You can set the shutter to the speed at which you want to shoot. The camera
will set the appropriate aperture value for the shutter speed you set.

● Turn the Ï ring to set the shutter speed.
Shoot.
Available Shutter Speeds
• 2" indicates 2 seconds, 0"3 indicates 0.3 second and 1/160 indicates 1/160
second.
• The fastest shutter speed when using the flash is 1/500 second. The camera
automatically resets the shutter speed to 1/500 second if a faster speed is
chosen.
• Depending on the zoom position, some shutter speeds may not be available.
If the aperture value displays in orange when the shutter button is pressed
halfway, the scene has exceeded the correct exposure limits. Adjust the shutter
speed until the aperture value displays in white. Safety shift can also be used
(p. 96).

What if aperture value is displayed in orange?
• When shutter speeds of 1.3 seconds or slower are used, images are
processed to eliminate noise after being taken. A certain amount of
processing time may be needed before you can take the next shot.
• It is recommended to set the [IS Mode] to [Off] when lowering the shutter
speed and shooting with a tripod (p. 153).
