The DF-583 Power Zoom Speedlight for Canon from Vivitar is a fully automatic, dedicated Canon system speedlight. It features full through the lens (TTL) support for Canon DSLR cameras, and a bounce, zoom, and swivel head that gives you more creativity when lighting your photos. Eight selectable power levels and an automatic shutter speed grant you precise control over the ten power zoom positions from 18mm-180mm, and high speed synchronization - to capture fast subjects.
Versatile enough to be used outdoors, as well as inside a professional studio setting, the DF-583 makes it possible to set up a studio environment anywhere, anytime. It incorporates a built-in reflecting plate and diffuser, which expands the angle of illumination for larger venues. A red focus beam will help you achieve focus in low light conditions, and power saving circuitry incorporates an auto-off element to give you longer battery life.
The built-in rotary dial makes selecting modes and settings quick and easy, while the information displayed on the rear LCD panel clearly shows those settings you've chosen. Power the flash with any four AA batteries, and turn on the power saving function in order to conserve battery power and prolong battery life. With all of these features, and more, the Vivitar DF-583 helps photographers fill shadows, add depth, avoid red-eye, and improve image resolution - with detailed manual controls when you want them or simple automatic modes when you don't.
