A release button 10, a power switch 11 and the like are provided.

When the setting dial 2 is rotated while pressing the exposure mode setting button 3, the exposure modes are the program mode (P), the shutter speed priority mode (S), the aperture priority mode (A), and the manual mode (M) in this order. By switching, selecting a desired exposure mode and releasing the setting button 3, the exposure mode is set. Further, when the setting dial 2 is rotated while pressing the film feeding mode setting button 4, the film feeding mode is switched to the high-speed winding mode and the low-speed winding mode, the desired film feeding mode is selected, and the setting button 4 is pressed. When opened, the film feeding mode is set. The film sensitivity is normally automatically set using the DX contact, but when the sensitivity is intentionally set, it can be set to a desired sensitivity by rotating the setting dial 2 while pressing the film sensitivity setting button 5. Further, when it is desired to perform exposure by superimposing on one film, the desired number of multiple exposures can be set by rotating the setting dial 2 while pressing the multiple exposure setting button 6.

FIG. 5 shows an in-viewfinder display. The indicator 14 in the finder also has indicator lamps 21a to 27a showing the selected program diagram similarly to the indicator lamps 21 to 27 of the C section of the external indicator 9.

FIG. 6 shows an example of a program diagram stored in the memory of the camera body 1 during non-flash photography. In the figure, the vertical axis indicates the aperture F, the horizontal axis indicates the shutter speed T, and the diagonal axis indicates the Ev value (ISO10
(At 0). When the portrait mode is selected and the indicator lamp 21 is lit, the aperture F and the shutter speed T according to the brightness Ev value of the subject are set according to the program diagram 31. The shutter speed T = 4 to 1/15 and the aperture F = 2.8 are set for the brightness of the subject Ev1 to 7, and the shutter speed T = 1/15 for Ev7 to 19,
Aperture F = 2.8 to shutter speed T = 1/1000,
The shutter speed and the aperture on the line up to the aperture F = 32 are set. As a result, in portrait mode, an image effect is obtained in which the background is blurred and the person is highlighted.

When the landscape mode is selected and the indicator lamp 24 is lit, the aperture F and the shutter speed T are set according to the brightness Ev value of the subject according to the program diagram 32. With Ev5 to 18, shutter speed T = 15 to 1/5

Then, shutter speed 1/1000, aperture F = 2.8-2
2 is set. As a result, in the sports mode, a stop motion effect of stopping a momentary motion can be obtained.

When the close-up mode is selected and the indicator lamp 27 is lit, the aperture F and the shutter speed T are set according to the brightness Ev value of the subject according to the program diagram 34. Shutter speed T = 15 to 1/2 for Ev4 to 16
50 and aperture F = 16 are set, and in Ev16 to 19, the shutter speed T and aperture F are set as in the program diagram 31 described above. As a result, in the close-up mode, a sharp image effect with a relatively deep depth of field can be obtained while the subject is close-up.

The pan focus mode is selected and the indicator lamp 2 is selected.
When 3 is lit, the aperture F and the shutter speed T according to the brightness Ev value of the subject according to the program diagram 35.
Is set. Shutter speed of 15-in Ev2-12
1/60 and aperture F = 8 are set, and in Ev12 to 19, shutter speed T and aperture F are set as in the program diagram 31 described above. This makes it possible to obtain a photograph in which not only the subject but also the background are in focus in the pan focus mode, which is particularly effective for commemorative photographs.

When the silhouette mode is selected and the indicator lamp 25 is lit, the aperture F and the shutter speed T are set according to the brightness Ev value of the object according to the program diagram 34. As a result, in the silhouette mode, for example, an image effect in which the silhouette of the subject is coordinated against the sunset is obtained.

When the red-eye reduction mode is selected and the indicator lamp 22 is lit, the aperture F and the shutter speed T are set according to the brightness Ev value of the object according to the program diagram 31, and the strobe light is preliminarily emitted. . As a result, it is possible to prevent the eyes of a person from becoming red when the person uses a strobe at the night for flash photography.

FIG. 7 shows an example of a program diagram stored in the memory of the camera body 1 during flash photography. In the figure, the vertical axis represents the aperture F, the horizontal axis represents the shutter speed T, and the diagonal axis represents the Ev value (ISO100) indicating the brightness of the subject.
In). Normally, when the program mode (P) is set, the aperture F and the shutter speed T according to the brightness Ev value of the subject are set according to the program diagram 30. With Ev9-11, shutter speed T = 1 / 30-
1/125 and aperture F = 4 are set, and in Ev11 to 16, shutter speed T = 1/125 and aperture F = 4 to 22 are set.

When the portrait mode is selected in flash photography, the aperture F and the shutter speed T are set according to the brightness Ev value of the subject according to the program diagram 31 '. With Ev8-10, shutter speed 1 / 30-1 /
125 and aperture F = 2.8 are set, and in Ev10 to 16, shutter speed 1/125 and aperture F = 2.8 to 22 are set. As a result, in stroboscopic photography in portrait mode, the image effect of blurring the background and making the person stand out can be obtained.

The aperture F and the shutter speed T are set according to the value. E
In v5 to 16, shutter speed T = 15 to 1/125,
The diaphragm F = 22 is set. In the conventional stroboscopic photography, the stroboscopic photography is performed according to the program diagram 30, and when the brightness of the subject becomes dark, the aperture does not change to the open side, and since the background is usually far away, the stroboscopic light does not reach and the exposure is underexposed. Moreover, a sharp image effect with a deep depth of field could not be obtained. In this embodiment, since a low shutter speed of up to 15 seconds can be set, the background is properly exposed and a sharp image effect can be obtained.

When the sport mode is selected in the flash photography, the aperture F and the shutter speed T corresponding to the brightness Ev value of the subject are set according to the program diagram 33 'similar to the program diagram 31' described above. . As a result, a stop motion effect of stopping a momentary motion is obtained in stroboscopic photography in the sports mode.

25, diaphragm F = 16 is set, and in Ev15 to 16, shutter speed T = 1/125 and diaphragm F = 16 to 22 are set. As a result, in stroboscopic photography in the close-up mode, a sharp image effect with a relatively deep depth of field can be obtained even when the subject is close-up.

When the pan focus mode is selected in stroboscopic photography, the aperture F and the shutter speed T according to the brightness Ev value of the subject are set according to the program diagram 35 '. Shutter speed 15 to 1/1 for Ev2 to 13
25, diaphragm F = 8 is set, and shutter speed 1/125 and diaphragm F = 8-22 are set for Ev13-16. In the conventional stroboscopic photography, the stroboscopic photography is performed according to the program diagram 30, and when the brightness of the subject becomes dark, the aperture does not change to the open side, and since the background is usually far away, the stroboscopic light does not reach and the exposure is underexposed. In addition, I couldn't get a good picture from the subject to the background.
In flash photography in the pan-focus mode of this embodiment, a low shutter speed of up to 15 seconds can be set, so that the exposure is appropriate and a sharp image effect can be obtained from the near view to the background.

Since a silhouette cannot be obtained in stroboscopic photography in the silhouette mode, it is desirable to prohibit stroboscopic photography in this mode. In red-eye reduction mode, flash photography is always performed.
