Shutter Speed Priority Setting
By selecting the S mode of the camera, you can set the shutter speed from 30sec. to 1/X sync speed.
When you set the desired shutter speed, the camera will select the appropriate aperture value for the
background. If the subject is too light or too dark, the aperture value indicator will blink and show the limit
values (maximum or minimum aperture). In such as case, the camera proceeds to take flash photograph at
the limit value. Thus, the main subject in the picture may be exposed correctly, but the background will
become under or over exposed.
Aperture Priority Setting

background. If the subject is too bright or too dark, the shutter speed indicator will blink and show the limit
highest or slowest shutter speed value. The highest shutter speed will be limited to the camera's normal
flash synchronization speed. In such a case, the camera proceeds to take a flash photograph at the limit
value. Thus, the main subject in a picture may be exposed correctly, but the background will become under
or overexposed.
When used with M Mode
You can set the desired shutter speed and aperture value. You can set the shutter speed from top sync
speed to bulb. If you adjust the exposure according to the exposure meter indication, the camera will work
