The Lux Junior Retro Flash from Godox, compatible with cameras from Fujifilm, Canon, Nikon, Olympus, and Sony, is a tiny light source with basic functions and small enough to be regularly mounted on your camera.

Features:

• Power, ISO, aperture, distance settings
• Guide number: 12 (ISO 100)
• 7 output levels: 1/1 to 1/64
• Operates on 2 x AAA batteries
• Manual and automatic modes
• Fixed 28 mm coverage area

The device, referred to as a "Retro" flash, 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 on separately available AAA batteries and comes with a trigger cable and a storage pouch.
