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 over smaller domes. Images have higher overall sharpness, and much higher corner sharpness with the 250mm dome. This is the very same port used in the optical system designed in conjunction with HydroFlex for Alexa65, and used in feature film work.
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.

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.                                         
- HD-SDI Cables for Surface Monitoring
- 4-Pin Waterproof LCS Cable for WCU-4 Control of 3 Motors and Camera Functions - Ethernet for Surface Camera Control
- ARRI “cForce mini" Motor Mounting Brackets
The housing also ships with two 3/4" Hydroflex Bulkheads allowing the power, remote control, and remote monitor umbilicals from other Hydroflex rental systems to be used on Alexa Mini.
Easy Camera Setup
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 the camera, lens, lens control system, and even motors 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.
Lens changes are just as easy, with accessed through the large 200mm port opening, or even more easily by pulling the camera and lens out of the housing back door for unencumbered access.

DW 435 Housing for the ARRI 435


altThe DW 435 is relatively simple and easy to use in the water. This housing was designed to work with the Arri 435 IVS with a 122m chassis. It can be mounted /assembled together with different lenses, Cooke, Panavision or Zeiss. The dome and flat port are interchangeable.

With its own lense and through the eye of the camera, the operator is able to see a large and clear image. The display port extends behind the rear of the housing to provide more space and making it possible for the camera operator to place his mask as close as possible to the viewer, allowing for a comfortable working position. Both the focus and the iris controls of the lens are to be found in the front left of the housing and can be easily viewed and adjusted by the operator or the assistant.
We have incorporated a witness camera near to the lens and an 2.5” external monitor so enabling the assistant to see the marks of the lens from the outside. There is also a direct view of the meter counter from a side window and from another window the display indictions can be seen.
Two Anton Bahuer lithium batteries provide power to the camera and can shoot multiple chassis unchanged.
NOTE:  The 435 Extreme does not work with the radio module FEM 2.

Like many Nauticam housings, the play button is brought up to the left thumb, and the three command dials (think shutter speed, aperture and exposure compensation) can be adjusted quickly with minimal reach. The ISO button is within short reach of the right thumb, important for video shooters. Speaking of video, the record button is on the top right, thus eliminating camera shake during video start/stop.
