This feature enables photographers to focus on their composition without worrying about manual exposure settings.

The build quality of the SB-21 is another highlight, as it is designed to withstand the rigors of regular use. It features a durable exterior that enhances its longevity, making it a trustworthy tool for outdoor and event photography. Additionally, the flash unit supports wireless operation, enabling users to trigger it remotely for creative lighting setups.

The Nikon SB-21 also includes a variety of accessories, such as diffusion panels and bounce cards, allowing further customization of light output to achieve specific effects.

Overall, the Nikon SB-21 stands out as a reliable and feature-rich external flash unit that meets the demands of various photographic styles.
