Changing the ISO Speed or Gain Value

  1. Select MENU > [ Camera Setup] > [ISO/Gain] > [ISO] or [Gain].
  2. Depending on your previous selection, select MENU > [ Camera Setup] > [ISO Increment] (ISO speed) or [Gain Increment] (gain).
  3. Select the desired option.
  4. Adjust the ISO speed or gain value using the direct setting mode.
    • After closing the menu, press the ISO/GAIN button to highlight the ISO speed or gain value.
    • The selected ISO speed/gain value will appear at the bottom of the screen.


Using the Control Dial

You can also adjust the ISO speed or gain value using the control dial on the camera or the one on the camera grip. You will need to set in advance the function of one of the control dials to [ISO/Gain]. You can select the function assigned to each control dial independently.
  1. Select MENU > [ System Setup] > [Camera Ctrl Dial] (control dial on the camera) or [Camera Grip Ctrl Dial] (control dial on the camera grip) > [ISO/Gain].
  2. After closing the menu, turn the control dial assigned to [ISO/Gain] to set the desired ISO speed or gain value.
    • To select whether to change the ISO speed or the gain, perform step 1 of the previous procedure.

 NOTES

  • When high ISO speeds or gain levels are set, the picture may flicker slightly.
  • When high ISO speeds or gain levels are set, bright red, green or blue dots may appear on the screen. In such case, use a faster shutter speed or select a lower ISO speed or gain value.
  • When the ISO speed or gain level is changed, some noise may appear momentarily on the screen. Do not adjust the ISO speed/gain level while recording.
  • You can use the MENU > [ System Setup] > [Camera Ctrl Dial Dir.] or [Camera Grip Ctrl Dial Dir.] setting to change the direction of the adjustment when you turn the control dial on the camera or on the camera grip, respectively.
  • When an optional RC-V100 Remote Controller is connected to the camera, you can adjust the ISO speed or gain value with the remote controller's ISO/GAIN  buttons.
