Nauticam designed the NA-R5 to solve one of the biggest transition headaches for Canon shooters moving into mirrorless underwater: how to support both legacy EF glass and newer RF lenses without forcing a full system reset. This Nauticam underwater housing integrates the Canon R5 into the proven N120 port system, allowing shooters to continue using existing EF lenses via Canon’s EF-to-RF adapters, while still being ready for native RF optics as the lineup expands. From a setup standpoint, this is one of the cleanest mirrorless transitions we’ve worked with. Canon’s EF-to-RF adapters can be mounted to the camera before insertion, and when paired with supported EF lenses, port and extension combinations mirror those used on Nauticam Canon N120 DSLR housings.

 

In practice, that means many shooters can reuse familiar port configurations while planning future upgrades around RF lenses listed on the Nauticam port chart. Two dedicated lens release buttons—one for RF lenses and one for EF lenses used with the adapter—make lens changes through the port opening straightforward and frustration-free.

 

Despite its technical depth, this is also an excellent entry-level Nauticam housing in the sense that everything required to go diving is built in. Out of the box, this Nauticam Canon underwater housing is genuinely dive-ready. The NA-R5 Kit ships with Nauticam’s integrated vacuum check and leak detection electronics already installed, removing the need for aftermarket monitoring solutions. A manual flash trigger for Canon is included, utilizing the built-in fiber-optic bulkheads for reliable strobe firing with supported fiber-optic strobes. This Nauticam Kit also includes a carry lanyard, which may sound minor, but it’s something our staff appreciates when handing the housing up to a boat crew or managing entries on liveaboards. In short, the essentials are covered so you can focus on ports, lenses, and lighting—not baseline safety or triggering hardware.

Best for: Canon R5 shooters entering underwater photography who want long-term system flexibility.

Not for: Users expecting automatic TTL without configuring triggers or those unwilling to follow port charts closely. Supports both EF (via adapter) and RF lenses within the N120 port system.

Port and extension setups for EF lenses match Nauticam N120 DSLR configurations.

Built-in vacuum check and leak detection are included, ready to dive, without worries of floods.

Key Features of the Nauticam Canon R5 Kit:

RF and EF Mount Support

The Canon EOS R5 works seamlessly with both EF and RF mount lenses. Our Nauticam housing makes sure you can use both types of lens to your hearts desire! The housing supports both RF and EF Mount Adapters which can be installed on the camera before putting it inside the housing. Existing Nauticam DSLR housing owners can easily share lens port accessories with the new NA-R housing.

 

 

Intelligent Control Placement

Nauticam engineers make it their goal for every camera control to be just a finger away from your hand.  With this housing, pressing the shutter is as easy as doing it on land. Nauticam has built a dual lever on the back of the housing for back button autofocus and recording control. 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 - a clear benefit from using a Sony housing! 

Large 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

The housing can accomodate the optional Flash Trigger or TTL Converter that will utilize the built-in fiber optic bulkheads. For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available.

 

Patented Port Locking System

The housing features Nauticam's signature port locking system.  Ports can be easily installed and securely locked in place. It's just the press of a button and the turn of a lever!  The NA-R5 will support both RF and EF mount lenses through the N120 Port System.

 

 

 

Housing Locking Latches

Closing the back of this housing is safe, secure, easy, and requires very little strength to operate. The latches are safely locked to prevent accidental opening, but are easy to open when you need to make a quick battery or memory card change.

 

 

HDMI Output Support

The EOS R5 is a top video camera that can support 8K RAW recording. That's a lot of processing power and storage space. We recommend using an external monitor or recorder which can help you visualize your scene and store even more footage or keep it redundant.  An external monitor or recorder can be used with the M16 HDMI bulkhead and HDMI (D-C) cable in 190mm length which come standard in any Nauticam monitor housing package.

 

 

 

Stainless Steel Handle Brackets

Stiffening handle brackets are included with the housing.  These brackets eliminate any flex or wobble when using big strobes, and provide multiple attachment points for lanyards or other accessories.

 

 

Premium Professional Optics

The NA-EOS-R5 is designed around the N120 Port System and when used with supported lenses allows for the use of a variety of Nauticam water contact optics such as the WACP-2, as well as the SMC-1 and SMC-2 super macro converters.
