NA-A9 Housing for Sony Alpha 9
Sony A9 :: The New Pro Mirrorless Standard
Aimed squarely at professional image makers, the Sony Alpha 9 provides 20 frame per second continuous shooting with full autofocus and UHD 4K Video. A new 24 megapixel full frame Stacked CMOS sensor with excellent image quality, even at high ISO, and ultra-fast readout that enables the blazing speed this camera is capable of.
The Nauticam NA-A9 Housing
A professional housing befitting of a flagship camera, the NA-A9 underwater housing provides fingertip access to all key camera controls in a rugged and reliable aluminum underwater housing. Critical camera parameter changes are made from the handles, without awkward reaches.
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.
Sharing the same lens port accessories as the Nauticam NA-A7II housing, a list of thirteen Sony FE mount lenses are currently supported. An adaptor allows the entire N120 DSLR lens lineup to be used as well, supporting the popular Canon EF lenses attached to the A9 with an EF to Sony E mount lens adapter. Also available is an adaptor to attach the water contact UW-Nikkor series lenses originally used on the Nikonos underwater range finder systems. From ultra wide fisheye lenses to long macros, the Nauticam A9 system has all focal lengths covered.
Modern Water Contact Optics
Inspired by the water contact lens designs of decades before, Nauticam is continually developing new optical accessories that raise the bar of what is possible in underwater imaging. Designed with modern lens design software, and fully optimized for in water use, these lenses provide significantly better performance than an in air lens behind a dome or flat port alone.
Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is shipped with NA-A9 as standard equipment. Combined with an accessory vacuum valve (PN 25624), 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.
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.
An optional LED flash trigger (26302) provides rapid fire strobe triggering with optical slave strobes over fiber optic cables. Flash systems that use electrical sync cables are connected to a Nikonos Bulkhead and Hotshoe (25056).
Nauticam build quality is simply unmatched, using cutting edge product design and modern, innovative manufacturing techniques that result in trouble-free reliability. A bit like a fine Swiss time piece, the complexity under the hood results in a trouble free user experience that just works, and keeps working for years to come.
