This optional dome port allows use of the Olympus WCON-07C Wide Conversion Lens, or it can be used with just the standard lens for increased coverage underwater.

The design mounts the lens in the port without using the Olympus CLA7 conversion lens adapter tube. This allows the camera to be removed and installed freely in the housing without removing the wide angle lens.

The back portion of the port body is screwed onto the housing, the WCON-07C lens is placed in the port body, then the dome lens front and shade assembly pushes into place.

"O" rings provide dependable sealing of the assembly, and removal of the lens when desired is simple and quick.

A dome is incorporated into the design to maintain the angle of coverage underwater for this lens, and to provide maximum possible sharpness.

Test photos below, using only one DS-50 with diffuser, show the results of this superb lens combination.

Tests by Dave Knight (Cameras Underwater Ltd UK) indicate the dome port increases angle of coverage from 56 degrees for the standard lens and flat port to 78 degrees. Installing the Olympus WCON-07C Wide Conversion Lens in the dome port yields over 94 degrees coverage.
