Nauticam NA-A7II Housing for the Sony A7II/A7RII Camera 17414NB
The Nauticam NA-A7II looks quite similar to the Nauticam NA-A7, and the housings are approximately the same dimensions. As those photographers who have experienced the Nauticam NA-A7 housing have discovered, that housing is a stunning blend of aesthetics, ergonomics and functionality and the Nauticam A7II housing only reinforces this mission.
The Nauticam NA-A7II ships with built-in, yet adjustable handles, featuring Nauticam’s famous contoured rubberized grip. The “AF/MF/AEL” button is given special treatment on the right side of the housing with a direct access lever immediately reachable by the right thumb. This allows the button to be programmed for AF-ON meaning “thumb focus” fans can easily have perfect functionality. The shutter release can be accessed at the same time, offering extremely quick focus-to-shoot finger action. Like many Nauticam housings, the play button is brought up to the left thumb, and the three command dials (think shutter speed, aperture and exposure compensation) can be adjusted quickly with minimal reach. The ISO button is within short reach of the right thumb, important for video shooters. Speaking of video, the record button is on the top right, thus eliminating camera shake during video start/stop. The Function Menu button opens up common camera settings to a quick menu, and this button is a short reach with the right thumb. The programmable C3 button is a very easy reach and can be programmed for any of several functions. The housing features a switch to change between the EVF and the LCD providing rapid and secure transition between viewing modes, and supports Nauticam's well renowned viewfinders.
A Nauticam Mini Flash Trigger made specifically for Sony is an available option, allowing the camera to shoot rapid fire with flood free optical cables. The housing includes an M16 bulkhead port for optional HDMI out, Nikonos style sync cable or other external accessory.
The Nauticam NA-A7II accommodates for the larger than expected grip of the camera. Rather than compromise on image quality, the Nauticam designers chose to create ports than take into account this difference, hence a separate entry in the port chart for this housing.
The original A7 and A7R cameras from Sony sparked a huge interest in going full frame for mirrorless. For the underwater photographer, this enthusiasm was quickly diminished by the fairly limited lens selection. Underwater image makers rely on very wide angle lenses and macro lenses, and they were nowhere to be found.
However, Sony recently released the 16-35mm and it is a real game changer. This is a lens from the Sony Zeiss partnership, quaintly dubbed the Sony Vario-Tessar T* FE 16-35mm F4 ZA OSS. It's a terrific rectilinear wide angle zoom that focuses close and demonstrates very good sharpness all around with medium to large sized dome ports. The Nauticam optical glass 180mm dome in combination with the Nauticam N100 to N120 35.5mm Port Adaptor and the Nauticam Extension Ring 50 is an ideal setup for this lens.
For macro lovers, Sony announced a 90mm macro beauty (Sony FE 90mm f/2.8 Macro G OSS), and this lens is supported by the Nauticam N100 Macro Port 105. Also just announced is a new 28mm f/2 lens with an optional fisheye adapter, similar to what Sony did with the fisheye and wide angle adapter on the 16mm lens for the NEX series. This is an appealing way to get fisheye, as it allows multiple configurations with a single lens. Support for the Sony FE 28mm f/2 lens includes the Nauticam N120 8.5 inch Acrylic Dome Port in combination with the Nauticam N100 to N120 35.5mm Port Adaptor and the Nauticam Extension Ring 20 with lock. Here at Mano Photo and Video we recommend the amazing Nauticam WWL-1 wet wide lens. This gives you a 130 degree field of view with an has an amazing close focus ability. The Nauticam WWL-1 in combination with the Nauticam N100 Flat Port 32 is an ideal setup for this lens.
Owners of Canon full frame lenses like the EF 8-15mm f/4L Fisheye USM, EF 100mm f/2.8L Macro IS USM, or the EF 16-35mm f/2.8L II USM lenses will apreciate the ability to use these fine optics with the Sony A7 series. This is made possible with a Metabones adapter (Canon EF Lens to Sony NEX Smart Adapter (Mark III or Mark IV)). These lenses work well on the Sony A7 series, providing both aperture and autofocus control from the camera.
Speaking of Lenses
Nikonos "water contact" lenses are the stuff of legend, but too many of them are sitting in a box in a closet. Time to dust them off! The full frame Sony A7II is a great way to bring those lenses back to action. With the full frame sensor, this Sea&Sea 12mm or the famous Nikonos 15mm behave like they were intended to.
The Nauticam NA-A7II ships with a standard 0.66x viewfinder. This standard optical glass viewfinder is travel friendly and suitable for image makers that care to use the LCD for most framing. Many photographers prefer the ease of a magnified viewfinder with adjustable diopter to take advantage of the excellent EVF in this camera.
Nauticam produces a “straight” 180º enlarging viewfinder and a 45º angled enlarging viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible.
Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is available with the Nauticam NA-A7II as standard equipment. Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing. A simple 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 housing ships with a rear bulkhead port specifically for installing optional vacuum valves, leaving the other bulkhead port available for HDMI, sync cables and other accessories.
