control unit 11 to drive the motor 12. The driving force of the motor 12 is transmitted to the lens 40 side via the gear 13 and the couplings 16 and 17, and the focusing lens group 20 is moved along the optical axis to focus.

FIG. 3 is a flow chart showing the flow of custom function processing in this embodiment.

In FIG. 3, first, the taking lens 40 is
As shown in FIG. 1, when the camera is mounted on the body 31 and the power supply 38 of the camera is turned on, the camera CPU 1 communicates with the lens CPU 41 through the lens contact, and the photographing lens 4
Upon receiving the information about 0, it becomes operable (step 1). Next, the CPU 1 sets the above-mentioned custom function setting /
It is checked whether or not the custom function is set on the display unit 2 (step 2). If not, the custom function is displayed. If so, go to step 3.
Here, whether or not the custom function setting is performed is checked by whether or not an operation is performed by the mode selection unit 5a and the mode setting unit 5b. Specifically, the mode selection button 3 in FIG.
By turning the command dial 33 while pressing 2, the mode can be changed to the custom function setting mode.

Next, the custom function is set and the setting contents are stored in the custom function storage section 6 (step 3). That is, by pressing the custom function selection button 34, the switch 3 or 4 of the custom function selection section 5c is turned on to select the custom function set in the camera,
It is determined whether to operate the selected custom function by operating the command dial 33. The selection is sequentially switched each time the custom function selection button 34 is pressed, as shown in FIG. The CPU 1 sets, for example, the setting / non-setting of the custom function every time the function is selected, the custom function storage unit 6
Send to and have it memorized. That is, the storage unit 6 determines whether or not each of the customizable functions is set,
If set, information about which switch of the custom function selection unit 5c works is stored.

Further, the CPU 1 displays the set custom function by the setting custom function display section 21 both when the setting of the custom function is completed and when the custom function is not set. It is displayed in the window 35 and / or the finder 36 (step 4). Whether or not to operate the displayed custom function is selected, for example, by displaying ON and OFF. If it is ON, the function is activated and O
If the display is FF, it indicates to the photographer that the function does not operate.

By the above operation, the custom function is set. The details of this custom function setting will be described later.

Next, the operation at the time of photographing will be described.

The CPU 1 monitors the operation of the camera from the outside. Here, it is monitored whether or not the switch (SW1) 3 of the custom function selection unit 5c is turned on (step 5). When turned on, the operation of the custom function set in the switch (SW1) 3 is executed (step 6). In the case of this embodiment, if all the custom functions of the switch (SW1) 3 are set, the switch (SW1) 3
1) When 3 is ON, the AE lock function works at the same time when the AF operation starts. On the other hand, when an operation for photographing is performed while the switch (SW1) 3 is not turned on, normal photographing processing is performed (step 11) and the process returns (step 12).

Next, the CPU 1 uses the switch (SW2) 4
Is checked (step 7). If on,
The function set for the switch (SW2) 4 is executed (step 8). Since the switch (SW1) 3 is turned off at the same time that the switch (SW2) 4 is turned on, the custom function set by the switch (SW1) 3 does not operate. In this embodiment, when all the functions are set by the switch (SW2) 4, the AE lock holds the setting by the switch (SW1) 3, and the focus lock and the narrowing function operate simultaneously. Thereafter, the photographer presses the shutter button 37 to complete the photographing (step 9) and return (step 10). On the other hand, if an operation for shooting is performed while the switch (SW2) 4 is not turned on, shooting processing is performed (step 13) while the custom function set by the switch (SW1) 3 is operating. Return (step 14).

With the above operation, the custom function can be operated at the time of photographing. The details of the operation of the custom function at the time of shooting will be described later.
