Introducing NA-α1

Sony Alpha 1

The Sony α1 is the company's flagship full-frame interchangeable lens camera.  Designed around the new 50.1MP Exmor RS BSI CMOS sensor and the BIONZ XR processor, the a1 is truly a camera which can do it all.  It's 759 point Fast Hybrid Autofocus system offers advanced subject tracking and real-time eye autofocus on both humans and animals.  The optimized processing within the a1 allows it to achieve 30fps continuous shooting at full resolution along with 8K 30p and 4K 120p 10-bit video recording.   

8K 30p recording is possible using the full width of the sensor while 4K 120p uses a 10% crop.  Through a Super 35 crop, oversampled 4K recording is also achievable, via an 5.8K capture area.  For shooters who demand more post production flexibility, 4.3K raw 16-bit recording is possible to an external recorder using the camera's full size HDMI A port.  

The a1 has also received major upgrades compared to its predecessors, including a 9.44M-dot OLED EVF with a 240fps refresh rate.  The newly designed shutter allows for flash sync speeds up to 1/400 sec and the body includes dual card slots supporting either CFexpress Type A or SD UHS-II memory cards.

    The Nauticam NA-α1 Underwater Housing

    Nauticam has supported the Sony Alpha full-frame line since the original a7 with professional grade aluminum housings that offer intuitive access to all the controls and functions of the cameras. As the cameras have evolved, so have the Nauticam housings. The NA-α1 underwater housing provides fingertip access to all key camera controls in a rugged and reliable aluminum underwater housing. Ergonomic camera control access is one of the defining strengths of a Nauticam housing, and the NA-α1 continues this tradition.

    Integrated DSLR-housing styled handles with ergonomic rubberized grips and stainless steel stiffening brackets add stability and accessory mounting points. The NA-a1 also features dual rear thumb-levers that are easily reached from the handle that access three of the most-used controls on the rear of the camera. The right lever actuates the AF-ON and RECORD buttons while the left lever is mapped to the PLAY button.

    Atop the housing on the left side are controls in the form of a MODE dial and FOCUS mode lever. The C1, C2 buttons as well as the EV compensation dial also have direct access from the top of the housing. The C3, which is typically assigned to control switching between the EVF and the LCD screen is easily reachable on the rear of the housing from the left handle.

    Accessory Ports

    The NA-α1 has both an M24 port at the front of the housing for both HDMI 1.4 and HDMI 2.0 connectivity (see sidebar for recommendations) as well as an M14 at the rear for the optional Vacuum Valve (25624). The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system. 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.

    Premium Professional Optics

    Nauticam's wide range of ports and in-house corrective optics are the perfect compliment to the NA-α1's inherent flexibility. Built around the N100 Port System, the NA-α1 supports a wide variety of Sony FE mount lenses, as well as EF mount lenses via adapters. In addition, there are several options available to use the groundbreaking WACP and WACP-2 wide-angle corrective lenses as well as the more compact and in-water removable WWL-1B.

    For example, With the Sony SEL1635GM FE 16-35mm F2.8 GM, the WACP 2 brings the original 105º field-of-view to an impressive 128º with sharper corners, an ~0" minimum focus distance and a more natural looking image than would be provided by a standard glass dome port.

    Flash Triggering

    Both fiber-optic and electrical strobe triggering options are available. The Nauticam Universal Fiber Optical cables attach to the built-in bulkheads atop the housing and feature modular connections for both Sea&Sea-style bushings and INON threaded connections. Triggering is achieved using the optional Nauticam Mini Flash Trigger for Sony (26302) which uses LEDs powered by an on-board coin-cell battery to generate a manual signal that is transmitter via the optical cables to compatible strobes.

    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.
