Cautions: Auto ISO Sensitivity Control
• At high ISO sensitivities, "noise" (randomly-spaced bright pixels, fog, or lines) may increase. Noise can be
reduced by selecting [High], [Normal], or [Low] for [High ISO NR] in the video recording menu (0 28).
• At high ISO sensitivities, the camera may have difficulty focusing.
• The foregoing can be prevented by choosing a lower value for [ISO sensitivity settings] > [Maxi-
mum sensitivity] in the video recording menu.
• The minimum values available for [Maximum sensitivity] and [ISO sensitivity (mode M)] when
[HLG] is selected for video tone mode are ISO 800 and 400, respectively.
• The minimum values available for [Maximum sensitivity] and [ISO sensitivity (mode M)] when
[N-Log] is selected for video tone mode are ISO 1600 and 800, respectively.
