Nauticam NA-5DMKIV for Canon EOS 5D Mark IV

The Nauticam NA-5DMKIV Underwater Housing

Model Number 17325

While extremely similar to the 5D Mark III and 5DS cameras that came before it, small dimensional changes in the Mark IV body forced a new housing design.

The core control layout, proven by generations of existing housings in the field, is retained here. This design consistency results in immediate familiarity with the control layout for people that have used Nauticam housings before, and a thoroughly refined and field tested design for newcomers to the brand.

The new Nauticam NA-5DMIV housing incorporates technology from the Nauticam housings that came before it, but features enhanced ergonomics, more and better control access, and reduced size & weight thanks to cutting edge manufacturing processes.

Flash Firing
The NA-5DMKIV Housing comes standard with twin Nikonos flash connectors for electrical strobe triggering.

26321 – TTL Flash Trigger for Canon
The Nauticam TTL Flash Trigger is an ideal accessory for the still photographer.

This hotshoe mounted optical flash trigger provides automatic TTL Flash when used with Inon S-TTL and Sea & Sea DS-TTL Strobes connected by fiber optic cables.

The TTL trigger also offers manual triggering, including rear curtain sync, with any compatible slave strobe.


Accurate automatic TTL flash exposure has been a favorite feature of Nauticam photographers using cameras with pop up flashes, and the TTL Trigger unlocks this feature set in the NA-5DMKIV Housing. Powered by a single Canon NB-13L rechargeable battery, the TTL Trigger provides approximately 150 full power flashes.

New in NA-5DMKIV, a window allows the flash trigger status LED to be clearly viewed, and the housing features a power button.  This LED provides important status info, and the power button allows the trigger to be activated underwater.

Optical TTL Strobe Compatibility:
Inon S-2000, D-2000, and Z-240
Sea & Sea YS-D1, YS-D2, and YS-01

An optional LED flash trigger is available for rapid fire optical triggering (manual power), and a new TTL Flash Trigger enables automatic flash exposure with compatible strobes.

Integrated Vacuum Check and Leak Detection System

**************************************

The Nauticam vacuum check and leak detection system is shipped with NA-5DMIV as standard equipment.

Combined with an accessory vacuum valve (PN 25625), 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.

Ease of Use
No competing system is easier to assemble or break down.  The camera drops into the housing with a quick release camera tray.  No controls need to be preset, as housing functions for dials and switches align automatically (on/off, af-m, still photo/video).

The large 120mm housing port opening allows even the largest popular Pro-Canon wide angle lens (11-24mm f/4) to be used, and the camera can even be mounted in the housing with this large lens attached.

Viewfinders


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 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.

Dome ports

Premium Professional Optics
Experienced shooters know a camera is only as good as the lens in front of it, and the same is true when choosing optics for an underwater camera system. Four optically coated glass dome ports (250mm, 230mm, 180mm, and 140mm diameters) and a series of acrylic ports support popular lenses from Canon, Sigma, and Tokina. Port configurations are extensively tested at Nauticam to determine the ideal extension ring length for best performance.

Macro
For macro and super macro shooting, the Nauticam Super Macro Converter is a revolutionary accessory. This is an entirely in-house design, optimized for use in water.  The water contact correction offers the highest overall sharpness, free from chromatic aberration and purple fringing, with reproduction ratios exceeding 2:1 when used with a EF 100mm f/2.8L IS USM Macro Lens.

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.

Housing Locking Latches

The industry's easiest to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening, but are easy to open when needed for a quick battery or memory card change.

Multi-controller Pad & Piano Keys
Located within easy reach of the right thumb, ergonomically operates the 5D Mark IV Multi-controller joystick. Full directional control is available for fast focus point or menu selection. A new focus area button allows easy access to the focus area pattern.
Piano keys bring the Quick Control and SET functions out to the housing handle for quick changes.

Mission Control
The right hand grip features a cluster of key camera controls, all placed ergonomically for fingertip access.
Shutter Release, AF-On, Video Record, Main Dial, Quick Control Dial, M. Fn., Flash Exposure Compensation, and ISO are all conveniently located on the right-hand side of the housing, and easily accessed from the handle.

Card Access LED Window
A new window provides visibility of the camera card access LED. This can be used to indicate whether or not recording in video mode, with much better visibility than the record indicator placed in the top right corner of the LCD display.
