Thank you for your kind patronage of Nikon.

Before using your new lens, read the following carefully so you get the most out of your lens now and for years to come.

MOUNTING THE LENS A

To mount, position the lens in 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

Turn the focusing ring until the image in the viewfinder appears sharp and crisp. The effective focal length may vary in extreme heat or cold. To compensate for this, turn the lens focusing ring slightly beyond the °° (infinity) position.

Preset Focusing B

When you want to refocus rapidly to a specific object distance, preset the focused distance.

1.Loosen the preset-focus ring lock screw and turn the ring in either direction until it clicks.

2.Turn the focusing ring to set the desired distance.

3.Tighten the preset-focus ring lock screw.

It is possible to focus/refocus by turning either the preset-focus ring or focusing ring.
