AOI UIS-P1 Ultra InTeLi Underwater Flash

Amazing Intelligence in the New AOI UIS-P1 Flash

The AOI UIS-P1 Ultra InTeLi is the latest flash to be added to the AOI product range. It is probably the most technologically advanced underwater flash currently on the market in this category. It offers both Sony TTL and OM system RC compatibility.     

The new AOI UIS-P1 leverages a beloved feature of the UCS-Q1RC: the AOI InTeLi™

mode. Widely recognized as one of the most consistent and accurate TTL modes in the underwater strobe market, it revolutionized underwater macro photography. Its standout feature, the Intelligent Macro (i-Macro™) function, offers precise exposure for macro shots and has become a game-changer, particularly when paired with the best-selling OM System Tough TG series.

What is the AOI InTeLi™ Mode?

The AOI InTeLi™ Mode represents the next generation of TTL flash compatibility, optimized specifically for underwater use. Calibrated to manufacturer’s specifications, it ensures consistently accurate exposures, surpassing previous generation of TTL. Underwater macro photography is further enhanced by i-Macro™, which was initially available for OM System cameras. Now, the AOI InTeLi™ Mode also supports Sony cameras, offering Sony TTL, i-Macro, TTL HSS, and M HSS functionalities.

Bridging Technology and Creativity

Contrary to popular belief, research shows that underwater photographers readily embrace technological advancements to enhance their art. With the UIS-P1, AOI integrates the full suite of AOI InTeLi™ features, a bright ring-shaped flash tube, an intuitive user interface, and innovative functions. One new feature specifically benefiting wideangle fans is the “out of range” warning when in TTL mode.

Keeping in mind that underwater photographers are multidimensional, AOI has designed three additional product add-ons that will allow the strobe to be more utilitarian:

1. Diffuser – Softens light output and evens out light coverage (Offered as standard accessory).

2. Reflector Ring – Reduced beam angle and improves light output by +1 F-stop (Offered as optional accessory).

3. Reducer Ring – Narrows beam angle, limit light leaks, and reduces backscatter (Offered as optional accessory).
