ABSTRACT:
A lightweight flexible transparent plastic enclosure is provided with a reinforced circular aperture engaging over the camera lens with the camera being enclosed within the enclosure. A screw on filter is then engaged with the lens ring and clamps the boundary of the aperture against the lens ring in sealing relationship. Alternatively, a pair of rings screw threadably engaged together and clamp the boundary of the aperture of the enclosure there between and this pair of rings is then in turn held against the lens ring by the screw threadable engagement of the filter with the lens ring. The flexible and transparent bag enables the camera to be manipulated but at the same time it is protected against adverse weather conditions such as sand, dust, salt water spray and the like.
