The Marshall V-ZPL-12 is a CS-mount pinhole lens with manual zoom function for changing conditions or location. With a 1/3" CCD camera the lens at full wide will display a 60° horizontal angle of view. At the other end of the spectrum, 20mm will show a narrow 13° horizontal angle. Aperture changes with focal length. At the maximum zoom 20mm the lens has a f/12.5 aperture (f-stop=focal length/1.6). The lens is made for tough industrial environments. A push-on front cap has two functions. It has a clear tip to protect the lens' front element. The cap also has a mounting support.
Manual Vari-Focal Lens
The Marshall V-ZPL-12 is the manual version of this 4-20 mm industrial lens. The aperture is tied to the focal length so the f/ stop is also going to be manually controlled. There is a motorized version of this lens called the V-ZPL-12MZ. Either lens may be used with Marshall's remote pan-and-tilt system components.
