Description

The Nikon Speedlight SB-23 is a classic, manual-only external flash unit that was designed for Nikon film SLR cameras. It delivers a guide number of approximately 23 meters (75 feet) at ISO 100, making it suitable for both fill flash and primary flash applications under a variety of lighting conditions. The SB-23 offers full manual control over flash output, allowing photographers to dial in the exact amount of light needed by selecting power ratios (e.g., 1/1, 1/2, 1/4, etc.).

One of its key features is the tilt and swivel flash head, which enables bounce flash techniques. This helps create softer, more natural lighting by directing light off a ceiling or wall, rather than producing harsh, direct illumination. Despite its simplicity compared to modern TTL-equipped speedlights, the SB-23 remains valued for its reliability, ease of use, and straightforward design—ideal for photographers who prefer manual control over their flash lighting.

Powered by four AA batteries, this compact flash unit is both portable and easy to deploy, making it a practical choice for photographers using Nikon film cameras who need dependable lighting in a variety of shooting scenarios.
