The NA-Z7II underwater housing follows suit with Nauticam's drive for innovation. Both the Nikon Z 6II and Z 7II present shooters with the ability to use both the available legacy F Mount lenses via the FTZ adapter in addition to their native Z Mount optics. To support both the legacy and native lenses, Nauticam has integrated the NA-Z7II into the N120 port system. This is critical as the new Z mount lenses are being phased in over the next few years. 

The Nauticam NA-Z7II housing features two lens release buttons that correspond to either F or Z mount lenses. When switching between F and Z mount lenses, the camera must be removed from the housing to remove the adapter. When working within either the F or Z mount system use the appropriate lens release button to switch lenses without having to remove the camera from the housing. A vacuum system reset switch is located below the tray as well so there is no need to open the rear of the housing during lens or port changes.

The NA-Z7II is part of the N120 port system which allows for full support of Nikon F mount lenses with the same ports needed for their application on Nikon SLR housings. As more Z mount lenses become available Nauticam will add supported configurations.

Nauticam engineers are obsessed with functionality and this is evident in the location of essential controls. Regardless of where the control is located on the camera, the Nauticam housing puts them where you need them to be underwater. For those switching between photo and video modes, an easily reachable switch is located on the right rear of the housing. The right side double thumb lever, easily reached from the right handle features access to the AF-on and Record buttons respectively. Between the double thumb lever and the multi-stage shutter release is an ISO lever allowing quick changes to sensitivity.

The left double thumb lever accesses the DISP and Playback controls. The Zoom In and Zoom Out controls, located on the right rear of the camera body is relocated to the left side of the housing to a location more familiar to Nauticam housing users.

The switch that allows for switching between the LCD display and the EVF, a crucial and much used control with mirrorless systems is located close to the left handle within easy reach.

Front and rear control dials are readily accessible by the familiar large knurled dials at the right handle. The ergonomic housing handles are rubberized and feature stainless steel stiffening brackets to ensure a stable platform when using large strobes or video lights attached to the pre-installed 1" mounting balls.

The NA-Z7II comes with Nauticam's self powered manual flash trigger preinstalled. The flash trigger plugs into the hot-shoe of the camera and uses LED lights recessed into each of the two optical bulkheads to trigger supported underwater flashes when used with the correct fiber optic connection. The flash trigger is powered by coin cell batteries that provide thousands of flashes per battery. The flash trigger can be upgraded to support TTL triggering (PN 26308 TTL Converter for Nikon).

The Nauticam vacuum check and leak detection system is shipped with NA-Z7II as standard equipment. Combined with an accessory M16 vacuum valve (PN 25625), 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.

Optical performance is just as necessary as camera performance and this becomes even more critical given the challenges of filming underwater. The Nauticam NA-Z7II uses the same N120 Port System as the previous NA-Z7 which makes for a seamless transition for those upgrading to the "II." While this system provides exceptional optical-glass and flat port solutions for a wide variety of F and Z Mount lenses, the real power of the Z 6II and Z 7II can be realized using Nauticam's Water Contact Optics. This lineup of dry and wet lenses are conceived using commercial lens-design software to achieve truly unparalleled underwater image quality both for stills and video in both macro and wide-angle situations.

The WACP-1 and WACP-2 achieve ultra-wide 130º fields-of-view with reduced distortion over conventional optics while featuring ~0" minimum focus distances, zoom through capabilities and unbeatable corner sharpness at even wide-open apertures such as F5.6. The SMC-1 and SMC-2 macro wet-optics, when used with the Nikon 105mm f/2.8G VR macro lens provide 2x and 4x magnification respectively and the SMC-1 actually provides a resulting image with increased contrast and sharpness than the 105mm lens itself can achieve in air without a magnifier.

The NA-Z7II features the larger-bore M28 bulkhead opening that allows for the use of Nauticam HDMI 2.0 cables for connection to recorders such as the Atomos Ninja V.

Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.

The NA-Z7II supports the FTZ adapter and belongs to the N120 Port System meaning Nikon F Mount lenses can be used with the same ports and extensions as on a Nauticam Nikon DSLR Housing. As more Z mount lenses become available, supported lenses will be integrated into the port system.

Stiffening handle brackets are included with the housing. These brackets eliminate any flex or wobble when using big strobes, and provide multiple attachment points for lanyards or other accessories.
