AOI Q1 RC Ultra Compact Underwater Strobe

The AOI UCS-Q1RC is a compact, high-performance underwater strobe designed for advanced underwater photographers who require reliable lighting with Olympus RC (Remote Control) compatibility. Working similarly to TTL, the RC system allows the camera to automatically control strobe output, enabling accurate exposure without manual flash adjustment—especially useful for Olympus OM-D and TOUGH camera systems.

Built from durable polycarbonate and glass fiber, the Q1RC delivers dependable performance at depths of up to 60 meters. It combines powerful illumination, fast recycle time, and flexible exposure control in a lightweight, travel-ready housing designed for demanding underwater environments.

With a guide number of 22, wide 85° beam coverage (with diffuser), and fast 0.85-second recycle time, the Q1RC ensures consistent lighting for both macro and wide-angle underwater photography. It supports RC flash, TTL auto, manual, and FP (high-speed sync) modes depending on compatible camera systems.
