A range switch lets you select a focusing range of either ..6m / 1.9 ft. to infinity or 1m/3.3 ft. to infinity, depending on shooting conditions. This setting can reduce the actual auto focusing time.

Make sure to switch the focusing range only when the focusing distance indicator reads more than .6m.

If the lens is set closer than .6m and then switched to the 3m to infinity range and focused on a distant subject in AF focusing mode, the lens may stop briefly at the 1.6m position. This is not a problem with the lens. Simply press the shutter button again.
