The Housing
The latest in a long lineup of Sony mirrorless system housings, the NA-A7IV features the same intuitively placed controls, easy setup, and rugged reliability user's have come to expect. 
Regardless of where the control may be found on the camera, Nauticam engineers have placed that control on the housing where it is needed most. Essential dials and buttons are within easy reach of the reinforced ergonomic handles. Atop the housing, a new dedicated lever allows quick switching between Still, Movie and S&Q (VFR Video) modes.

A large bore M24 bulkhead is located at the front of the housing for use with HDMI 2.0 or HDMI 1.4 (with a step-down adapter to M16) external monitors and recorders. An additional M10 threaded mounting position near the front center of the housing also makes using an external monitor even easier. The A7IV can output 4:2:2 10-bit 4K at up to 60fps to external recorders.

Ports and lenses
Built around the N100 Port System for Sony E-Mount, the NA-A7IV can support a wide variety of native lenses with a selection of Optical Glass and Acrylic ports. When used with an E-Mount to EF-mount lens adapter and an N100 to N120 adapter (see Resources sidebar for supported adapters), the NA-A7IV can be used with the Canon N120 EF-Mount port system, expanding the capabilities of the system even further. Going beyond conventional optics the NA-A7IV can leverage the unparalleled optical quality of Nauticam's Water Contact optics such as the WACP-1 which offers up to 130º field-of-view, full zoom through, an almost 0" minimum focus distance with supported lenses. For macro, the SMC-1 and SMC-2 deliver tack-sharp super-macro magnification levels up to 4x with the Sony 90mm macro lens.

Vacuum valve and leak alarm
The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system, requiring only the optional M14 Vacuum Valve (25624). This monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum.

Triggering of external strobes is accomplished via the integrated fiber-optic bulkheads when using the optional Mini Flash Trigger for Sony (26302). Electronic triggering is also via an optional Nikonos Bulkhead. Note that when using this with the Vacuum Valve will require the optional M14 Offset Connector with Vacuum Valve II (25026).
