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.
Note: When the lens is used with the Nikon F-401/N4004*, the camera meter coupling function
does not operate and the exposure indicator LEDs do not appear.
*The Nikon N4004 is sold exclusively in the U.S.A.
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.
DEPTH OF FIELD
Depth of field can be checked with the color-coded depth-of-field indicators engraved
on the lens barrel.
If your camera has a depth-of-field preview function, it is possible to check the depth
of field in the viewfinder. (For details, see camera instruction manual.)
Depth of field can also be checked by referring to the table on page 31.
