MOUNTING THE LENS
To mount, position the lens on the camera’s bayonet mount, lining up the aperture index on the lens with the
lens mounting index on the camera. Twist the camera body clockwise until it clicks into place.
To remove, press the lens’ release button on the camera and turn the camera body counterclockwise. For
details, refer to the camera's instruction manual.
FOCUSING
When used with a Nikon F4-series camera, this lens not only lets you choose between autofocus or manual
focusing, but also enables quick switching between autofocus and manual (autofocus with manual priority)
by presetting the focus mode ring to the M/A position. With other cameras, only manual focusing is
available. See chart below to determine appropriate focus mode.
