DIAPHRAGM SETTING
Set the shutter speed dial at "AUTOMATIC".
Rotate the diaphragm ring to pre-select the
desired aperture such as follows:
Fine weather……………..f/8 - f/11
Cloudy weather………….f/4 - f/5.6
Indoor……………………f/2 - f/2.8
This is a rough guide to acquaint you with the
automatic shutter operation. As you get used to
it, you will have your own yardstick for aperture
pre-selection depending on your subject and
lighting conditions.
The shutter speed of the ES is automatically
determined at any speed within the range of 8 to
1/1000 sec. according to the brightness of your
subjects.
