Abstract: The present disclosure is directed to a lens cap with an integrated iris that screws onto a camera lens. Once secured on a camera lens, the iris may be opened by rotating an outer edge of the lens cap in a first direction. When in an open position, the entire surface of the camera lens is free from obstruction and photos may be taken as if the lens cap were not even there. The iris can literally disappear within an edge of circular lens cap. By rotating the lens cap in an opposite direction, the lens may be completely covered by the integrated iris again. For example, the iris may be opened by rotating the lens cap in a clockwise direction and then closed again by rotating the lens cap in a counter clockwise direction. Once installed, this lens cap never has to be removed.
