Filters
• Nikon filters can be divided into three types: screw-in, drop-in,
and rear-interchange. With the exception of the R60, exposure
compensation need not be adjusted when a Nikon filter is at-
tached (in the case of the R60, set exposure compensation to +1).
Filters manufactured by other makers may interfere with autofo-
cus or electronic range finding.
• The D100 can not be used with linear polarizing filters. Use the
C-PL circular polarizing filter instead.
• The NC and L37C filters are recommended for protecting the lens.
• To prevent moiré, use of a filter is not recommended when the
subject is framed against a bright light, or when a bright light
source is in the frame.

Speedlights
■ Nikon SB-80DX Speedlight
This high-performance Speedlight has a Guide Number of 53/174
(m/ft, manual mode, 35-mm zoom-head position, ISO 200, 20
°
C/
68
°
F; GN at ISO 100 is 38/125) and accepts four LR6 (AA) alka-
line batteries or SD-7, SD-8A, and SK-6 power sources (all avail-
able separately). For bounce-flash or close-up photography, the
flash head can be rotated through 90
°
up, 7
°
down, 180
°
left,
and 90
°
right. Light from the flash can be diffused for wide-
angle photography by using the SB-80DX in combination with a
wide panel or bounce adapter, producing soft lighting that bal-
ances the foreground subject with the background in close-ups
and bounce-flash photography. The SB-80DX is equipped with
an illuminator to assist in adjusting settings in the dark. Custom
settings allow you to fine-tune all aspects of flash operation.
■ Nikon SB-50DX Speedlight
This Guide Number 32/105 Speedlight (m/ft, manual mode, 35-
mm zoom-head position, ISO 200, 20
°
C/68
°
F; GN at ISO 100 is
22/72) is powered by two CR123A (DL123A) three-volt lithium
batteries. In addition to auto power zoom, it has a tilt position of
+90
°
to –18
°
, allowing it to be used both for bounce-flash pho-
tography and at ranges as close as 30 cm (1´). The following sync
modes are supported: slow sync, rear-curtain sync, and manual.
If the built-in Speedlight is raised when the SB-50DX is set to man-
ual in the bounce-flash position, both Speedlights will fire.
