Nauticam Unveils Housing for the Canon EOS R7
By Ian Bongso-Seldrup, August 8, 2022 @ 12:00 PM (EST)

Nauticam has announced its housing for the Canon EOS R7, the higher-spec’d—and more expensive—of two recently released RF-mount camera bodies with cropped sensors (the other being the EOS R10). The R7 features a 32.5MP APS-C sensor, shoots continuously at up to 15fps with the mechanical shutter (and up to 30fps with the e-shutter), and records UHD 4K/60p 10-bit video using the full sensor width.

Like Nauticam’s housings for other models in Canon’s mirrorless EOS line, the NA-R7 accommodates both RF lenses and EF lenses via an adapter. Controls are ergonomically arranged around integrated handles, including a right-hand dual thumb lever for M-Fn and Record as well as a right-hand single lever for AF-ON.

The housing offers built-in fiber-optic bulkheads, and fiber-optic triggering of strobes is possible via an optional manual or TTL trigger. Videographers can attach an external monitor via HDMI 1.4 or an external monitor/recorder like the Atomos Ninja V or Ninja V+ via HDMI 2.0. Nauticam’s vacuum check and leak detection system comes as standard.

Priced at $3,377, the Nauticam housing for the Canon EOS R7 can be ordered now from retailers such as Backscatter.

Introducing NA-R7


The Canon EOS R7 is the latest in Canon's APS-C mirrorless camera lineup which has gained unprecedented demand. 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 R7 uses a 32.5MP CMOS sensor with in-body image stabilization which can reduce shake by up to 7 stops. The camera's Dual Pixel II autofocus system was carried over from the pro body EOS R3 and features 651 automatic AF points covering the entire sensor area. It is also capable of recording oversampled 4K 30p video using the full 7K area of the sensor, or subsampled UHD 4K up to 60p from the full sensor width.  

The EOS R7 can also use the large EF-mount lens lineup via a simple EF to EOS R adaptor. The Nauticam NA-R7 housing only supports the the standard EF to EOS R adaptor and does give access to the control ring or drop in filter adaptors. 

Key Camera Specifications

  • 32.5MP APS-C CMOS sensor with Dual Pixel AF
  • Up to 30 fps shooting (e-shutter), 15 fps with mechanical
  • In-body image stabilization, rated at up to 7 stops
  • Oversampled UHD 4K up to 30p, line-skipped or cropped 4K/60p
  • 10-bit video as 'PQ' true HDR footage or C-Log
  • 2.36M dot OLED viewfinder
  • 1.62M dot fully-articulating touchscreen
  • Twin UHS-II SD card slot
  • Environmental sealing


The NA-R7 underwater housing follows suit with Nauticam's drive for innovation. Like the full frame Canon EOS R5, R5 C and R3, the NA-R7 present 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 designed a N100 to N120 adapter which integrates into the N120 Canon EF port system. Canon's EF to RF mount adapters can be affixed to the camera before insertion into the housing. When using the EOS R7 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-S lens lineup emerges, dedicated port and extension ring combinations will be listed on the new N100 RF-S Port Chart.

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-R7 where a dual thumb lever is placed by the right front side accessing the M-Fn and Record buttons. On the rear right side is a thumb lever accessing AF-ON. Near the left handle is a thumb lever for "Playback."

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.

Flash Triggering

Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (PN 26305) 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-R7 as standard equipment. Combined with an accessory vacuum valve (25624) 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.
