ACCESSORIES
Lens Hoods
The
use
of
a lens
hood
is
recommended
at all times
to
prevent
extraneous
light
from
striking
the
lens surface
and causing flare
or
ghost,
and
as
an
added
measure
of
protection
against damage
to
the
lens.
Nikon
lens
hoods
come
in four
types,
depending
on
the
lens:
Screw-In, Snap-On, Slip-On arid Built-In.
They
are
calculated precisely for each focal-length
Nikkor
lens
to
provide
maximum
protection
against
stray
light.
To
attach
or
remove the snap-on
hood,
first depress
the spring
latch
- which
is
marked
with
an
arrow
-
and
slide it in the
direction
of
the
arrow.
The
hood
will
also fit
directly
over a screw-in filter, so
both
can be
used
on
a lens
at
the same
time
. When
not
in use, the
28
snap-on
hood
can be reversed for storage
on
the
lens,
and
the
lens
and
its
hood
can
be
stored
together
in
th_e eveready case.
Filters
Nikon filters are made
of
optical
glass,
ground
and
polished so
that
both
surfaces are
optically
flat
and
parallel.
Nikkor
lenses
and
Nikon filters are made for each
other.
For
best results, use
Nikon
filters
on
Nikkor
lenses. The filters are available in
both
screw-in
and
series
mounts,
depending
on
the
lens.
Except
for the
R60,
no
Nikon
ftlter requires
exposure
compensation
when
used
with
the
Nikkormat
FT3.
