The Bower SFD328 Digital Slave Flash is compatible with all digital cameras, with or without built-in flash capability. It has a guide number of 92' at ISO 100 and 50mm and it works as a slave flash where it can be set for a single flash camera or a pre-flash camera. It also has a hot shoe so that it can be fired from the camera directly, and the flash is fully synchronized with fill-in flash and red-eye reduction flash and can be used with virtually all of the digital cameras on the market.
Compact and lightweight, the flash still provides some extra features like bounce & swivel, and a manual zoom head of 28-85mm.
Flawless Sync with Preflash Systems
Evaluative preflash systems are complex and many independent devices aim to work with them, but the SFD328 is compatible with both pop-up and shoe-mounted flashes for the Canon, Nikon, Olympus, Pentax, and Sony systems.
Bounce & Swivel Head
Flash has vertical bounce of 90° and horizontal swivel of 330°
