Abstract
A lens storage container in combination with a lens support structure in which a pair of lens hold members carrying a lens cover for each lens is independently pivotal upon a support frame, and a latch structure is provided for each of the holder members. The location of the latch structure above the lens enclosure prevents gravity action from pulling the lens downwardly into the path of the latch structure and these events any lens damage therefrom.
