Foreword Tips on Using the Speedlight
•Thank you for purchasing the Nikon Speedlight SB-50DX.
Get to know your SB-50DX, and be sure to read this manual thoroughly
before using it.
Main features of the SB-50DX:
• The SB-50DX is a high-performance Speedlight having a guide
number of 22/72 (at 35mm zoom-head position, ISO 100, m/ft.,
20°C/68°F). According to the camera/lens used with the SB-50DX,
you can perform various types of TTL auto flash (p. 25) and Manual
flash (p. 31). When used with Nikon digital SLR cameras, D-TTL
auto flash can be performed.
• Automatic power zoom continuously changes the zoom-head
position from 24mm to 50mm according to the lens' focal length
(incompatible with some lenses, see p. 16). The built-in wide-flash
adapter increases the angle of coverage to match a 14mm lens
(p. 17).
• Flash head tilts up to 90° or down to –18°, enabling bounce-flash
photography (p. 40) or close-up photography (p. 43).
• When used with a camera having a built-in Speedlight, both the
SB-50DX and the camera’s built-in Speedlight fire simultaneously
(p. 42, 54) for double-flash photography. A diffuser (p. 42) is provided
to diffuse light for bounce-flash photography with the double flash.
• Wireless multiple flash photography (p. 48) is also possible.
• The supplied Infrared Filter SW-9IR enables you to use the SB-50DX
as an infrared remote commander (p. 53).
• For operation in dim light, an illuminator for the LCD panel is
provided (p. 8) and light condensing paint is applied to characters
and symbols on the backside (p. 7).

•Have Nikon spot-check your Speedlight regularly
Nikon recommends that you have your Speedlight serviced by an

•Using your Speedlight correctly
The Nikon Speedlight SB-50DX’s performance has been optimized for
use with Nikon brand cameras/accessories (including lenses).
Cameras/accessories made by other manufacturers may not meet
Nikon’s criteria for specifications, and nonconforming cameras/
accessories could damage the SB-50DX’s components. Nikon cannot
guarantee the SB-50DX’s performance when it is used with non-Nikon
brand products.
