Auto ISO Sensitivity Control In modes P, S, A, and M, auto ISO sensitivity control can be enabled or disabled by holding the S button and Sub-command dial rotating the sub-command dial. When auto ISO sensitivity control is enabled, ISO sensitivity will automatically be adjusted if optimal exposure cannot be achieved at the value selected with the S button and main command dial. To prevent ISO sensitivity going too high, you can choose an upper limit of from S button ISO 200 to Hi 2 using the ISO sensitivity settings > Maximum sensitivity item in the photo shooting menu. When auto ISO sensitivity control is enabled, the shooting display will show ISO AUTO. When sensitivity is altered from the value selected by the user, the altered value is shown in the display. D Auto ISO Sensitivity Control If the ISO sensitivity selected by the user is higher than that chosen for Maximum sensitivity when auto ISO sensitivity control is enabled, the value selected by the user will be used instead. When a flash is used, shutter speed will be restricted to values between the speed selected for Custom Setting e1 (Flash sync speed) and the speed selected for Custom Setting e2 (Flash shutter speed).
