The Canon EOS M3

EOS M3 is a high performance 24 megapixel APS-C mirrorless body that signals Canon's new commitment to the mirrorless segment.  EOS M3 improves upon its predecessors in nearly every way, but most noticeably autofocus.  The system uses 49 on sensor phase-detect points that result in focus speeds up to 6 times faster than the original EOS M.

Ergonomically the body is much improved.  Individual command wheels access shutter speed and aperture, along with a dedicated mode dial, and an exposure compensation dial.  These physical dials give enthusiast photographers direct, convenient control access that perfectly complements the already excellent Canon EOS M touch screen interface.  The EOS M3 also features a nicely contoured grip that further improves handling.

Canon EOS M3 Key Features

  • 24.2 MP CMOS sensor
  • 49 on sensor phase-detect AF Points
  • 3", 1 m-dot ClearView II TFT-LCD Panel
  • 4.2 fps continuous shooting speed
  • 1920 x 1080 Full HD Video at 30 frames per second with manual exposure control
  • HDMI Output

Nauticam NA-EOSM3

The NA-EOSM3 housing delivers ergonomic control access, complete functionality, and a comprehensive lens port lineup.  Nauticam leads the underwater housing market in mirrorless interchangeable lens camera support, and the expertise gained from dozens of previous models is fully integrated into the NA-EOSM3 design.

Essential functions are placed for fingertip access at the sculpted right grip.  Key controls, such as f-stop, shutter speed, exposure compensation, focus point, and the star button (*) are all easily accessed from the housing grip.  The highly refined Nauticam shutter release lever provides tactile feel of half press, critical for accurate pre-focus.

Camera setup is designed to be simple, and fool proof.  The slides into the housing with all controls perfectly aligned, and nothing needing to be pre set.  A robust cam lever lock ensures perfect alignment.  It is impossible to close the housing back door with the camera incorrectly installed, or the camera tray unlocked.

New Shutter Release Extension

NA-EOSM3 ergonomics are perfectly engineered for a "right hand on the grip" shooting style.  Some users, especially those diving in cold water with dry gloves, need alternate ways to hold and operate the camera.

This included shutter release extension and stainless steel handle bracket provide convenient shutter release access when used with the Nauticam Tray and Handle Systems.

Nauticam Vacuum Check System

The Nauticam vacuum check and leak detection system inspires confidence, with constant LED monitoring of the water tight system status.

NA-EOSM3 includes vacuum monitoring and leak detection circuitry as standard equipment.  When paired with an optional vacuum valve (sold separately), the operator can, at a glance, instantly see 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.

The NA-EOSM3 ships with a 2nd bulkhead port specifically for installing optional vacuum valves, leaving the primary bulkhead ports for HDMI, sync cables and other accessories.

Recommended EOS Lenses (used with EF-EOS M Adaptor)


EF-EOS M Adaptor with Canon 8-15mm f/4L Fisheye USM
