Nauticam NA-7DMKII para Canon 7D Mark II
The NA-7DMKII Housing
It Is clearly true that the NA-7DMKII is an improvement over the original NA-7D housing, but Nauticam has come so astonishingly far in the last 5 years that this really is not a useful comparison. The NA-7D was an important housing for Nauticam (see the sidebar about that), but Nauticam SLR housings have advanced considerably. Take for example the housing latches. The NA-7D was the last Nauticam housing to use the “old school” stainless steel buckle style latches. The NA-7DMKII takes advantage of the simple yet secure locking latches that have since become famous. These latches are more secure, effortless to close, and eliminate the knuckle busting snap of the old buckles. The NA-7DMKII represents the ideal example of current Nauticam housing design.
Nauticam’s patented Port Locking Lever is as simple to operate as ever, enabling easy port changes without twisting or excessive force. A vacuum reset button inside the port mount also allows the vacuum system to be quickly reset from the port mount making quick lens changes a snap. These touches further reduce the stress of proper gear preparation and allow more time for diving.
Added to these now standard features are ergonomic refinements that further enhance the imaging experience for both still photo and motion imaging enthusiasts. A new dual function lever under the right handle brings ISO and M Fn (used for AF area pattern) out to the fingertips of the user. Nauticam’s signature multi selector pad, found on the Nikon line and NA-70D, provides easy access to all 65 focus points and the ability to move on the diagonals without stair stepping. All of the core functions needed to operate the camera are at the users fingertips, and available by feel.
The NA-7DMKII is the most refined Nauticam SLR housing to date. Every camera function is made easier by careful thought and design, aided by input from photographers who will actually use this camera. The housing borrows the best from recent housings like the NA-D810 and the NA-5DMKIII, and incorporates new enhancements to key exposure controls for both video and still photo users.
New to the Nauticam housings for Canon SLR’s, the NA-7DMKII will feature a lever to activate or deactivate the camera’s popup flash. While this task can be accomplished in the Canon menus, it is easier and faster to disable or enable flash with this lever.
A Personal Note
The Canon 7D holds a very special place in the collective hearts at Nauticam, and for me personally. While it was not the very first camera that Nauticam produced a housing for (housings for the Nikon D90 and D300 preceded it), the 7D was really the camera that put Nauticam on the map. For 4 years, the NA-7D was our bestselling housing, both in terms of units and dollars. To me, the NA-7D represents the genesis of Nauticam’s unique ability to innovate in underwater camera housings. And while the D90/D300 were a terrific start, I am generally a Canon shooter. So if you don’t mind, as we talk about the awesome new 7D Mark II, I’d like to get a little bit nostalgic about the 7D for a moment.
The first time I got my hands on a Canon 7D, one thing struck me… Canon had done what many of us had long hoped for – it had taken professional level autofocus and put it in a camera that was much more manageable than their pro 1D series. It was substantially better autofocus than even their 5D Mark II that had just been released less than a year earlier – faster and more accurate. And while I’d shot the 5D for several years, I have always thought that the APS-C sensor size is ideal for underwater use, and that the extra reach, and smaller wide angle lenses is very useful for topside use as well. I wanted, no, I needed this camera.
In 2010, I managed to get a hold of one of the very first production NA-7D housings. I’d used a prototype on a few dives, but this housing was ready to go diving. It was mine, and I sunk my claws in it and didn’t let go. Looking back, I am amazed at how good the ergonomics were. The housing fit my hands like a glove. Yes, today, the newer designs are even better, but keep in mind that previously, ergonomics on underwater camera housings were totally an afterthought. Before I started with Nauticam, I owned about 6 different housings. While they all had the basics, i.e. you could turn dials and press the shutter, the designs were very rudimentary. But with the NA-7D, someone actually thought about how the hand is positioned on the housing, and how each and every button is used by actual u/w shooters. That attention to detail and to the needs of the operator really started a revolution.
After the first few NA-7D’s shipped, Nauticam did something that, while it sounds fairly ordinary, was in fact quite the opposite. They revised the housing. They changed the design, adding locks to the housing latches and an improved shutter, among other things. Logistically, that is not an easy thing to do for a company. But Nauticam bit the bullet, and did it. New customers got the benefit of the new designs, and many of the existing customers got updates – at no charge. To me, that is when I knew I had signed on to a winning company. The team was not willing to sit idly by. On the contrary; they were moving the innovation bar forward. This company has not stopped since… if anything, the pace of innovation and continued improvement has accelerated. Nauticam came “out of nowhere” (through hard work and determination), and is now the most successful underwater imaging equipment manufacturer on the planet.
And it all started with the 7D.
So please, excuse my sentimentality here. Goodbye 7D, and hello 7D Mark II. I can’t wait to see what amazing images people are able to make with this new version of an old friend.
The APS-C Advantage
What is it about the APS-C sensor size that makes it so ideal for underwater photographer, especially as compared to the 36x24mm full frame sensors? Simply put, it’s lenses. First, for macro, the APS-C yields more “reach” with a given macro lens, and more choices; in particular the Canon EF-S 60mm macro which does not work on Canon’s full frame cameras. The fully kitted macro shooter with the 7DII might have 3 macro lenses, the aforementioned 60mm, the Canon 100m f/2.8 IS L macro, and the Sigma 150mm f/2.8 macro. That is an impressive choice in macro lenses and, by adding a close-up converter lens like the Nauticam Super Macro Converter (SMC), covers the entire spectrum of the macro world, from fish portraiture to the tiny world of super macro.
For fisheye wide angle lenses, APS-C again offers advantages, specifically two of the best and most versatile wide angle lenses available for use underwater. The Tokina 10-17mm is a favorite among underwater photographers, and for good reason. When used on an APS-C camera, this a super-wide 180º fisheye at 10mm, but when zoomed to 17mm the fisheye distortion is greatly reduced and the lens becomes excellent for close-focus-wide-angle or more distant subjects with a 110º fov. The Canon 8-15, used with it’s APS-C range of 10-15mm, is very similar in it’s versatility and produces even sharper images with less aberration.
For rectilinear wide angle, again, the APS-C sensor provides an advantage, this time due to dome port optics. As full frame shooters are aware, it can be a challenge to get sharp corners when using a wide angle rectilinear lens like the Canon 16-35mm. For APS-C, Canon offers the much less expensive 10-22mm and 10-18mm lenses. When these are used with a large dome like the Nauticam 8.5” acrylic dome or the Nauticam 230mm glass dome it is considerably easier to get sharp images, especially in the corners.

Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is available with NA-7DMKII 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 NA-7DMKII ships with a 3rd bulkhead port specifically for installing optional vacuum valves, leaving the user two other bulkhead ports for HDMI, sync cables and other accessories.
