Introducing Nauticam NA-EM5III Underwater housing for Olympus OM-D E-M5 III Camera and OM Systems OM-5 Camera

The Nauticam NA-EM5III Underwater Housing

The Olympus OM-D E-M5 Mark III places the power of the E-M1 Mark II in a compact travel-friendly package and so does the NA-EM5III. Building on the strong lineup of mirrorless camera housings, the NA-EM5III is a feature-rich underwater imaging tool. Our Mission Control design philosophy insures that critical controls are clearly labeled and easy to access with intuitive placement.

Stainless steel stiffening brackets and a shutter release extension, which are compatible with the optional Easitray II or Flexitray II tray systems are included with the NA-EM5III. An M10 threaded accessory mounting point is also ready to accept the optional M10 strobe mounting ball for additional accessory mounting flexibility.

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.

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.
