Light Your Shots from Every Angle
Meet the Vivitar SF-4000 — a dual-purpose flash built for photographers who demand flexibility without compromise. Whether you're shooting portraits in a studio or capturing candid moments on the go, this unit performs as a standalone bounce zoom flash or as a wireless slave trigger, giving you two powerful tools in one compact body.
At the heart of the SF-4000 is a multi-angle 3-position zoom head that adapts to wide angle, normal, and telephoto shooting distances, so your light coverage always matches your lens choice. The bounce head tilts up to 90°, letting you soften and redirect light off ceilings or walls for a more natural, flattering look.
Smart Slave Modes for Modern Cameras
Where the SF-4000 truly stands out is its four dedicated slave modes. These modes are engineered to sync with a wide range of cameras — including those that fire an immediate built-in flash, as well as models using single or multiple pre-flash red-eye reduction systems. That kind of broad compatibility means fewer frustrating misfires and more consistent results. Powered by 4 AA batteries, it's easy to keep this flash ready wherever your shoot takes you.
