Nauticam housing NA-A7II for Sony Alpha a7 II, a7R II

Includes handles; dome ports must be purchased separately.

The NA-A7II is an incremental improvement over the outstanding NA-A7 housing, and is the ultimate underwater machine for full frame mirrorless image making.

The NA-A7II Housing

**Available with and without bulkhead: Choose the housing with bulkhead to use sync cables with your strobes. Choose no bulkhead if using the flash trigger, or shooting video only. ***

The NA-A7II looks quite similar to the NA-A7, and the housings are approximately the same dimensions. As those photographers who have experienced the NA-A7 housing have discovered, that housing is a stunning blend of aesthetics, ergonomics and functionality and the A7II housing only reinforces this mission.

The 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 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. 

Lens Matters

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, the recently released 16-35mm is a 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 180mm dome is an ideal choice for this lens. 

For macro lovers, Sony two days ago announced a 90mm macro beauty (Sony FE 90mm f/2.8 Macro G OSS), and this lens will be supported as soon as possible after it is shipped (slated for July). Also just announced is a new 28mm f/2 lens with a 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. Look for more info about Nauticam support for this lens when it ships (slated for May). 

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 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 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 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. 

Viewfinder Options

The 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 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.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

Update 18/12/2020: There are some production delays at present that may increase wait times on items like housings. We apologise for the inconvenience. If there are any delays with your order, we will communicate this immediately.

How do you ship my orders?

We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

Covid-19

We hope you, your families and friends are safe and healthy during the current Covid-19 situation.

As you may know we are a small team at Sea Tech Ltd. Our team has zero close contact with people outside our bubble.

We wish to assure you, that when we begin fulfilling orders on 28 April, we will be following the government health guidelines surrounding safe operating procedures. Hygiene basics such as hand washing, coughing/sneezing protocols as well as the wearing of appropriate protective equipment such as face masks.


We are continuing to follow the regular updates to government health guidelines and initiatives regarding Covid-19.


Please do not hesitate to contact us if you wish to discuss any aspect of our delivery service via Courier Post New Zealand.

We wish you all the best during these challenging times.

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.
