The NA-G5XII builds upon a long line of Nauticam housings that include the original G5 X and three versions of its G7 X sibling. The housing is built around the expanding N50 Interchangeable Port System.
NOTE: the NA-G5XII does not support the use of the camera's pop-up EVF inside the housing.
The NA-G5XII features a two-stage trigger, large lockable zoom lever and knurled dials for the MODE and Exposure Compensation control dials. A textured dial at the front of the housing, within easy reach of a natural hand position controls the lens control ring of the camera. On the rear of the housing, in addition to the four-way controller are buttons for the customizable "*" button which can be assigned as an AF-ON control to facilitate the popular back-button method of autofocus control as well as RECORD button. Using this method, autofocus activation is removed from the trigger and is controlled solely by pressing the AF-ON control button to prevent refocusing by the camera between shutter presses. The RECORD button can also be assigned a variety of other functions such as activating the 30fps RAW Burst Mode.
HDMI VIDEO OUTPUT
With full-sensor width UHD 4K 30p clean video signal output over HDMI the G5 X Mark II can be paired with an external monitor like the SmallHD 502 Bright to aid with composition and accurate judging of focus and exposure. The NA-G5XII housing's M16 bulkhead can be outfitted to support HDMI output via HDMI 1.4 to Nauticam Monitor housings such as the NA-502B. See the Recommended Accessories listing in the sidebar for details.
PREMIUM PROFESSIONAL OPTICS
The N50 interchangeable port system means the NA-G5XII can take advantage of Nauticam's line of premium professional underwater optics. The housing ships with the N50 Standard Port which allows for the use of the camera's full 24-120mm equivalent zoom range as well as the CMC-1, CMC-2, and SMC-1 (2.3x Magnification) Macro Optic when equipped with the optional M67 Flip Diopter Holder (25107). Note, the SMC-1 provides optimum results when used past 90mm equivalent zoom length and will vignette at wider fields-of-view or farther focal distances.
To return the lens' original field of view, the NA-G5XII can be used with the N50 3.5" Acrylic Dome Port. This port also allows for the use of the full zoom range but cannot accept diopters.
The Nauticam WWL-1 (83201) and WWL-C (83203) Wet-Wide Lenses bring professional wide-angle performance to the NA-G5XII providing a 130º field-of-view and 0" minimum focus distance. The WWL-1 works within the 28-50mm zoom range, while the WWL-C works in the 24-50mm range. To use either the WWL-1 or WWL-C the NA-G5XII requires the optional N50 Short Port 25 with Bayonet Mount (38703). The Bayonet Mount System allows for easy removal of the lens underwater to further expand the flexibility of the system.
The NA-G5XII features built-in optical bulkheads that transmit the camera's internal flash via optional Universal Fiber Optic Cables (26216) to supported external strobes. The internal flash can be raised and lowered inside the housing to facilitate fast switching between natural light and artificial light situations.
INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM
The Nauticam vacuum check and leak detection system is shipped with NA-G5XII as standard equipment. Combined with an accessory M14 Vacuum Valve II (PN 25624), this monitoring system provides constant 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 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.
