Nissin Di28 is a compact professional flash developed for digital SLR cameras with the latest TTL flash control technology. It is compatible with Canon EOS and Nikon digital SLR cameras and supports E-TTL II, E-TTL, and i-TTL auto-flash systems. The flash exposure compensation feature allows users to control the intensity of the flash, while the built-in light diffuser softens the light for more natural-looking portraits. Additionally, the Flash Power Lock System ensures accurate exposure for the main subject, even in challenging lighting conditions.
