AOI ACT-AD-A5 Adapter
The AOI ACT-AD-A5 Adapter is a precision-engineered mounting bracket designed exclusively for the DJI Osmo Action 5 and Action 4 series. Because this adapter is a critical component of the AOI UH-ACT Universal Housing ecosystem, it allows you to bring your DJI camera into a professional underwater filming setup. Furthermore, it ensures the camera is perfectly centered to eliminate vignetting when used with AOI’s high-performance wet lenses.

Precision Fit & Stability
Crafted from high-grade, marine-stable polycarbonate, the AOI ACT-AD-A5 Adapter offers a lightweight yet incredibly rigid solution for underwater videography. Additionally, the design specifically matches the form factor of the Osmo Action 5, providing a secure fit that prevents any internal movement. Specifically, this stability is crucial when capturing high–resolution 4K or 120fps footage in surge-heavy environments.
Seamless Workflow & Integration
The installation of the AOI ACT-AD-A5 Adapter is quick and intuitive, which is ideal for divers who need to change batteries or memory cards between boat dives. Moreover, by using this dedicated adapter, you gain full access to the AOI Quick Release System for rapid lens swaps underwater. Consequently, you can transition from wide-angle landscapes to close-up macro shots in seconds. Similarly, its durable construction ensures a long lifespan even with frequent exposure to tropical saltwater.
