Canon EOS R3 NA-R3 Nauticam

The Nauticam NA-R3 professional aluminum underwater housing for the Canon EOS R3 mirrorless full frame camera is a tru hybrid shooting solution, just as the R3 itself.  Nauticam has continuously supported both the Canon pro-level DSLR lineup as well as the growing full-frame RF-mount mirrorless cameras with innovative underwater housings and the new NA-R3 is the combination of all those technologies.  Blending elements of our 1D series housings with those for the R series, the NA-R3 will be the most capable housing for the R3 available.

MISSION CONTROL

Nauticam engineers design each housing to insure that controls are placed where they are needed most and within easy reach of a natural hand position.  The NA-R3 features large knurled control dials for the main and sub-command dials as well as an additional shoulder dial for the customizable control wheel of the R3.  A fourth control wheel, near the front of the left handle can articulate the ring of the optional EF-to-RF lens adapter when using EF lenses.  There is a dual thumb lever on the right side for Record and AF-ON as well as single levers for M-Fn and Fn2.  A lever on the left side actuates the Pv control which can change between exposure preview and OVF simulation modes on the EVF.  An additional dual thumb lever on the left side is for Playback and Magnification.

HDMI 2.0 AND MOUNTING POINTS

The R3 can output clean 6K 60p over HDMI and the NA-R3 features a large bore M24 bulkhead to support an HDMI 2.0 connection to an external monitor or recorder.  Mounting the monitor or recorder or other accessories is even easier with 3x 1/4"-20 mounting holes as well as an additional M10 mounting point atop the housing.  Check the resources sidebar for supported monitor/recorder housings and recommended accessories.

FLASH TRIGGERING

Flash triggering can be accomplished via the two included M14 electronic bulkheads (One is pre-installed in the M24 bulkhead via a removable M26-M14 adapter).  If using fiber-optic triggering, the built-in fiber optic bulkheads can be used with either the optional manual LED or TTL-flash triggers to provide the desired type of strobe power control.

PREMIUM PROFESSIONAL OPTICS

The NA-R3 is built around the N120 Canon RF-mount Port System which supports a wide array of Canon RF mount lenses with a selection of optical glass and acrylic ports.  With lens-removal controls for both EF and RF mount lenses, the NA-R3 can support both lens mount types without modification to the housing.  The EF-RF lens adapter is accommodated inside the housing which allows for the use of the N120 Canon EF-mount Port System without any additional extension rings.  When switching between an EF and RF lens, the camera must be removed to install or remove the adapter.  The Nauticam lineup of Premium Professional Optics can deliver unparalleled optical quality and expanded creative options. When used with the Canon RF 14-35 F/4 IL USM lens, the WACP-2 creates a stunning 140º field-of-view while maintaining an incredibly natural looking image and excellent corner sharpness.  The SMC-1 delivers 2.3x macro magnification to the RF 100mm macro lens while the SMC-2 delivers 3.3x.

VACUUM CHECK AND LEAK DETECTION SYSTEM

The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system, requiring only the optional M16 Vacuum Valve (25625). 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.
