Nauticam NA-EM5III Housing for Olympus E-M5 MKIII (17815)

More than just good looking, the Nauticam E-M5 Mark III hosuing is rugged, and ready to tackle thousands of hours of underwater abuse. Crafted from solid aircraft aluminum, the housing can reach depths of 100m with ease. The effortless (but secure) single rotating housing latch opens the housing back. The camera drops in easily, with no controls needing to be preset. The rear mounted housing o-ring makes maintenance simple. Dual fiber optic synch ports are standard and take advantage of the supplied Olympus accessory flash. To make the most of the E-M5III’s excellent electronic view finder (EVF), Nauticam has crafted an optional rear acrylic display window that includes a mount for installation of Nauticam’s acclaimed 45º and 180º magnified view finders, providing the ultimate in composition and focus ability.

HDMI Connectivity

A forward M16 bulkhead can be used for the optional HDMI 1.4 Bulkhead for use with external monitor housings such as the NA-502 or NA-502B for the SmallHD 502 and 502 Bright monitors.

Viewfinder Options

The E-M5 mark III has an upgraded OLED Electronic Viewfinder.  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.

Rapid Fire Optical Flash Triggering

The E-M5 Mark III camera with the included FL-LM3 flash is limited to 2-3 fps continuous shooting, even when a low manual power is selected in the camera flash menu. In situations where continuous optical shooting is required, Nauticam’s Mini Flash Trigger for Olympus (26306) can trigger external strobes over fiber optic at up to 10 frames per second! The trigger is powered by onboard coin style lithium batteries, with thousands of flashes available from a set.  

The NA-EM5III comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Nauticam Universal Fiber Optic cables provide exceptional light transmission for accurate TTL performance.

Electrical triggering of legacy wired strobe systems is possible via an electrical Nikonos style bulkhead (optional).

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is available with NA-EM5III as standard equipment. Combined with an optional vacuum valve (PN 25624 or 25625), 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.
