FIL TERS Nikkor lenses and Nikon filters are compatible
with each other, Therefore, for best results,
use
Nikon filters, which are made
of
optical
glass,
ground and polished
so
that both surfaces are
optically flat and parallel. They are available
in
both screw-in and series mounts, depending
on
the
lens
.
No
exposure compensation for filters
is
necessary
with the Nikomat
ELW,
except the
R-60,
which
is
us
ed for infrared photography. The built-in
ex-
posure met
er
reads only the light passing through
the
lens
and
therefore compensates for the
loss
of
light.
If you want to
use
a filter to protect the front
of
your le
ns
without any overt effect
on
your
pic-
tures,
us
e the L
-3
7
UV
haze filter.
