Canon R6 III Underwater Housing

The Canon R6 Mark III underwater housing marks the next exciting step for full-frame mirrorless shooters looking to capture stunning stills and video beneath the surface. Building on the strong foundation of the Canon R6 Mark II, which proved to be an outstanding performer underwater, the new R6 Mark III brings even more power, resolution, and creative flexibility to underwater photographers and videographers alike.

The Canon R6 Mark II quickly earned its place as a favorite among underwater shooters, praised for its fast autofocus, robust in-body image stabilization, and high-quality 4K video capabilities. In the R6 Mark II underwater housing guide, a wide range of durable and ergonomic housings—from brands like Ikelite and Nauticam—helped divers get the most from this hybrid camera while underwater. 

Canon’s new R6 Mark III brings meaningful advancements that are sure to translate beautifully beneath the surface. Featuring a new 32.5MP full-frame sensor (up from 24.2MP in the R6 II), the camera delivers sharper details and greater cropping flexibility—ideal for wide reef scenes or close-focus macro compositions. The R6 Mark III also improves burst shooting (up to 40fps electronic) and introduces enhanced 7K RAW-light recording and 4K at up to 120fps, offering underwater videographers incredible creative range and smooth slow-motion capability.

Autofocus, image stabilization, and processing have all been refined as well, meaning even better performance in low light and dynamic underwater environments. Given how well the R6 Mark II handled underwater autofocus tracking and color reproduction, these improvements promise even stronger results for both stills and video.

While official housings for the R6 Mark III have yet to be announced, it’s highly likely that leading brands such as Ikelite, Marelux and Nauticam will offer dedicated Canon R6 Mark III underwater housings soon. Both manufacturers have a proven track record of supporting Canon’s mirrorless lineup—particularly the R6 Mark II—with durable, ergonomically designed housings optimized for underwater use. We expect:

• Ikelite to release a polycarbonate housing, offering affordability, durability, and excellent ergonomics.

• Marelux to follow with their durable polished aluminum housing.

• Nauticam to follow with a high-end aluminum housing featuring advanced control access, vacuum sealing systems, and full port compatibility for Canon RF lenses.

These housings will enable underwater photographers to take full advantage of the R6 Mark III’s next-generation capabilities—whether shooting wide-angle reefscapes, fast-moving marine life, or cinematic underwater video.

The Canon EOS R6 Mark III is positioned as a highly versatile, full-frame mirrorless hybrid powerhouse—designed to serve both serious photographers and hybrid shooters who demand strong stills and video performance in one body. With this model, Canon continues to refine and elevate its “R6” line: offering improved resolution, enhanced autofocus, upgraded video capabilities, stronger image stabilization, and modern media interfaces—all while retaining the familiar ergonomics and RF-mount system that users of the R6 family appreciate.

Photographers get a camera that addresses more advanced workflows: higher pixel count gives more flexibility for cropping and large-print output; improved subject tracking and AF intelligence aid fast action, wildlife or event work; and video creators benefit from higher resolution, expanded frame rates and better codec/format options. At its core, the R6 III aims to deliver a one-body solution for a wide range of content creators—from wedding photographers to documentary filmmakers to hybrid shooters—without stepping into the ultra-high-end price zone.

The body retains a well-regarded build, comfortable handling, and the RF-lens ecosystem (which already includes top-class optics). But importantly, Canon has equipped the Mark III with next-generation features to keep pace with competitors and future demands. Whether you’re shooting stills under challenging light, chasing fast action, or filming high-quality motion for editorial or commercial use, the R6 III aims to be the “all-in” solution.
