The Olympus OM-D E-M10 Mark IV receives a noticeable bump in resolution to 20MP while fine-tuning and improving the other aspects that have made the E-M10 lineup successful.  Setting it apart from it's direct competitors, the E-M10 offers 5-axis in-body stabilization and the internal flash allows for accurate TTL flash triggering over fiber-optic connections.  Internal 4K 30p video recording makes it an ideal hybrid camera platform in an ultra-portable package.

Port Mount N85




The E-M10 lineup is distinguished by feature rich cameras that leverage the power of the MicroFourThirds system into a portable and economical solution.  The Mark IV receives an upgraded 20.3MP FourThirds sensor that works with the wide array of open-source MicroFourThirds lenses and is paired with Olympus' latest TruePic VIII processor.

Key Camera Specs:

  • 20.3MP Live MOS Sensor 
  • TruePic VIII Processor
  • 121-point Contrast Detection Autofocus
  • 2.36M dot OLED Electronic Viewfinder
  • 4K 30p video capture

The new processor and sensor means improved autofocus via the 121 contrast detection autofocus points.  This also results in better low-light performance at higher ISO values.  The Mark IV also features 5-axis in-body stabilization (IBIS) which allows for smoother video and sharper still images in challenging shooting environments such as those encountered during low light or macro situations.

The Mark IV is truly a hybrid imaging platform with strong video and still image specifications. For video, the O-MD E-M10 Mark IV is able to capture 4K 30p video internally.  Using the pop-up flash over a fiber-optic connection and supported strobes allows for the use of the camera's automatic flash control (TTL). 


The Nauticam NA-EM10IV, similar to the E-M10 Mark IV, builds upon its predecessors to deliver the most intuitive and capable housing for the E-M10 line.  Taking advantage of the Mark IV's improved features requires a housing that places controls where you need them most and allows for the use of purpose built underwater optics.


The NA-EM10IV is designed with Nauticam's Mission Control philosophy in mind.  Essential camera controls are placed where they are needed most.  The NA-EM10IV's design reflects the ultra-portable nature of the camera itself, making the housing system that's truly travel-friendly.  The housing ships with stainless steel stiffening brackets and shutter release extension that work with the optional Easitray II or Felxitray II handle systems to insure the resulting setup is a stable platform for the attachment of lighting or other accessories even when using large strobes or video lights.  The housing also features an M10 threaded mounting point atop the housing for additional flexibility.


The OM-D E-M10 Mark IV features an integrated pop-up flash capable of providing  either a manual or an automatic flash power control signal (TTL).  The Nauticam NA-EM10IV features built-in fiber optic bulkheads to support the use of the camera's TTL when used with supported strobes and fiber optic cables.  There's no need to pop-up the flash before inserting the camera into the housing as it can be engaged via a dedicated control atop the housing.  An optional electronic bulkhead with hotshoe connection is also available but does not support a TTL signal.


The MicroFourThirds lens standard offers a wide variety of lenses to suit any imaging style and the NA-EM10IV's N85 port system offers port combinations for a large number of these lenses.  In addition to standard wide and macro combinations, the NA-EM10IV works with many of Nauticam's purpose built professional underwater optics such as the WWL-1/C and CMC-1/2.  When using a lens such as 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 which is wider than what is capable with a standard wide-angle lens behind a conventional dome port.  These optics are designed for in-water use and provide unparalleled image quality.


The NA-EM10IV comes with Nauticam's vacuum check and leak detection system installed as standard equipment. With the addition of the optional M14 Vacuum Valve (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.

Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand.  No twisting or threading action is required to mount a port, and it locks securely in place with this lever.  Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.


The secure single rotating housing latch of the NA-EM10IV opens the housing back allowing for quick and easy battery or media changes.


Nauticam engineers design philosophy means the NA-EM10IV delivers easy and intuitive access to essential camera controls of the Olympus OM-D E-M10 Mark IV when inside the housing.


Stiffening handle brackets and shutter release extension are included with the NA-EM10IV.  These brackets eliminate any flex or wobble when used with the optional Easitray II or Flexitray II handle systems.
