● Press the [ ] button, press the [ ][ ]
buttons to choose an option, and then
press the [ ] button.
● The option you configured is now
displayed.
● To view the automatically determined ISO speed when you have
set the ISO speed to [AUTO], press the shutter button halfway.
● Although choosing a lower ISO speed may reduce image
graininess, there may be a greater risk of subject and camera
shake in some shooting conditions.
● Choosing a higher ISO speed will increase shutter speed, which
may reduce subject and camera shake and increase the flash
range to reach up to the distant objects; however, in this case,
images will look grainy.
