Technical Notes—Optional Accessories
Optional Flash Units (Speedlights)
When used with a compatible Speedlight such as the SB-800 or SB-600
(available separately), the D50 supports the Nikon Creative Lighting System
(CLS), including i-TTL fl ash control (
127), Flash Color Information Com-
munication, and FV lock ( 98). The built-in fl ash does not fi re when an
optional fl ash unit is used.
SB-800 and SB-600 Speedlights
These high performance Speedlights have Guide Numbers of 53/174 and
42/138 respectively (m/ft, 35-mm zoom head position, ISO 200, 20 °C/
68 °F; GNs at ISO 100 are 38/125 and 30/98 respectively). The fl ash head
can be rotated through 90 ° above the horizontal, 180 ° left, and 90 ° right
for bounce-fl ash or close-up photography. The SB-800 can be rotated 7 °
below the horizontal. Auto power zoom (24–105 mm and 24–85 mm, re-
spectively) ensures that the illuminating angle is adjusted in accord with lens
focal length. The built-in wide panel can be used for an angle of 14 mm
(the SB-800 also supports 17 mm). An illuminator is included to assist in
adjusting settings in the dark.
