The wonder material Carbon

What could be more obvious than constructing an underwater housing out of this material
for capturing the diversity of underwater life in picture and sound !?

Our special underwater housings are made of high strength carbon fibres. Carbon fibres consist of atomic carbon chains which are spun into yarn and then woven into a fabric. The resultant material is known colloquially as carbon fibre. It occurs as soft, layered graphite sheet form in pencils and in incredibly hard crystalline form in diamonds in nature. It is present in sugar, and is also commonly encountered as fine soot, which in combination with water forms the basis of organic life on our planet.

Nowadays, more and more often, highly stressed parts are manufactured from carbon fibre. Its main application is in the areas of aviation, aerospace, motor sports, sports equipment, and wherever lightweight items capable of withstanding extremely high stress are required.

The carbon fibre is capable of withstanding mechanical stress from strain, compression and bending. Epoxy resin is used to mould carbon fibre. It binds to the carbon-fibre fabric and gives it its shape.

It is the carbon fibre which gives the underwater housings from BS Kinetics mechanical properties similar to those of steel, whilst still retaining the advantages of plastic polymers. The composite material is corrosion resistant and chemical resistant and has anti-weathering and anti-aging properties. It is very lightweight, which offer a distinct advantage, particularly when flying, given baggage constraints.

By using multiple layers of carbon fibre, housings used by technical divers can be built, which are depth rated up to 160 m despite the much reduced thickness of material.

Carbon fibre allows BS Kinetics to produce housings that are lightweight, yet manage to defy all the odds involved in diving. All other plastic components of the underwater housings are made of POM. This high-quality plastic has excellent technical properties and guarantees components long life. V4A, another marine grade material resistant to salt water, is used to make the operating controls.

Operating controls

Whether video- or photohousings – Full control at any time

Underwater photo housings

Camera controls use Reed contacts in the underwater video housings. Reed contacts obviated the necessity for bushes in the housing, which resulted in the minimal use of O-rings.

Specially developed controls are used for cameras with a LANC port. Nowadays menu control is also possible, as is white balance control for certain cameras.

With other cameras, which don´t have a LANC, the infrared remote control is used.

Underwater video housings

The operating controls benefit from a double O-ring sealing arrangement and are therefore made a safe as possible. The seals are maintenance-free, but must be replaced after several years of use.

Ergonomics is of utmost importance to BS Kinetics in their underwater housing. For this reason, the shutter, focus and AV button can all be operated using the right hand without letting go of the casing.

The desired image is selected using the zoom, which is operated with the left hand. All other operations are carried out using buttons or triggers on the back or top of the housing.

Mounting

Positioning the camera in the waterproof housing is very easy. The camera is bolted to the housing table and connected via hot shoe or LANC port. In case of bigger sized housings the camera is mounted on a slide and slid into the case.

Sealing

The underwater housing unit is sealed with a high quality O-ring made of silicone. The use of special notch geometry makes them simple to insert and they do not have to be greased. Their 3.5 mm diameter ensures very simple handling and maintenance.

Closures

The underwater housing is closed by means of quick release latches. These quick releases are made of marine grade stainless steel. They allow for fast opening and closing of the housing and guard against accidental opening.

360° Shutter release lever

To ensure the optimal usability of our underwater housings, the shutter release can be adjusted steplessly and so on individually for the photographer.

Therefore just pull the lever away from the housing and turn it to the desired position. After adjusting the desired position the shutter release lever engages the catch.

Flat- and Domeports

BS Kinetics offers a wide range of flat and dome ports for the underwater housing. The ports are made of POM and connected by bayonet screws to the underwater housing. Silicone O-rings are also used to seal the ports.

Some underwater video housing have a fixed inbuilt converter port, which has a M67 thread, making adaptation of macro or wide angle lenses possible under water.

Viewfinders and monitors

In the photo underwater housings, looking at the camera viewfinder is achieved by using the optical viewfinder on the housing. This reduces the camera viewfinder image, although it allows an almost complete visibility on the housing viewfinder.

With underwater video housings a view can be taken directly from the digital 3,6″ 16:9 monitor. The monitor is powered by an internal rechargeable battery. The battery level is indicator is permanently displayed.
