OPTICS

Sharing the same lens port accessories as the Nauticam NA-A9 and NA-A7II housings, a list of thirteen Sony FE mount lenses is currently supported. An adapter allows the entire N120 DSLR lens lineup to be used as well, supporting the popular Canon EF lenses attached to the a7R III with an EF to Sony E mount lens adapter. Also available is an adapter to attach the water contact UW-Nikkor series lenses originally used on the Nikonos underwater rangefinder systems. From ultra-wide fisheye lenses to long macros, the Nauticam A7RIII system has all focal lengths covered.

MODERN OPTICS FOR IN WATER USE

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.

FLASH TRIGGERING

An optional LED flash trigger (26302) provides rapid-fire strobe triggering with optical slave strobes over fiber optic cables. A new universal fiber optic cable set (26216) provides reliable triggering with all popular optical slave strobes!

Flash systems that use electrical sync cables can be connected to a Nikonos Bulkhead and Hotshoe (25056).

Nauticam's 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 timepiece, the complexity under the hood results in a trouble-free user experience that just works and keeps working for years to come.
