The AF35 sensor is positioned to provide the most reliable strobe triggering possible without exposed cables which require maintenance and can tangle or break. Two large, easy to read dials provide all of the settings necessary for control of the flash system. The AF35 strobe rear dial features OFF, Auto (TTL) plus six Manual Power settings. The AF35 sensor rear dial provides simple plus/minus EV exposure compensation in the Auto (TTL) mode. The system's comfortable rubberized grip and neutral buoyancy make it a pleasurable addition to any housing. A flexible arm system allows quick repositioning of the strobe angle and adds no weight to the system. A simple battery door is easy to remove and replace and provides a clear view of the o-ring seal. The strobe's battery compartment is independently sealed from the electronics preventing further damage in the event of a flood. This kit includes everything you need to add a strobe to almost any Ikelite compact digital housing, plus other housings featuring 1/4-20 mounting like Canon, Olympus, Sony and more!
