Power, ISO, aperture, distance settings

Referred to as a "Retro" flash, the device features a simple adjustment dial that links ISO values with aperture values, power levels, and shooting distances.

Control functions include an optical mode with settings S1 and S2. In S1, the flash is triggered in response to another manual or TTL flash, while in S2, the Retro Flash responds similarly but ignores the first flash.

The device operates with separately available AAA batteries and comes with a trigger cable and a storage bag.
