Nauticam NA-A1II Housing for Sony α1II / A9III

The NA-α1II is part of Nauticam’s premium housing line, combining exceptional durability with a layout optimized for demanding underwater photographers and filmmakers. Based on the NA-α9III architecture, it supports both the Sony α1 II and α9 III bodies without internal adjustments, making it a versatile platform for high-performance imaging.

Its marine-grade anodized aluminum build ensures excellent corrosion resistance and long-term reliability. The ergonomic design places all essential controls within easy reach, including dedicated levers for AF-ON, REC, PLAYBACK, and conveniently positioned dials, allowing intuitive operation even with gloves.

The housing features Nauticam’s integrated vacuum monitoring and leak detection system, which continuously checks the internal seal and alerts the user in case of pressure loss.
