THE NIKON D750
One of the hottest releases from the Photokina 2014 Imaging Fair in Cologne, Germany, Nikon D750 has received attention from both amateur and professional image makers alike, and is poised to become one of the most popular underwater cameras of 2015.
The D750 is essentially a 24.3 megapixel version of the class leading D810. It features the same incredible 51 point autofocus system, Image Processor, 91,000 pixel color metering sensor, 3.2” 1.2m dot lcd screen, professional grade build quality, and excellent ergonomics. The sensitivity of the autofocus system is actually improved, and D750 can achieve 6.5fps continuous shooting for fast moving subjects.
A new tilting LCD screen allows for convenient live view composition with the camera overhead or low to the ground.
24.3 megapixels is a tremendous amount of resolution, more than the highest resolution offering from Canon, and sufficient for large prints. At a price point $1000 less than the D810, the D750 delivers outstanding resolution, image quality, autofocus performance, and overall usability in a smaller body that is often better for those with small hands.

THE NA-D750 UNDERWATER HOUSING
The operation of the housing in water is intuitive, comfortable, and ergonomic. Key controls are placed within easy reach of the housing handles, exactly where the underwater photographer needs them. All controls are clearly labeled, and several button and lever formats are used to allow operation by feel.
Core camera functions such as shutter release, aperture, shutter speed, live view, info, exposure compensation, depth of field preview, Fn, flash exposure compensation, focus mode, AF/M, and zoom are all located at the users fingertips. Dual thumb levers pull important functionality from the back of the camera out to the housing handles, allowing quick access to Video Record, AF-On (for thumb activated focus), ISO, and Image Playback. The patent pending Multi Controller Pad replicates this control from the D750 Camera, allowing easy focus point selection, even on the diagonals.
Nauticam housings are as easy to use on the dive deck as they are in the water. Nauticam's patented Port Locking Lever is simple to operate, 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, when making quick lens changes. The housing locking system is easy to operate, and secure. These touches further reduce the stress of proper gear preparation.
The D750 LCD can be tilted up a 15 degree angle, assisting low angle composition and video framing.
Precision requires vision: A high resolution camera like the Nikon D750 demands perfect focus for optimal results. Fortunately, Nauticam has developed the most user-friendly interchangeable viewfinders available.
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.
INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM
The Nauticam vacuum check and leak detection system is available with NA-D750 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. The operator can, at a glance, instantly see 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-D750 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.
