Nauticam Canon EOS R5 II Underwater Housing NA-R5II

Introducing the Nauticam NA-R5II Underwater Housing for Canon EOS R5 Mark II Camera

The Canon EOS R5II is the next iteration of the widely popular Canon EOS R5 and retains many of the features that were attractive to underwater image makers. Firstly, and most excitingly video shooters now have access to 8K 60 Raw/4K 60 SRAW/4K 120 10-bit Video. The Canon EOS R5II retains its 45MP full-frame mirrorless sensor that utilizes Canon's new RF lens mount and also has next-generation Dual Pixel autofocus.

Introducing NA-R5II

The Canon EOS R5II Camera

The Canon EOS R5II is the latest in Canon's full-frame mirrorless camera lineup which has gained unprecedented demand as it has made considerable improvements from its predecessor. Around the LCD screen are visible cooling vents, which increases its video recording capabilities, making this an excellent choice for video shooters requiring an ergonomic solution or those who enjoyed their Canon EOS R5s. It features 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 uses a completely new Canon-designed 45MP Full-Frame Stacked BSI CMOS Sensor with in-body image stabilization. The camera's Dual Pixel autofocus system uses 1053 autofocus points across the entire frame. It is also capable of recording 8K 60 Raw/4K 60 SRAW/4K 120 10-bit Video

The Canon EOS R5II can also use the large EF-mount lens lineup via three optional adapters, a simple EF to R adapter, one that supports the customizable control ring and another that features a drop-in filter mount.

The Nauticam NA-R5II Underwater Housing for the Canon EOS R5II Camera

The NA-R5II underwater housing follows suit with Nauticam's drive for innovation. The Canon EOS R5II 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-R5II 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 R5II 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 DSLR. As the RF lens lineup emerges, 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 simplify lens removal through the port opening.

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-R5II, 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 "Q" buttons while the sub-lever corresponds to the "M-Fn" and "Record" buttons. Near the left handle is a thumb lever for "Playback" and a dedicated switch to change from LCD to 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 additional control wheel is located on the left side of the housing. It will interface with the control ring on the supported EF to EOS R Mount Adapter with the Control Ring using the optional gear (PN 19561).

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-R5 as standard equipment. Combined with an accessory vacuum valve, this monitoring system provides constant updates on the housing's watertight and safe-to-dive status. 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 an audible and visual indication will occur if there is water intrusion.

The Nauticam system is temperature-compensated, eliminating false alarms caused by a change in outside temperature or from a camera heating up during an action-packed dive.
