Nauticam Shipping Housing for Canon EOS C500 Mark II/C300 Mark III
By Ian Bongso-Seldrup, January 5, 2021 @ 06:00 PM (EST)

Nauticam is now shipping its new Canon cinema camera housing compatible with both the EOS C500 Mark II and EOS C300 Mark III, which share the same body design but feature very different sensors. The latter has a 9.6MP Super 35 sensor that records 4K DCI/UHD at up to 120fps, while the former can shoot up to 5.9K/60p using its 20.8MP full-frame sensor.

Built around the same N120 port system as Nauticam’s housing for the Canon EOS C200 Cinema Camera, the NA-C500II takes the company’s “Mission Control” concept even further by positioning various electronic control functions at the user’s fingertips, features large control knobs for focus and zoom, and comes with Nauticam’s vacuum check and leak detection system as standard. Optional HDMI/SDI bulkheads support a surface monitor feed or an external monitor, or a dedicated monitor (Canon LM-V2) can optionally be mounted in the rear of the housing.

Available now, the new housing is priced at $10,860.

The Nauticam C500II Underwater Housing is compatible with both the Canon EOS-C500 Mark II and EOS-C300 Mark III Cameras. While each camera has its own unique specifications, there are a couple shared sticking points that underwater video shooters have to come to love with a Canon cinema camera, autofocus and white balance. “Canon Color” or Canon’s unique ability to give better manual white balance results than any other camera manufacturer and Canon's Dual Pixel AF which uses two photodiodes behind each pixel to improve the camera's autofocus abilities are precisely why Canon cameras remain so popular underwater.

Both cameras also share the unique ability to record in Canon RAW Light format that captures Raw video data in files as little as 1/5 the size of standard Cinema RAW files.


Nauticam has long been producing industry-leading housings for Cinema cameras and have taken that experience to create the most advanced underwater cinema system housing available.

Taking advantage of the small form factor of the C500 Mark II and the C300 Mark III, the Nauticam NA-C500II is ultra-portable yet offers full access to the camera’s critical functions. Nauticam has taken a modular approach to the this system, similar to that of the DCS housings for RED and ARRI cameras with a wide variety of add-ons from top-handles to skids and movable trim weights.

The NA-C500II features multiple bulkhead openings for HDMI/SDI Bulkheads to support an external monitor or surface monitor feed. The housing also supports the Canon LM-V2 4.3" LCD monitor in the rear of the housing for a more streamlined approach.

The housing includes the newest version of the venerable Nauticam Cinema Skids that feature tracks along which the optional trim weights can be moved to achieve perfect trim for the shot. Mounts on the housing itself also allow for direct attachment of the trim weights to allow for either a fixed trim or for when using tripod legs instead of the skids.

The housing will accommodate the Canon BP-A30 and larger BP-A60 batteries, providing plenty of run time. As with previous Cinema System housings, the Nauticam NA-C500II features large control knobs for focus and zoom which also feature marking disks that can be removed and marked with the desired lens position or focus information.


Regardless of where a button or control dial may lie on the camera body, Nauticam engineers obsess over making sure that access to that control on the housing be intuitively placed for ease of use to insure no shot is missed while searching for a button or dial. To take this a step further, Nauticam has also integrated the Nauticam to Canon SDK Control Board which places a variety of electronic control functions at your finger tips.


The Nauticam vacuum check and leak detection system is shipped with NA-C500II as standard equipment. Also included is the 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.


Optical performance is just as necessary as camera performance and this becomes even more critical given the challenges of filming underwater. The Nauticam NA-C500II uses the same N120 Port System as the previous NA-C200 housing which makes for a seamless transition for those upgrading to the C500 Mark II or C300 Mark III. While this system provides exceptional optical-glass and flat port solutions for a wide variety of EF-mount lenses, the real power can be realized using Nauticam's Water Contact Optics. This lineup of dry and wet lenses are conceived using commercial lens-design software to achieve truly unparalleled underwater image quality both for stills and video in both macro and wide-angle situations. The WACP-1 and WACP-2 achieve ultra-wide 130º fields-of-view with reduced distortion over conventional optics while featuring ~0" minimum focus distances, zoom through capabilities and unbeatable corner sharpness at even wide-open apertures such as F5.6. The SMC-1 and SMC-2 macro wet-optics, when used with the Canon 100mm F2.8 macro lens provide 2x and 4x magnification respectively and the SMC-1 actually provides a resulting image with increased contrast and sharpness than the 100mm lens itself can achieve in air without a magnifier.




Taking your eyes off the monitor to adjust a setting means potentially missing the shot. The Mission Control philosophy of Nauticam Housings means that all essential exposure controls are placed within easy reach from the handles. To take this a step further, Nauticam has integrated the Nauticam to Canon SDK Control Board to place critical controls at your finger tips.



Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.



The NA-C500II features oversized mechanical zoom and focus knobs with erasable surfaces for focus/zoom position marks. The internal gearing is moved away quickly via a small external lever to allow removal of the camera without disruption of focus/zoom gear alignment.




The NA-C500II features a variety of mounting points for accessories such as top handles, cheese-plates, mounting balls, bulkheads and more. Six M16 Bulkheads allow for situation-specific arrangement of cables and accessories.




Connect the NA-C500II to an external monitor or surface support with an HDMI or SDI bulkhead. The C500 Mark II and C300 Mark III feature SDI and HDMI output.
