ewa-marine U-B100 flexible housing

The U-B 100 Housing is a modified version of the U-B housing.

It has been specially developed for use with the large professional SLR camera such as Nikon D300, D800, D3, D4 and Canon 5d Mark II, 5d Mark III, Eos 1DX in combination with light-strong lenses with 77mm and 82mm filter threads. It is equipped with a larger front window. The lenses are connected to the glass with the help of the C-A82 and RA77-82 reducing adaptor.

Even wide-angle lenses with 16mm focal length (equivalent to 35mm or full format chip) can be easily used in this housing.

The autofocus (AV110) Attachment of the U-B enclosure is not required and is also not included.

Attention: All the lenses used must have internal focus.

Smaller SLR cameras can of course also be used in the housing.
Lenses with a smaller filter thread than 77mm can be used with the help of reducing adapters as long as they have an internal focus.

The housing is made of special foil and has an integrated optical glass port.

It is ideal for snorkelling, scuba diving (up to 20m), on the beach, in the desert, in rainy weather or in areas with high humidity.

The closure of the housing consists of two clamping rails, which are screwed together with three screws, thereby sealing the housing waterproof.

Lead weights can be attached to the strap on the bottom of the case to confronting the housing.
