Stainless Steel Handle Brackets

The steel brackets included with the housing provides stability and eliminates the flex and wobble when using big strobes or video lights. It also serves as attachment points for accessories such as lanyards.

Compatible Premium Optics

The housing has been designed around the N100 Port System which supports various optics. When using an E-Mount to EF-mount lens adapter and an N100 to N120 adapter more lenses and ports are compatible with the housing. Wet lenses such as WACP, WACP-1 or WWL-1B for wide angle and SMC-1 or SMC-2 for macro/super-macro are also supported.

Viewfinder Options for Enhanced Composition

Nauticam offers two high-quality viewfinder options for the NA-A9III housing: the 180º straight enlarging viewfinder and the 45º angled enlarging viewfinder. Both options are designed to improve the ease of close-quarters work, particularly for macro photography. The straight viewfinder provides a wide, magnified view, while the angled version makes it easier to shoot at lower angles. Both viewfinders feature exceptional optics and allow for bright, clear viewing of the entire image. The external dioptric adjustment allows for quick personal adjustment, ensuring optimal viewing without the need for tools.

Flash Triggering for Reliable Lighting Control

The Nauticam housing for Sony A1 II / A9 III features a built-in flash triggering system that allows your camera to output a flash signal to compatible external strobes. Whether you’re shooting with manual flash or TTL, the NA-A9III housing ensures precise and reliable flash control, providing the perfect lighting for your underwater subjects.

Integrated Vacuum Check and Leak Detection System

The vacuum check and leak detection system is included as standard with the Nauticam Sony A1 II / A9 III housing, ensuring that the housing remains watertight during your dives. The system continuously monitors the integrity of the housing seal, providing real-time updates via a color-coded LED light system. If there’s any indication of a loss of vacuum or water intrusion, the system will trigger both a visual and audible alarm, giving you peace of mind while diving.

This leak detection system is temperature-compensated, which helps eliminate false alarms that could be triggered by external temperature changes or heat buildup from your camera during extended video recording. The built-in system allows for continuous monitoring of the housing’s status, ensuring that you’re always aware of its condition while underwater.
