The Marshall V-PL450/CS22 is a wide angle pinhole lens with a CS-mount for covert surveillance applications. With its wide 45mm focal length, the lens renders a 6° horizontal angle of view. The f/8 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-PL450/CS22 can also be mounted on the Marshall 12mm micro mount cameras.
