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 to protect the lens against
damage. Nikon lens hoods come in four types, depend­
ing on the lens: screw-in, snap-on, slip-in and 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 snap-on hood
can be reversed for storage on the lens, and the lens and
its hood can be stored together in the ever-ready 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 filter requires exposure
compensation when used with the Nikon F2SB Photo-
mic. When using the R60 filter under tungsten light,
increase the exposure by one f-stop more than indicated
by the exposure meter.
Note: If you wish to leave a filter on the lens to protect the lens
against accidental damage, the use of the L37 or L37C filter is
recommended.
