With the Canon EOS R camera, underwater image makers are seeing a full-frame mirrorless camera that incorporates Canon's dual-pixel autofocus! The EOS R has the ability to be used with the EF lens lineup via an adapter, or the new RF mount lenses with breakthrough features.  The EOS-R features a 30.3 MP Full Frame CMOS sensor using the new RF lens mount and a 3.7M dot electronic viewfinder.

The Nauticam NA-EOS-R Housing

The NA-R underwater housing embodies Nauticam's drive for innovation.  For many, the EOS R is a move from a full-frame Canon DSLR.  To support both the legacy EF and native R-mount lenses, Nauticam has equipped the NA-R with an N120 port mount.  This large diameter port system allows all existing EF-mount DSLR configurations to be used, and is prepared to accommodate the R Mount lenses that will come.

The compact EOS R camera body allows for a small travel friendly form factor, but the housing itself is a professional grade tool.  The control layout will be instantly familiar for anyone with experience using Nauticam housings for Canon DSLR cameras.

The Canon EOS R Camera

The Canon EOS R is noteworthy as Canon's first full-frame mirrorless camera, but also impressive is the number of additional features that are now available with the introduction of the RF lens mount.  The RF lens mount features a 54mm diameter that allows for larger rear lens elements that are closer to the sensor, providing increased corner and outer edge sharpness.  The lenses can also be more compact than equivalent coverage area EF-mount lenses.  RF lenses feature a customizable control ring that can be assigned to control various exposure settings.  With RF lenses, manual focus is controlled electronically, allowing the direction of rotation of the manual focus ring of the lens to be configured via the camera menu.  

The EOS-R is also capable of using the extensive EF-mount lens lineup via three optional adapters. A simple EF to R adapter, one which supports the customizable control ring and another that features a drop-in filter mount are available.

Features that have made Canon DSLR and Cinema cameras a favorite of underwater image makers are present in the EOS-R. Fast and accurate Dual Pixel Autofocus, 4K Canon Log video recording, and the large 30.2MP CMOS full-frame sensor with outstanding dynamic range and color fidelity have all made their way into this compact and cutting edge camera body.

RF and EF Mount Support

Canon's EF to RF mount adapters can be mounted on the camera before installation into the housing.  When using the EOS R with the adapter and a supported EF lens, the port and extension ring arrangement will be identical to the same setup on a Nauticam Canon N120 DSLR.  Existing Nauticam DSLR housing owners can easily share lens port accessories with the new NA-R housing.

Two lens release buttons, one for RF and one for EF lenses used with the optional Canon adapter, are located on the front of the housing to make lens removal through the port opening simple.

An additional control wheel is located on the left side of the housing and will interface with the control ring on the supported EF to EOS-R Mount Adapter with Control Ring using the optional gear (PN 19561).

 Intelligent Control Placement

Nauticam engineers are obsessed with providing the most convenient access possible to all key camera controls.  This Mission Control philosophy extends to the NA-R where a dual thumb lever and dual sub-lever are placed by the right handle.  The upper thumb lever activates the "AF-On" and the lower the "Info" buttons while the sub-lever corresponds to the "M-Fn" and "Record" buttons.  Near the left handle is a thumb lever for "Playback" as well as a dedicated switch to change from using LCD to the EVF. 

Large knurled and rubberized control dials access the camera's "main" and "sub" command dials. The two-stage trigger allows for smooth focus and firing activation. Additional buttons for "Menu" and "Focus Point Selection" are also easily reached from the handles.

Flash Triggering

Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (PN 26301) or a TTL Flash Trigger (PN 26321) that use the built-in fiber optic bulkheads with optional fiber-optic cables to trigger supported strobes.  For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available.

Key Features 

Patented Port Locking System

The NA-EOS-R features Nauticam's signature port locking system.  Ports can be easily installed and securely locked in place.  The NA-R will support both RF and EF mount lenses through the N120 Port System.

Housing Locking Latches

The industry's easiest to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening, but are easy to open when needed for a quick battery or memory card change.

HDMI Output Support

The EOS R camera supports 10 bit HDMI video output at UHD resolution (3840 x 2160) at up to 30p.  An external monitor or recorder can be used with the M16 HDMI bulkhead (PN 25033) and HDMI (D-C) cable in 190mm length (PN 25036) which come standard in any Nauticam monitor housing package.
