Nikon SB-28DX Speedlight
This Speedlight has a guide number of 50 (manual mode, 35-mm zoom-head posi- tion, ISO 200 m, 20 °C/68 °F) and is powered with four alkaline batteries (other power sources for the SB-28DX include the SD-6, SD-7, SD-8A, and SK-6 power bracket—all available separately). When attached to cameras in the D1 series, it supports D-3D multi-sensor balanced fill-flash for natural, balanced light, even when the scene contains highly reflective objects or the background is very far from the camera. The SB-28DX is equipped with an AF-Assist Illuminator, allowing autofocus to be used when shooting very dark subjects. It also boasts auto power zoom that changes the flash angle according to the focal length of the lens, and supports Slow Sync, Rear-Curtain Sync, non-TTL auto, Manual, Repeating, and FP High-Speed Sync flash modes.
