NA-R5C

The Canon EOS R5 C Camera

The Canon EOS R5 C is the latest in Canon's full-frame mirrorless camera lineup which has gained unprecedented demand.  This camera has truly set new standards for a hybrid mirrorless camera that offers both high end cinema and still photo features.  It utilizes the RF lens mount which has the same large 54mm diameter but the ability to have larger rear lens elements that are closer to the sensor gives increased corner and outer edge sharpness. 

The R5 C uses a 45MP full frame CMOS sensor with Canon's beloved Dual Pixel Autofocus.   It is also capable of recording internal 8K 60p video in Canon's Cinema RAW Light format and 4K 120p in 4:2:2 10-bit without cropping the sensor.  With a the flip of the switch, you can change the R5 C into a professional still photo camera and share all the same specs as the Canon R5.  The EOS R5 C can also use the large 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.

The Nauticam NA-R5C Underwater Housing for the Canon EOS R5 C Camera

The NA-R5C underwater housing follows suit with Nauticam's drive for innovation. The Canon R5 C presents shooters with the ability to use both the available legacy EF lenses via an adapter in addition to their native RF optics.  To support both the legacy and native lenses, Nauticam has integrated the NA-R5C into the N120 port system. Canon's EF to RF mount adapters can be affixed to the camera before insertion into the housing. When using the EOS R5 C inside the housing 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 Cinema EF Mount Port Chart. As the RF lens lineup continues to emerge, more dedicated port and extension ring combinations will be listed on the Port Chart. 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.

Mission Control

Nauticam engineers are obsessed with getting the underwater image maker unfettered access to all the necessary controls, with as many within easy reach of the ergonomic rubberized handles. This Mission Control philosophy extends to the NA-R5 C 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 "Menu" or "Q" 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", "Focus Point Selection" and others are also easily reached from the handles.

An optional 16703 Control Kit for the NA-R5C is available to use with the Drop-In Filter Mount Adapter EF-EOS R.  You can access the Canon Control Ring and Drop-In Filter Mount Adapter from the top left side (ADAP FN knob). 

External Battery Pack

To support 8K 60p internal Canon Cinema RAW Light recording, an external power source is required.  At the bottom of the housing is space to accomodate a USB-C power bank.  Here are two known compatible batteries with more to come:

• Anker PowerCore III 19,200mAh Huge Cell Capacity 45W Power Delivery Portable Charger (Dimensions: 169x79x22.4mm)

• ZMI 20000mah 65W PD battery (Dimensions: 160.4x81.8x21.5mm)

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.

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection electronics are shipped with the NA-R5C as standard equipment. Combined with an optional accessory 25625 M16 Vacuum Valve II 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.
