FIELD: photo-engineering, possible use for quick replacement of light filters with simultaneous prevention of foreign light rays from getting into objective.
SUBSTANCE: device has body made in form of truncated multi-side pyramid, in the top of which ring with thread is held for connecting device to objective of camera. Each one of light filters is positioned on appropriate facet of inner surface of body and is held on the axis, on which a spring is present, connected to lever and holding plate for fast transfer of light filters from held position to working position and vice versa.
EFFECT: possible receipt of photo-shots under conditions of fast changes of lighting and weather, increased speed of operation due to significant decrease of time needed for selection of light filters, improved cleanness and safety of light filters.
