StandardDescription
The Vivitar 2800 is a sophisticated "Auto Thyristor" flash unit that represented a significant step up from basic manual strobes. The "Thyristor" technology was a major innovation; it allowed the flash to quench its own light output once the correct exposure was reached, saving unused energy and drastically shortening recycle times between shots. It features a tilting head for "bounce flash" photography—allowing the user to aim the light at a ceiling (45°, 60°, 75°, or 90°) to create softer, more natural lighting. The rear control panel includes a multi-colored exposure guide and an "Auto Check" light that confirms if enough light was produced for a successful exposure. This unit was a highly popular choice for enthusiasts using cameras like the Pentax K1000 or Minolta SRT series, providing advanced lighting control in a compact, battery-efficient package.Category
