Nikon Camera F3AF - Manual (Page 105)

ACCESSORIES —continued—
Filters
Constructed of Nikon's own optical glass, Nikon filters not only
protect the front of the lens, but provide color correction or
allow you to create special effects. As shown in the table, Nikon
filters are broadly divided into the screw-in type and the drop-
in type.
Notes:
1) For lens protection, the L39 and L37C are recommended.
2) When shooting a backlit subject or if there’s a bright source in the
frame, a ghost image is likely to result when using a filter. In this case,
you should take the picture without a filter.
3) The F3AF's autofocus/focus-aid function cannot be used with the R60.
4) In low-light situations, the use of an ND fitter may cause the focus-
impossible warning to blink.
Lens Hoods
Recommended to prevent extraneous light from striking the
lens, Nikon's lens hoods come in four styles: screw-in, slip-on,
snap-on, and collapsible rubber. Every lens should be fitted with
the lens hood specially designed for it. Note, however, that some
lens hoods can be used in common by several lenses.
