Camera Functions

Auto ISO Sensitivity Control

Auto ISO sensitivity control lets the camera adjust ISO sensitivity automatically if optimal exposure can not be achieved at the value selected by the user.

Maximum sensitivity: Choose the maximum ISO sensitivity to prevent auto ISO sensitivity control selecting too high a value.

Minimum shutter speed: Auto ISO sensitivity control will automatically raise ISO sensitivity to prevent shutter speeds slower than this limit in exposure modes P and A. Choose a value, or select Auto to allow the camera to choose the minimum shutter speed according to the lens focal length (CPU lenses only). For example, the camera will select a fast minimum shutter speed with telephoto lenses to reduce the camera blur that tends to occur at long focal lengths.
