Nauticam 70D



Nauticam has just announced their latest housing, built for Canon's EOS 70D. The 70D is the first camera to feature a Dual Pixel CMOS AF Sensor.

What's so great about it? To date, digital SLRs have used advanced phase detection autofocus through the viewfinder and slower contrast detection AF in live view. The Dual Pixel CMOS AF sensor allows use of phase detection AF in both viewfinder and live view, providing fast and accurate autofocus for video and live view shooting. The 70D presents the new standard for video autofocus on DSLRs.


Nauticam 70D Housing - New Features

  • NEW integrated electronic vacuum seal check
  • Constructed with new weight reduction techniques
  • Advanced galvanic corrosion protection
  • Excellent ergonomics
  • Easy lens changes without removing camera from housing

Nauticam 70D



Nauticam announces the release of the NA-70D, the latest in its acclaimed line of precision crafted underwater camera housings. Nauticam is the international leader in innovative housing technology, and the new housing for the Canon 70D capitalizes on that experience. Features include a new, totally integrated electronic vacuum check system - and a host of refinements such as very clever weight reduction techniques and advanced galvanic corrosion prevention.

The Canon 70D is blazing new territory with a spectacular new imaging sensor that turns 80% of the sensor area are into thousands of phase detection autofocus sites, meaning the 70D has the most advanced video focus capability of any current capable SLR. The 70D has taken over for the 7D as Canon's leading prosumer camera, and has all the key ingredients needed to be Canon's flagship APS-C SLR.

The NA-70D takes advantage of the 70D’s extensive new features and brings them into the underwater realm in the most innovative, best engineered (here's some gifts for engineers), and most ergonomic camera housing available... leaving only one question:

What will you shoot with the NA-70D?

The NA-70D Housing

Nauticam pioneered numerous engineering breakthroughs in previous housings that now come standard on the NA-70D. Like the NA-6D, this new housing borrows a control from it's Nikon brethren - the patent pending Multi Controller Pad that is located within easy reach of the right thumb. The Multi Controller Pad allows full multidirectional use of the 8-way controller, while still allowing for the rear command dial to be brought out to the right side of the housing. This control is especially interesting with the 70D using the video autofocus... with a light touch, the user can change the focus during a video clip, allowing for "focus pull" and other advanced shots. No other housing manufacturer has this, and none come close to achieving this kind of ergonomic access to the 8-way controller.

New! Integrated Electronic Vacuum Check and Leak Detection System

Nauticam is pleased to announce that the NA-70D is the first housing to ship with Nauticam's new vacuum system with integrated electronic vacuum and leak detection monitoring system. Now the operator can, at a glance, instantly see the vacuum/watertight 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, a audible and visual indication will occur. The NA-70D 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. More information about the vacuum monitoring system and availability for other Nauticam housings will be forthcoming.

The patented Locking Latch System, used to close and securely lock the housing, has received acclaim worldwide for its ease and functionality. These recessed latches are equipped with safety locks, reduce bulk and require minimal physical effort to engage and release. Port changes have never been simpler than utilizing the Patented Nauticam Locking Port Release. No wrestling, no twisting, no misalignment - just seat and lock.

The Nauticam brand has quickly become synonymous with superior ergonomics in all their underwater camera housings. The NA-70D will only enhance that reputation. Every control is well thought out. Every button, lever and switch is considered not in terms of what is easier for the designer, but what is best for the shooter. A careful look at the engineering and design of the right hand side of this housing reveals this philosophy in practice. The key shooting controls are all easily accessed with the right hand with very little finger movement required. While the controls may look daunting to those new to Nauticam, after a few shots the controls become second nature. Shoot, change aperture, shoot, change shutter speed, flip to video, change shutter speed, start recording, change ISO - all with the thumb and forefinger, and all done quickly and easily.


NA-70D Controls (advantages/usage underwater):

  • Sensitive two stage shutter release (easy to gauge half press; gives fine control over the shutter release)
  • AF-ON Lever (strategically placed for easy thumb focus or thumb focus lock)
  • Front Command Dial directly under shutter release (change aperture effortlessly)
  • Rear Command Dial at left side next to thumb (change shutter speed without removing hand from grips)
  • Multi Controller Pad controls the 8 way selector (easily change focus area, even diagonally)

The Canon 70D Camera

The Canon 70D camera is the 9th camera is the Canon prosumer XX series, dating back to the EOS-D30 and EOS-D60, and through the hugely popular 10D, 20D and on up to the 60D of 2010. This line of cameras was historically the breeding ground for the best of CMOS sensor technology, dating back to the early days of digital SLRs. The 70D is an exceptional camera just based on those credentials. However, this camera has a new trick up it's sleeve as well. Cameras by several manufacturers have taken to embedding a few phase detection sensors into the imaging sensor to help improve autofocus during video recording. Canon has, however, trumped that significantly by integrating phase detection sensors onto every pixel. In effect, the entire sensor becomes a field of phase detectors. Canon claims it is able to use 80% of pixels for this purpose, and the result is an accuracy of autofocus never before seen in SLR video.

The 70D sports 7 frames per second continuous shooting, 1/250 sync speed, built-in WiFi and access to some of the best lenses available. The 70D inherits the exceptionally good white balance system, and Canon SLR video is already known for appearances in movies and television.

Using the 70D's WiFi, it is possible to review images on a smartphone or tablet, without removing the camera from the housing. Connect to a WiFi hotspot or directly to the cameras own built-in hotspot, and enjoy viewing your images on an iPhone/iPad or Android device without opening the housing. Even more amazing, use the EOS Remote on an iPhone to remotely control your camera while it is in the housing. Leave your camera out in the rain while you control it from inside with your smartphone. [Note: WiFi signal strength is infrastructure dependent; these claims have been tested but results may vary depending on conditions. WiFi signals do not propagate in water.]

The year 2012 might have been the year of the full frame camera, but the 70D heralds the revenge of APS-C in 2013. The new Nauticam NA-70D allows the camera to explore the underwater world in style and with all of the elegant engineering, sophisticated ergonomics, clever innovation and shear ruggedness that Nauticam delivers every single day.

Lens Support

The quality of an image is only as good as the glass it was captured with, and Nauticam firmly believes that every lens that makes sense to be used underwater should be supported. The APS-C sensor on the 70D allows use of a wide range of lenses that are widely known for their underwater capabilities. Lenses like the Tokina 10-17mm and the Canon EF-S 60mm are true workhorses in the Canon underwater domain. Nauticam's lineup of ports, together with Zen Underwater dome ports is the most complete and extensive in the industry. Nauticam carefully evaluates new lenses, and is often first to market with support when a new lens is offered. Nauticam also provides the industry’s only locking extension rings in every size potentially required, thus preventing port slippage when using extension rings. Nauticam additionally offers a full range of port adapters allowing existing housing owners to use their current ports, reducing the cost of switching to a Nauticam housing. Port Adapters are available for Aquatica, Ikelite, Inon, Nexus M5 & M6, Sea & Sea NX, Seacam, Subal Version 3 & 4, and Zillion lens ports.

A high resolution camera like the Canon 70D demands perfect focus for optimal results. Fortunately, Nauticam has developed the most user-friendly interchangeable precision viewfinders in the world. The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. 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 allow 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.

Nauticam Viewfinder



Nauticam’s NA-DP4 housing for the Small HD DP4 Monitor can take video performance to another level by rendering the video image in a position more amenable to the shooter. The monitor housing easily mounts to the top of the NA-70D and utilizes the optional HDMI Bulkhead for true HDMI connectivity. Utilizing DP4 features like Focus Peaking, Focus Assist, False Color, 1:1 Mapping and more, this larger monitor vastly improves composition, focus capability and exposure.

The Bottom Line

The Canon 70D represents Canon's commitment to researching and developing the best performing imaging sensors in the SLR world. The APS-C has many advantages in shooting underwater, and is an ideal balance between image quality and ease of use. The pricing of this camera makes is appealing for those wishing to carry a spare body on a long trip. The ability to use somewhat smaller and less expensive lenses like the 10-22mm and the Tokina 10-17mm is a strong virtue, and the 70D is an extremely refined and capable camera. However, the most excitement about this camera is saved for the new sensor. Video shooters get the best of both - SLR video quality with it's capacity for shallow depth of field, combined with focus performance that rivals traditional handicams.  The year 2012 might have been the year of the full frame camera, but the 70D heralds the revenge of the APS-C in 2013. The new Nauticam NA-70D allows the camera to explore the underwater world in style and with all of the elegant engineering, sophisticated ergonomics, clever innovation and shear ruggedness that Nauticam delivers every single day.
