20130188941 | UNDERWATER CAMERA HOUSING - Disclosed is an underwater camera housing capable of receiving and holding a camera having an electronic viewfinder and a proximity sensor. The housing carries an element to optionally allow or substantially prevent the operation of the proximity sensor. In one embodiment the mechanism to optionally allow or substantially prevent the operation of the proximity sensor includes a material substantially non-reflective to electromagnetic waves emitted for receipt by the proximity sensor. In a second embodiment the mechanism to optionally allow or substantially prevent the operation of the proximity sensor includes a substantially reflective device able to reflect sufficient electromagnetic waves emitted for receipt by the proximity sensor away from the proximity sensor so as to substantially prevent operation of the proximity sensor. | 07-25-2013 |

20100232780 | POSITIONING DEVICE FOR A REFERENCE SURFACE - The invention resides in a positioning device for a reference surface within a lens port having a longitudinal axis. A reference surface element able to be extended substantially transversely across the port and withdrawn from the extended position are provided. A transverse movement element to effect such extension and withdrawal of the reference surface are provided and the transverse movement element is operable from a position external of the lens port. The invention also includes a camera or camera housing with a reference element of this type associated therewith. The invention finds particular use in the field of underwater photography. | 09-16-2010 |

20130343736 | MULTI-DIRECTIONAL PAD FOR AN UNDERWATER CAMERA HOUSING - The invention comprises an underwater camera housing having a body and handles on the body. The body also carries a pad positioned on the body so that the pad is accessible for use by a user substantially without the user being required to remove a hand from the most adjacent handle. The pad is able to be pressed at any point of its periphery and links mounted on the body between the pad and, in use, a position adjacent the controls of a camera are such that by pressing the pad the camera controls can be operated. The links comprise a compound lever system which in use extend between the pad and the multi selector of the camera when positioned within the housing. | 12-26-2013 |
20150124341 | MACRO CONVERSION LENS - Disclosed is a conversion lens including a sequential assembly of lens elements. The first lens element has a positive refractive power, the second lens element and the third lens element, the second and third lens elements each having a surface convex with respect to the first lens element. The characteristics of at least one lens element are selected to compensate for the use of the conversion lens in water. Desirably the first lens element includes a first part having a negative meniscus lens and a second part forming a bi-convex lens. | 05-07-2015 |
