Some lenses or lens and teleconverter combinations can be difficult to focus manually. The following procedure disconnects the body’s AF system to make focusing easier (SMOOTH FOCUS). Metering accuracy and Anti-Shake performance is lower when using the function. This cannot be used with xi series or AF Power Zoom lenses. 1 Turn the focus-mode dial to the manual-focus position. 2 Simultaneously press and hold the lens release and the central button of the controller. Release the lens release followed by the controller to disconnect the AF system. 3 An indicator warns the smooth-focus mode is active. To cancel the mode, repeat the procedure or change the position of the focusmode dial.
