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.
