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.
