The Sto-fen SS-285 is a sensor shield for the Vivitar 285. This shield prevents the flash sensor from detecting bounced light or the light output from other flashes, which could confuse the sensor to cut off the flash prematurely. With the shield in place, only the light reflecting off the subject will affect the output of the flash.
