NA-A7RIV for Sony Sony a7R Mark IV

Sony Alpha a7R IV

The Sony a7R IV is the company's fourth generation, high-resolution full-frame mirrorless camera. The 61.0-megapixel full-frame Exmor CMOS sensor combined with BIONZ X imaging engine delivers unprecedented resolution, fine gradation, and low noise. Relative to previous generations, it promises more robust build quality, refined controls, the company's latest autofocus.

Despite its high resolution, it can shoot at up to 10 frames per second with full autofocus and shoot 4K video either from the full width of its sensor or from a Super 35 crop. It also gains a 16-shot high-resolution mode that can be used to generate 240MP images of static scenes

Sony Alpha a7R IV Key Specifications
  • 61MP BSI CMOS full-frame sensor

  • Powerful yet easy-to-use AF tracking system

  • 10 fps burst shooting (12-bit Raw mode)

  • 5.76M dot OLED viewfinder

  • 4K video from full sensor width (sub-sampled) or oversampled from Super35 crop

  • S-Log 2, S-Log 3 and 'HLG' video modes (8-bit only)

THE Nauticam NA-A7RIV underwater housing

The NA-A7RIV 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-7RIV continues this tradition. Essential camera parameter changes are made from the handles, without awkward reaches. 

The NA-A7RIV housing inherits the core design elements from the Nauticam pro DSLR range, and bundles them in a more compact package.  A patented port locking lever allows lens changes to be made in seconds. Opening the housing for quick battery and media changes is fast and easy with the locking housing latches. All aspects of the system are a seamless extension of the camera.

New features of the NA-A7RIV include a M24 accessory port for HDMI 2.0 output connection, two more accessory ports on the rear housing: M14 x1, M16 x1 and increased zoom/focus gear ratio on the housing, which means faster and more precision control of the lens for video. There is also a new N100 to N120 35.5mm port adaptor II, (37305) featuring a gear box, for faster zoom and more focus control. NOTE: (37303) N100 to N120 35.5mm Adapter is NOT COMPATIBLE with the  NA-A7IV.

New features of the NA-A7IV

  • Increased zoom/focus gear ratio on the housing, which means faster and more precision control on the lens for video
  • New handle bracket design to enhance the stability of handle control underwater
  • New sealing O-ring design for LCD window
  • M24 accessory port for HDMI 2.0 output connection
  • Two more accessory ports on the rear housing: M14 x1, M16 x1

Features

HDMI 2.0 support

The NA-A7RIV features the larger-bore M24 bulkhead that allows for the use of Nauticam HDMI 2.0 cables for connection to recorders such as the Atomos Ninja V.

Patented port locking system

Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand.  No twisting or threading action is required to mount a port, and it locks securely in place with this lever.  Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.

Vacuum check and leak detection system

Combined with an optional vacuum valve (PN 25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing via a simple color-coded LED lighting system.

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.

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.
