The Backscatter Atom Flash AF‑1 delivers serious power in a compact, travel-ready package—perfect for underwater photographers who don’t want to compromise. With an underwater guide number of ƒ28, it’s capable of illuminating everything from expansive wide-angle scenes to tight macro subjects. The 110° beam provides smooth, even light across your frame, and its included flat diffuser (plus optional dome diffuser) further broadens and softens the output. Built-in 1,000-lumen white and red focus lights make aiming precise, especially for macro or shy subjects when paired with the Optical Snoot OS‑2.
It supports a full range of flash modes: Smart Control TTL (for Sony, Olympus & OM System), Manual with 11 power levels, RC wireless triggering, and High-Speed Sync (HSS). A user-friendly, auto-rotating LCD displays power, shots remaining, and battery life. The AF‑1 recycles in under a second at full power and delivers over 600 flashes per charge, thanks to its twin 18650 batteries. All of this comes in a rugged, low-profile body that’s easy to pack and travel with — yet tough enough to thrive on shore dives or remote destinations.
