‹ BackDescription
AOI UCS-Q1 Ultra Compact Strobe – 2027 Edition
The AOI UCS-Q1 Ultra Compact Strobe 2027 Edition is a compact and powerful underwater strobe designed for beginners, ambitious underwater photographers and anyone looking for a lightweight, easy-to-use lighting system. With guide number 22, an integrated LED focus light and automatic flash emulation, the Q1 is ideal for macro, close-up and wide-angle underwater photography.
Automatic Exposure by Emulating the Camera Flash
The major advantage of the new 2027 Edition is that the AOI UCS-Q1 can be used with virtually any camera equipped with its own built-in or onboard flash. Via the optical fibre cable, the Q1 detects and emulates the camera flash behaviour. This allows the strobe output to be automatically adjusted, resulting in clean, reliable and well-exposed images without the need for constant manual correction.
This makes the AOI UCS-Q1 especially attractive for compact mirrorless cameras, entry-level systems and underwater photographers who want simple but effective flash control.
