Introducing Digital Cinema System for ARRI ALEXA Mini Camera

The ARRI ALEXA Mini Camera

Rounding out the range of cinema cameras created by powerhouse ARRI, the Mini fits perfectly into underwater production by giving shooters a more compact compliment to their ARRI camera lineup. The ALEXA Mini features a carbon-fiber housing, integrated sealed electronics and both sensor and PL mounts made from titanium.

The Mini can record ProRes at 200fps or Uncompressed ARRRIRAW at 30fps to on-board CFast 2.0 memory cards. The lens mount can be changed between PL, B4 and Canon EF.

The Nauticam Digital Cinema System for ARRI ALEXA Mini

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 – available for rent at HydroFlex Partners worldwide.

The 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 captures footage that cuts seamlessly with other Alexa cameras on set, with the same workflow.

Easy Camera Prep

Designed with both owner/operator and rental markets in mind, the Nauticam system is very easy to set up. Armed with only a coin and a #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.

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.

Battery Configurations

The housing ships with an Anton Bauer “Gold Mount” battery plate and LEMO connector for the Alexa Mini camera. Ample space is available for a range of battery pack sizes to be used in the housing, providing long operation times. Surface suppled power is also an option for for tethered all day shooting.

Weight & Trim Bracket

A sliding weight bracket allows front-back trim to be adjusted dynamically in water, providing a natural port up or port down position as needed. The bracket accepts readily available dive weights, easily sourced on location. Additional trim weights can be attached to the housing skids, or to trim weight mounting locations strategically placed on the inside of the housing, to dial in neutral buoyancy and left-right balance.

Universal Lens Controls

Unencumbered surface control is a key need of many top underwater professionals, and those needs have been integrated in as many forms as possible throughout the design process. The base “diver controlled” system completely satisfies the needs of a single operator, 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 an Indo-Pacific 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! These motors are mounted on purpose built brackets affixed to the camera tray, and do not need to be removed when changing lenses, or when pulling the camera from the housing.

The housing also ships with two 3/4″ Hydroflex Bulkheads allowing the power, remote control, and remote monitor umbilical from other Hydroflex rental systems to be used on Alexa Mini.

Features

Patented Port Locking System

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.

Housing Locking Latch

The secure single rotating housing latch opens the housing back allowing for quick and easy battery or media changes.

Adjustable Handles

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.

Accessory Mounting

Numerous 1/4-20, 3/8-16, and 10mm threaded accessory mounting location are provided.  These accessory positions allow monitors, lights, tripod/jib plates, and other accessories to be placed conveniently on the housing. The housing also ships with two 3/4″ Hydroflex Bulkheads allowing the power, remote control, and remote monitor umbilical.

Universal Lens Controls

Lens swaps are easily accomplished with the camera out of the housing, or from the port opening.  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 for precise control.

Integrated Vacuum System

The Nauticam vacuum check and leak detection system is available with Alex Mini Housing as standard equipment.  Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

How do you ship my orders?

CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days.

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.
