Nauticam NA-EM1III Underwater Housing

The Olympus OM-D E-M1 is characterized by its combination of extreme customizability and impressive stabilization in a compact hybrid-shooting package.  The Nauticam NA-EM1III, similar to the E-M1 Mark III is a refinement of it's predecessors. Nauticam has produced housings for wide range of Olympus cameras from the compact Tough TG series to the PEN and OM-D lines.  Throughout the evolution of Olympus' cameras, Nauticam has adapted our design to help image makers get take full advantage of every camera advancement.  More than a simple waterproof case, the NA-EM1III integrates with the EM-1 Mark III to adapt and improve upon the camera's features for underwater shooting.

Misson Control

Regardless of where a dial or button may be found on the camera body, Nauticam engineers make sure it is located where it is needed most on the housing.  This Mission Control philosophy drives the design of every housing and provides for the most intuitive and easy to use housings available.  The NA-EM1III features a thumb lever, easily accessed from the ergonomic rubberized right handle that actuates the customizable AEL/AFL control.  Typically, for underwater use, this control is assigned to trigger momentary autofocus.  This back-button autofocus method prevents the camera from refocusing between shots, allowing the user fine control over a shot's focus and is critical whether shooting macro or fast moving wide-angle subjects.

Flash Triggering

The OM-D EM-1 Mark III can be used with the optional Olympus FL-LM3 flash inside the NA-EM1III to provide accurate TTL flash triggering through the integrated Sea&Sea style fiber optic bulkheads.  For high-speed manual flash triggering, the optional Mini Flash Trigger for Olympus (26306) can be used.  The trigger is powered by onboard coin style lithium batteries, with thousands of flashes available from a set.  Electrical triggering of legacy wired strobe systems is possible via an electrical Nikonos style bulkhead (optional).

Premium Professional Optics

A camera system is only as good as the optics placed in front of it.  Nauticam's extensive line of dome and flat ports support a wide variety of Micro Four Thirds lenses.  For even higher image quality and versatility, the NA-EM1III can be used in conjunction with Nauticam's lineup of Water Contact Optics.  For example, with the Olympus 14-42mm f/3.5-5.6 EZ Lens or ED 12-50mm F3.5-6.3 EZ*, the Nauticam WWL-1 provides a full zoom through ultra wide-angle 130º field of view. 

Magnifying Viewfinders

A clear view for fine focus and composition is critical for successful underwater photography, and nothing beats a magnifying viewfinder. These viewfinders use distance, not closeup vision, and provide a large, clear view of the high resolution Olympus electronic viewfinder. Available in Angled 45º (PN 32205) and Straight 180º (PN 32204) formats, both viewfinders have external dioptric adjustments for dialing in perfect correction matched to the photographer's eyesight.

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is available with NA-EM1III as standard equipment. Combined with an optional vacuum valve (PN 25624), this monitoring system provides constant updates on 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.
