Attachment and Removal
Attachment and Removal
Attaching the Lens
z
Turn the camera off , remove the body cap, and detach the rear lens cap.
x
Position the lens on the camera body, keeping the mounting mark
on the lens aligned with the mounting mark on the camera body,
and then rotate the lens counterclockwise until it clicks into place.
c
Turn the camera on.
• The lens will extend automatically.
D
Extending the Lens
• Do not place the camera on a surface with the lens pointing
down. Be particularly careful not to turn the camera on while
it is resting on the lens, as the lens may malfunction if it fails
to extend.
• Do not hold the telescoping section or attempt to forcibly ex-
tend or retract the lens. Failure to observe these precautions
could result in product malfunction.
• If the lens does not extend or freezes in place once extended, press the shutter-release button.
Removing the Lens
z
Turn the camera off .
• The lens will retract automatically. Proceed to Step 2 after confi rming
that the lens is fully retracted.
x
Press and hold the lens release button while turning the lens clockwise.
D
Removing the Lens While It Is Extended
The lens will not retract if removed while the camera is on. To retract the lens, turn the camera off , reat-
tach the lens, turn the camera on, and then turn the camera off and remove the lens in the correct order.
B
Attaching and Removing the Lens Hood
Attaching and Removing the Lens Hood
The lens hood screws directly onto the attach-
ment point for 46 mm fi lters.
• Before attaching or removing the lens hood,
turn the camera off and confi rm that the lens is
retracted. In addition, be careful not to touch or
apply excessive force to the glass part of the lens.
• To remove the hood, unscrew it from the lens.
Shooting Close-Ups
Shooting Close-Ups
This lens can be used for close-ups, letting you get closer to your subject so that it fi lls
more of the frame. When shooting close-ups, note the following:
• Close-ups are prone to blur caused by camera shake. We recommend that you mount
the camera on a tripod and release the shutter using an optional remote cord or wire-
less remote controller.
• Shooting at short focus distances noticeably reduces depth of fi eld. To increase depth
of fi eld and so increase the apparent depth of focus in front of and behind the focus
point, stop aperture down and increase exposure times.
• Be careful not to strike your subject when using the lens hood.
Adjusting Aperture
Adjusting Aperture
The aperture of the lens varies in a range that changes with focus distance. At a focus
distance of infi nity, aperture ranges from f/2.8 to f/22, while the range at a focus dis-
tance of 0.16 m (0.53 ft) is f/5.6 to f/32. At apertures matching or close to the maximum
and minimum for the lens in modes A and M, eff ective aperture 
justed for changes in focus distance as shown. 
2
For example, if an aperture of f/2.8 is
selected at a focus distance of infi nity, the eff ective aperture when the focus distance is
reduced to 0.16 m (0.53 ft) will be f/5.6.

image sensor varies with focus distance. The image darkens as the focus distance
drops and the reproduction ratio increases. The camera consequently shows an "ef-

Choosing a Reproduction Ratio
Choosing a Reproduction Ratio
To take pictures at a selected reproduction ratio—for example, 1:1 (life size) or 1:2 (half
life-size):
z
Slide the focus-mode switch to M.
x
Rotate the control ring until the desired reproduction ratio is selected on the
reproduction ratio indicator.
• For example, to select a reproduction ratio
of 1:2, rotate the control ring until the in-
dex points to "1:2". Do not rotate the con-
trol ring after choosing the reproduction
ratio.
c
Position the camera so that the subject is in focus.
• Move the camera forward or back until the image in the shooting display is in
focus.
A
Reproduction Ratio
The "reproduction ratio" is the ratio of the apparent size of an object on the image sensor to its true size. If the length
of the subject on the image sensor is 1 cm when the actual subject is 2 cm long, for example, the reproduction ratio
is 1:2 (half life-size).

tion. Normal function can be restored by pressing the
shutter-release button.
• The focus position may change if you turn the camera off and then on again after
focusing. If you have focused on a pre-selected location while waiting for your sub-
ject to appear, we recommend that you do not turn the camera off until the picture
is taken.
Cameras with AF-Assist Illuminators
Cameras with AF-Assist Illuminators
The lens or lens hood may block the light from the camera AF-assist illuminator.

Using the Lens on Cameras with a Built-in Flash
Using the Lens on Cameras with a Built-in Flash
Shadows will be visible in photos where light from the built-in fl ash is obscured by the
lens or lens hood. Remove the lens hood before shooting. Note, however, that depend-
ing on the distance to the subject, and in the case of zoom lenses also on the lens focal
length, shadows may appear even when the lens hood is removed.
• For the information on focal lengths and subject distances at which shadows will not
appear in photos taken with a built-in fl ash, visit the site below.

Precautions for Use
Precautions for Use
• Do not pick up or hold the lens or camera using only the lens caps or lens hood.
• Keep the CPU contacts clean.
• Should the rubber lens-mount gasket be damaged, cease use immediately and take
the lens to a Nikon-authorized service center for repair.
• Replace the lens caps when the lens is not in use.
• Do not leave the lens in humid locations or in locations in which it may be exposed to
moisture. Rusting of the internal mechanism can cause irreparable damage.
• Do not leave the lens next to open fl ames or in other extremely hot locations. Ex-
treme heat could damage or warp the reinforced plastic exterior.
• Taking the lens from a warm to a cold environment or vice versa may cause damaging
condensation inside and outside the lens. Place the lens in a sealed bag or plastic case
before taking it across a temperature boundary. The lens can be taken from the bag or
case once it has had time to adjust to the new temperature.
• We recommend that you place the lens in its case to protect it from scratches during
transport.
Lens Care
Lens Care
• Removing dust is normally suffi cient to clean the glass surfaces of the lens.
• When cleaning the fl uorine-coated front lens element:
- Remove fi ngerprints and other oily stains with a soft, clean cotton cloth or third-
party lens cleaning tissue; clean from the center outwards using a circular motion.
- To remove stubborn stains, wipe gently using a soft cloth lightly dampened with a
small amount of distilled water, ethanol, or third-party lens cleaner.
- Drop-shaped marks may form on fl uorine-coated surfaces, which are highly water-
and oil-repellent. Such marks can be removed with a dry cloth.
• When cleaning the rear lens element, which is not fl uorine-coated:
- Remove fi ngerprints and other oily stains with a soft, clean cloth or third-party lens
cleaning tissue lightly dampened with a small amount of ethanol or third-party lens
cleaner; clean from the center outwards using a circular motion. Be sure to clean
evenly and thoroughly without leaving smears.
• Never use organic solvents such as paint thinner or benzene to clean the lens.
• Neutral Color (NC) fi lters (available separately) and the like can be used to protect the
front lens element.
• Do not store with naphtha or camphor moth balls or in direct sunlight. If the lens will not
be used for an extended period, store it in a cool, dry location to prevent mold and rust.

• Remove dust with a soft brush.
• Water and stains can be removed from the surface with a soft, dry cloth. Do not use alcohol, benzene, thinner,
or other volatile chemicals.
• Do not store in locations exposed to direct sunlight or high temperatures or humidity.
• Do not use the case to clean the monitor or lens elements.
• Be careful that the lens does not fall from the case during transport.
