S-Series Lighting Heads

Interfit Photographic’s S1 is a 500w/s strobe with a built-in battery that supports high-speed sync and TTL for Canon, Sony and Nikon cameras. The S1’s interchangeable lithium ion battery is good for up to 350 full-power flashes in either manual or TTL modes and up to 400 full-power flashes when shooting in HSS mode. Unlike many rival battery-powered strobes, the S1 can also run on AC power thanks to the included multi-voltage AC adapter. The flash works with an optional remote for Canon and Nikon cameras to enable TTL metering. Recent firmware updates have given the S1 greater power control with a newly expanded nine-stop adjustment range, up from the original seven.
