In [ ] mode, you can set your preferred aperture value before shooting. In this case the camera automatically adjusts the shutter speed to suit your aperture value. In [ ] mode, you can set both your preferred shutter speed and aperture value to obtain the desired exposure.

Blurred motion (Slow shutter speed)

Frozen action (Fast shutter speed)

Blurred background (With a low aperture f/number)

Sharp foreground and background (With a high aperture f/number)

Setting the Shutter Speed ([Tv] Mode)

1. Press the power button to turn the camera on.

2. Set the mode dial to [ ].

3. Turn the <> dial to set the shutter speed.

IMPORTANT

  • With shutter speeds of 1.3 seconds or slower, there will be a delay before you can shoot again, as images are processed to remove noise.
  • When shooting at low shutter speeds on a tripod, you should set [IS Mode] to [Off].
  • Maximum shutter speed with the flash is 1/2000 second. If you specify a faster speed, the camera will automatically reset the speed to 1/2000 second before shooting.
  • Orange display of aperture values when you press the shutter button halfway indicates that the settings deviate from standard exposure. Adjust the shutter speed until the aperture value is displayed in white, or use safety shift.
  • Images shot at high ISO speeds may look grainy.

NOTE

  • [ ]: Time value
  • To avoid exposure problems in [ ] and [ ] modes, you can have the camera automatically adjust the shutter speed or aperture value, even when standard exposure cannot otherwise be obtained. Press the <> button and set [Safety Shift] on the [ ] tab to [On]. However, safety shift is disabled when the flash fires.

IMPORTANT

  • After you set the shutter speed or aperture value, the exposure level may change if you adjust the zoom or recompose the shot.
