The Marshall V-PL200C is a C-mount pinhole lens for covert surveillance applications. With its 200 mm long focus the lens renders a narrow 2.5° horizontal angle-of-view. The f/20 aperture renders extreme depth-of-focus though sufficient light must be available. The lens is almost 11 inches long which keeps the camera significantly distanced and out of view. According to the manufacturer the lens will resolve focused images as close as about 15 inches or about 380 mm.
