ISO Sensitivity

  • -button menu : ━
  • Movie-related controls :
  • Movie shooting menu :

When exposure mode P, S, or A is selected in movie mode, the camera adjusts ISO sensitivity automatically. You can, however, choose the upper limit to prevent the camera choosing too high a value. In exposure mode M, you also have the option of adjusting ISO sensitivity manually.

Exposure Modes P, S, and A

The camera adjusts ISO sensitivity automatically in response to shooting conditions, choosing from values of from ISO 64 to (at default settings) Hi 2. The current value is displayed in the monitor and control panel.

Exposure Mode M

When the camera is in movie mode, you can enable or disable auto ISO sensitivity control by keeping the button pressed and rotating the sub-command dial; the display shows ISO AUTO when auto ISO sensitivity control is enabled and ISO when it is disabled. When auto ISO sensitivity control is disabled, ISO sensitivity can be manually set to values between ISO 64 and Hi 2 by keeping the button pressed while rotating the main command dial. Current ISO sensitivity settings are displayed in the monitor and control panel.

ISO sensitivity can also be adjusted using the ISO sensitivity settings item in the movie shooting menu. Use Auto ISO control (mode M) to enable or disable auto ISO sensitivity control and ISO sensitivity (mode M) to choose the value used when auto ISO sensitivity control is disabled.

Maximum Sensitivity

To prevent auto ISO sensitivity control setting ISO sensitivity too high, you can use the ISO sensitivity settings > Maximum sensitivity option in the movie shooting menu to select an upper limit. Choose from values between ISO 200 and Hi 2. The selected setting applies in modes P, S, and A and when auto ISO sensitivity control is enabled in mode M.

Auto ISO Sensitivity Control

At high ISO sensitivities, the camera may have difficulty focusing and noise (randomly-spaced bright pixels, fog, or lines) may increase. This can be prevented by choosing a lower value for ISO sensitivity settings > Maximum sensitivity in the movie shooting menu.

Selecting an option other than Off for High ISO NR in the movie shooting menu reduces noise (randomly-spaced bright pixels), particularly in movies shot at high ISO sensitivities. Choose the amount of noise reduction performed from High, Normal, and Low, but note that edges may soften and the picture may lose definition at higher settings. If Off is selected, noise reduction will be performed only as required and never at an amount as high as when Low is selected.

Image Area
