THE NAUTICAM NA-A7IV UNDERWATER HOUSING
The NA-A7IV is designed as an optimized solution for both underwater still and moving image capture.
Outfitted with Nauticam's extensive lineup of accessories, the NA-A7IV can be customized to excel in either role.
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.
MISSION CONTROL
Never miss a shot looking for a button or dial. 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 dual thumb lever near the right handle actuates the REC and AF-ON buttons and a single lever near the left handle is for PLAYBACK.
HDMI 2.0
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 allowing for recording in edit-friendly codecs such as ProRes. See the resources sidebar for additional details and recommended setups.
PREMIUM PROFESSIONAL OPTICS
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 CHECK AND LEAK DETECTION
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.
Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.
SUPPORT & DOWNLOADS
STROBE TRIGGERING
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).
