EXPOSURE MODE AND BUILT-IN FLASH
P mode
Depending on the brightness of the subject, the most appropriate shutter speed
(between 1/60～1/180 sec) and aperture will be selected.
In bright situations, the flash will be “daylight synchronization flash”, and the camera
will calculate the appropriate flash amount for the correct exposure, of both the
subject and background. If the ambient light is too great, resulting in overexposure,
the shutter speed and aperture value displays will blink. If the subject is too dark, the
camera will proceed to take a flash exposure with the aperture fully open.
A mode
Use this mode if you want to set the desired aperture value. The camera will select
the appropriate shutter speed for the background. The shutter speed will operate at
1/180 or slower. In bright situation, the camera will work the same as P mode for
daylight synchronization flash and it can obtain a balanced exposure between the
subject and background. If the maximum synchronized shutter speed is displayed
and is blinking, please set the aperture value to a smaller aperture value (large
F-number). If the subject is too dark, the flash will use slow synchronization.
S mode
Use this mode if you want to set a specific shutter speed. The camera will select the
appropriate aperture value for the background. The shutter speed will operate
between 1/180 or slower. The camera will automatically correct the shutter speed to
the highest synchronization speed even if you select a higher shutter speed. If the
subject is too bright, the flash will be set to daylight synchronized. Then you can
obtain a balanced exposure between subject and background. When the lens
smallest aperture (largest F-number) value is blinking, the picture will be
over-exposed. If the subject is too dark, the camera will display the largest aperture
value (small F-number) blinking, but the flash will operate with correct exposure.
M mode
This mode enables you to set both flash synchronized speed and aperture value. If
you set a synchronized speed faster than 1/180, the shutter speed will be set
automatically to 1/180. If the exposure meter indicates appropriate number, you will
obtain the correct exposure for the subject and background. If the exposure meter
indicates minus (under), you will obtain the correct exposure for subject, but the
background will be dark. If the exposure meter indicates plus (over), both the subject
and the background may be over-exposed.
CAUTION !!
•
When P and A modes are showing the shutter speed as 1/200sec., the
actual shutter speed value is 1/180sec. In the case of S and M modes,
please select 1/200sec., if you wish to set the shutter speed to 1/180sec.
•
If the flash is set on the wireless mode, the shutter synchronized speed will be
set automatically to 1/60 second. Please refer to the wireless mode page 45.
