The Lux Senior Retro Camera Flash by Godox is a compact light source measuring 7 x 4.5 x 3.3 inches, designed to be compatible with FUJIFILM, Canon, Nikon, Olympus, and Sony cameras. This "retro" flash features a straightforward dial that aligns ISO settings with aperture values, power levels, and shooting distances. For instance, when shooting at a distance of 5 feet with an ISO of 400, the dial indicates f/5.6 and 1/16 power. Additionally, the flash includes an Auto Mode that defaults to f/2.8 at ISO 100. Control options encompass an Optical Mode with S1 and S2 settings; in S1, the flash activates in response to another manual or TTL flash, while in S2, it will respond but disregard the initial flash. The device operates on a rechargeable battery and is supplied with a triggering cable and a storage bag.
