The WWL-C provides a crispy 130-degree diagonal field of view with the lens at 16mm and allows for full zoom through to about 60 degrees at 45mm.
The CMC-1 offers more magnification but is a bit more challenging. CMC-2 still offers a hefty 0.6X magnification but is a bit more forgiving.
The Z50 II is Nikon's follow-up to its inaugural DX (APS-C) sensor mirrorless camera that shares the new Z Lens Mount with its full-frame Z cameras. The Z50 II features several notable improvements over its predecessor, especially in video capture and autofocus. The Nauticam NA-Z50II is designed to be used exclusively with the Nikkor Z DX 16-50mm lens.
Nikon's Z Mount is one of the widest lens mounts in its class and enables faster, more compact lens designs. The Z50 II is equipped with the same 20.9MP DX (APS-C) CMOS image sensor as the Z50 but is mated to their newest EXPEED 7 processor. The Z 50 II lists a native ISO range of 100-51,200 and has extensive Auto ISO controls spread across its operating modes. 4K UHD video is captured using the full width of the sensor at up to 30 fps, ensuring no loss of lens field of view, a critical feature for underwater video shooters. If a higher frame-rate capture is desired, the Z50 II can capture 4K60p from a native 4K crop (1.44x) of the sensor. Switching to HD achieves up to 120 fps with no loss of field of view and enables dynamic slow-motion capture. Switching between still and video is accomplished via a convenient switch on the camera's rear, and the Z50 II maintains discrete exposure settings for each mode. This makes switching between video and still shooting even easier without requiring excessive changes to settings. The Z50 II's EVF also receives a significant update to its brightness, topping out at 1000 nits. The Z50 II also sees improvements in its autofocus capabilities, especially in subject recognition.
The Nauticam NA-Z50II is designed to work exclusively with the versatile Nikkor Z DX 16-50mm lens, featuring a fixed flat port compatible with our powerful WWL-C wide-angle wet optic and CMC-1 macro optic via the pre-installed bayonet-mount system. The NA-Z50II's form-fitting design and intuitive control placement make the system ideal for traveling photographers who demand a reliable, portable underwater imaging platform.
The compact nature of the Nikon Z50 II is reflected in the design of the NA-Z50II. Compared to the NA-Z50 housing for the original Nikon Z50, the NA-Z50II is built around a clamshell closure that allows for a drop-in installation of the camera with no tray necessary.
The NA-Z50II features intuitively placed, easy-to-reach controls for critical functions, making its integrated, stabilized ergonomic handles Mission Control for your underwater imaging. Textured knobs for the main and sub-command dials are within easy reach of the right handle alongside dedicated video REC and AF-ON buttons.
For video shooters, the Nikon Z50 II maintains separate exposure settings in Still and Video modes, and switching between the modes is done via a convenient switch, which is easily accessed on the top of the NA-Z50II housing. With extensive Auto ISO controls, the NA-Z50II is an ideal platform to create video content with the Z 50's UHD 4K 60p/30p or HD 120p capture.
The Nikon Z50 II has a pop-up flash that can be used to provide accurate TTL flash triggering using integrated fiber-optic bulkheads. A switch on the housing lets the flash be raised or lowered for quick switching between ambient and artificial light shooting.
The NA-Z50II is built around the Nikkor Z DX 16-50mm lens and features a fixed flat port with a pre-installed bayonet mount. Using Nauticam's WWL-C wide-angle optic, the Z50 II delivers unrivaled sharpness, an impressive 140º field of view, and full zoom-through capability. The lens's wet-mate design allows it to be removed underwater and replaced with the powerful CMC-1 macro lens, making the NA-Z50II a true do-anything system. The integrated bayonet mount makes switching quick and easy.
The Nauticam vacuum check and leak detection system is shipped with NA-Z50II as standard equipment. When combined with an optional accessory vacuum valve (PN 25625), this monitoring system provides continuous updates on the watertight 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 an audible and visual indication will occur if water intrudes. The Nauticam system is temperature-compensated, eliminating false alarms caused by changes in outside temperature or by a camera heating up during an action-packed dive.
