Vivitar 273 Auto Thyristor (Pre-owned)
Condition: Good condition, has some wear from previous owner but works well
The Vivitar 273 Auto Thyristor is a classic automatic electronic flash that became a favorite among film photographers for its reliability, simplicity, and surprisingly sophisticated automatic exposure capabilities. Utilizing an onboard thyristor sensor, the flash automatically measures reflected light and cuts off output when proper exposure is reached, providing accurate flash exposures without requiring TTL communication with the camera. Compatible with virtually any camera equipped with a hot shoe or PC sync connection, the Vivitar 273 remains a popular choice for vintage camera enthusiasts and collectors alike.
Function: Provides automatic or manual flash illumination for film cameras using a built-in light sensor that adjusts flash output for proper exposure.
