Marshall Electronics CV 2812 3MP

The CV-2812-3MP is a varifocal M12-mount lens for Marshall's compact and POV cameras that use screw-in board lenses, matched to a 3-megapixel 1/2.7-inch sensor. Its 2.8 to 12mm focal range spans a wide 109-degree view at the short end down to about 31 degrees zoomed in, so one lens can cover anything from a wide room shot to a tighter angle without changing hardware.

The F1.4 aperture is fixed, while focus and zoom are set by hand and held with lock screws once framed. An IR-cut coating on the rear element keeps infrared light from washing out the image under mixed or low lighting, and the M12 thread mounts directly to cameras like the CV504 mini POV.
