Isotta Olympus OM-D E-M5 Mark III Underwater Housing

UWI-3180 | EM5-MIII


The Isotta Olympus OM-D E-M5 Mark III Underwater Housing (without handles) allows you to capitalise on the full potential of the Olympus OM-D E-M5 Mark III Mirrorless Camera and to capture amazing pictures underwater. It's an easy to use, highly professional product that has been created through techniques and innovations gained from years of experience. Easy access to all key/main Olympus OM-D E-M5 Mark III mirrorless camera controls by means of clearly labelled laser-engraved long-lasting buttons. The back door has a large window for a fine camera display view and it is entirely detached from the front body to make for easier camera fitting. The housing stands with great stability due to sturdy and wide rubber feet located on the bottom.

Flash triggering
This housing ships with two optical bulkheads installed as standard equipment.

One Hand Open/Close
It's very easy to open and close the Olympus OM-D E-M5 Mark III underwater housing, without any effort by the user thanks to the side helicoid screw and the bottom centred pins. The camera is placed easily into the housing on a sliding tray that keeps the camera robustly in place.

Ports and Extension Ring
A series of ports and extension rings are available. The removable port is fitted thanks to markers and a bayonet 102 mm connection to the Olympus OM-D E-M5 Mark III housing. The interchangeable port bodies and extensions rings combine to allow the use of most of the lenses on the market for maximum versatility and performance.

Two fibre optic connections are placed in front of the built-in flash and allow the use of an external strobe.

Construction and Safety
Only the best materials are used to manufacture Isotta housings such as anodised aluminium, which is anticorodal and thermo-coated, and stainless steel. A long-lasting product that requires easy and simple maintenance by the user. So small and so rich in technology! Dual high precision and quality O-ring seals protect and ensure a perfect and secure watertight for all movable and/or removable parts. A red alarm for humidity/water inside the housing is powered by a battery replaceable by the user. The working depth is 100 metres. Different accessories can be fitted directly on the handles or by means of an M8 upper threaded hole, using the Isotta top handle or via the M6 and M8 threaded holes on the bottom.
