TIPS ON CLOSE-UP PHOTOGRAPHY LENS CARE

• When using the optional Extension Ring

PK-13, Bellows Focusing Attachment PB-6,

or other Nikon equipment to obtain a repro-

duction ratio of more than 1:2, better opti-

cal performance will be obtained by stopping

down the lens to f/4 or a smaller aperture

setting.

• Always keep the lens surfaces clean, as dust

or smudges can interfere with image sharp-

ness. Use a blower brush to remove dust,

never

cloth

or facial tissue. Stubborn

smudges should be removed with photo-

graphic lens tissue moistened with lens

cleaner or pure ethyl alcohol. Wipe the lens

using a circular motion starting at the center

and moving slowly to the outside. Ether

should not be used, as it may cause hard-to-

remove streaks especially on multicoated

lenses.

• To protect the lens surface from dirt or dam-

age, the use of an L37C filter is recommended

at all times. The lens hood also helps to pro-

tect the lens.

• Keep the lens cap in place whenever the lens

is not in use.

• Attach both the front and rear caps when

the lens is stored separately.

• To ensure proper fit of the lens when stored

in the leather lens case, set the lens' focusing

ring to the infinity (°°) setting.
