Nauticam Alexa Mini

Underwater Housing

Arri Alexa is the undisputed king of the feature film and commercial production video worlds, and the latest form factor iteration brings the amazing Alexa image quality into a super-lightweight carbon body that is less than half the length of an Alexa XT, and weighs 2.3 kg / 5 lbs.  Alexa Mini is ideal for use on drones, gimbals, and integrates perfectly into the Nauticam Cinema System. The 4:3 Alexa sensor, complete with anamorphic de-squeeze, ArriRAW, and ProRes recording in camera to CFast 2.0 cards in an underwater system. Footage that cuts seamlessly with other Alexa cameras on set, with the same workflow.

This housing has been produced in collaboration with HydroFlex, the world's leading underwater cinema equipment rental house, owned by Pete Romano, ASC.  Pete has over 30 years experience designing underwater housings for motion picture cameras, and numerous credits as Underwater Director of Photography from some of Hollywood's most memorable feature films.  Pete's expertise, combined with the unmatched Nauticam design and manufacturing capability, form the perfect underwater housing system for Alexa Mini. 

Easy Camera Prep


Designed with both owner/operator and rental markets in mind, the Nauticam system is very easy to build.  Armed with only a coin and #3 allen wrench, the entire support and lens control system is constructed on the camera base plate outside of the housing.  This means the rig can be built on a table, in good light, with plenty of working space.  Once the camera is assembled on its tray, the entire system slides into the housing, and locks securely in place.

Universal Lens Controls

Lens swaps are easily accomplished with the camera out of the housing, or from the port opening when the camera is installed.

The lens gearing system is universal, sliding forward or back to match lens control ring placement, and swinging down to positively engage.  No tools are required, with thumb screws securely locking all adjustments in place.

A "C" Shaped support ring is used with very long zoom lenses, providing structural support that allows precise control.

A tremendous range of lenses is supported, from very small Zeiss Standard Speeds, to very large cinema styled zooms.  Our port system has been tested with Arri UWZ 9.5-18, the most sophisticated wide angle lens ever produced, with excellent results.

Less Time Prepping, More Time Shooting

Especially with the rental market in mind, the system comes out of a travel case, and is ready to shoot in a matter of minutes.

The three housing handles slide into dovetail grooves, and are securely locked in place with cam levers.  These handles can be adjusted in water to fine tune ergonomics and control access.


Cinema Focus, Iris, and Zoom Knobs

Large diameter rubberized lens control knobs with marking disks provide the operator precise control over the lens, and are placed at the handles for ergonomic operation.

Optically Coated Glass Dome Port

Our exclusive 250mm optically coated glass dome port is supplied with every system, and we believe it is the best optic available for cinema lenses.

The 250mm dome port diameter - 10 inches - is a key for good wide angle imaging performance with many cinema lenses underwater.  Smaller domes can work well with close focusing SLR lenses, but many cinema lenses have a longer minimum focus distance in the .35-.40m (14-16") range.  Using Arri Master Prime T1.4/14mm, with its .4m MFD as an example, the 250mm dome provides clearly superior results, with much less corner softness than smaller domes.  This is the very same dome used in the optical system designed in conjunction with HydroFlex for Alexa65, and used on feature film productions.

The glass dome is rugged, and extremely resistant to scratching.  Broadband Anti-Reflective Coatings eliminate flare, reflections, and ghosting from the port optic. A robust machined aluminum shade protects the dome, and provides additional flare resistance.


Patented Port Locking System

One of the most iconic Nauticam features is the red Port Locking Lever.  This system uses an internal bayonet, allowing ports to mount directly on the housing, then lock securely in place.  No twisting is required, just press in and lock!  This simplifies lens changes, and actually reduces the chance of an extruded o-ring causing a leak. 

Designed for Tethered Shooting or Single Operator Use

The base system completely satisfies the needs of a single operator configuration, but our lineup of accessories geared toward production sets makes the Nauticam housing as at home on a feature film set as it is on a coral reef.  The housing contains enough internal space for internally mounting the Arri cforce Mini Motors.  These motors drive the housing lens controls, not the lens itself, meaning any lens supported the housing can be set up for surface control of Focus, Iris, and Zoom.  Alexa Mini features a built in motor controller, allowing the system to be set up without any motor controller box!

Our 4-pin 


Sliding Trim Weight Bracket

A trim weight bracket, built to accept readily available dive weights, slides forward and back on a dovetail on the housing bottom.  This allows the housing trim to be adjusted dynamically in water.  Smaller bolt on trim weights are included, and can be attached to mounting points inside the housing, or on the housing skids, to dial in precise left / right balance as needed.
