The Marshall V-PL300/CS12 is a wide angle pinhole lens with a CS-mount for covert surveillance applications. With its wide 30mm focal length, the lens renders a 9° horizontal angle of view. The f/11 aperture allows for excellent deep field focus. It can capture images through a tiny 1/10-inch hole in a wall or ceiling. In addition to a CS-mount the V-PL300/CS12 can also be mounted on the Marshall 12mm micro mount cameras.
