Canon EOS M50 Underwater Housing by Nauticam

The Canon EOS M50 II Camera

For the underwater shooter looking to move into an interchangeable lens camera system with a large APS-C sensor, the 24MP Canon EOS M50 Mark II is a feature-rich yet budget friendly option.  Adding enhanced Dual Pixel Autofocus with both eye and face detection, 4K/24p UHD video (with a 1.5x crop) and a built-in EVF the EOS M50 Mark II sits between the EOS M200 and M6 Mark II.  The M50 Mark II also allows for the capture of images in Canon's CR3 RAW format that allows for full-resolution compressed RAW capture.

The NA-EOSM50II Underwater Housing

Nauticam is the industry leader in mirrorless interchangeable lens underwater camera support. Nauticam has housed more mirrorless cameras than any other housing manufacturer. This experience results in the most evolved housing line with the broadest range of accessories available today.

Pioneering optical accessories elevate performance to a new level. Magnifying viewfinders, the sharpest super macro accessory lenses ever made, and now the highest quality wet mount wide angle lenses (the WWL-1 and WWL-C) combine with the NA-EOSM50II housing to form a complete imaging system.

Nauticam is known for ergonomics, and an unmatched experience. Key controls are placed at the photographer’s fingertips. The housing and accessories are light weight, and easy to assemble. 

NA-EOSM50II underwater housing features an integrated handle system that provides exceptional control access, even with thick gloves, and ideal placement of the shutter release and critical function buttons at the right handle.

Nauticam build quality is well known by underwater photographers around the globe. The housing is machined from a solid block of aluminum, then hard anodized making it impervious to salt water corrosion. Marine grade stainless and plastic parts complete the housing, and it is backed by a two year warranty against manufacturing defects. 

WWL-C Compatibility

Designed by founder and Managing Director Edward Lai, the WWL-C is the perfect lens to complete an EOS M50 Mark II underwater system. The magic of the wet lenses is their tremendous versatility, paired with outstanding in-water performance. Both macro (CMC-1/2) and super wide angle optics (WWL-1/C) are available to the underwater photographer on the same dive. These lenses are completely engineered for use in water, providing the highest image quality available today in a wet mount optic.

WWL-C is a wide angle conversion lens, compatible with several lenses in the Canon EF-M system. Paired with the 15-45mm f/3.5-5.6 IS STM the WWL-C allows the zoom range from 17mm to 45mm to be used. This combination provides class leading center sharpness, corner sharpness, and contrast which results in the clearest wide angle images possible underwater.

Flash Connectors for INON S-TTL, Sea&Sea DS-TTL

Reliable automatic flash exposure is available with the NA-EOSM50II and a variety of optically fired flashes. The Inon Z-330, Z-240, D-2000, S-2000, and Sea & Sea YS-YS-D2J/D3 strobes provide automated lighting, precisely reproducing the camera’s onboard flash at a proportionally greater intensity. This system yields accurate automatic TTL flash performance – even in manual mode – with no electrical sync cables to flood! The NA-EOSM50II comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Nauticam Fiber Optic cables, compatible with both Inon and Sea & Sea strobes, provide the best light transmission and therefore more accurate TTL of any fiber optic cable on the market.

Strobes and light arms can be attached to the housing via included 1″ accessory mounting balls.

Electrical strobe triggering (with power set manually on the flash head) is still an option for those with an investment in legacy lighting gear, requiring the purchase of an accessory electrical bulkhead.

Integrated vacuum check and leak detection system

The Nauticam vacuum check and leak detection system is available with NA-EOSM50II as standard equipment. Combined with an optional M14 Vacuum Valve II (PN 25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple 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.
