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.
