The Marshall V-ZPL-12MZ is a CS-mount pinhole lens with motorized zoom function to accomodate changing conditions at any given time. With a 1/3" CCD camera the lens will display a 60° horizontal angle-of-view at full wide. At the other end of the spectrum, 20mm will show a narrow 13° horizontal angle. Aperture changes with focal length. At the maximum 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.
- Electronically Variable Focal Length
- The Marshall V-ZPL-12MZ is the motorized 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 automatically operated. There is a manual version of this lens called the V-ZPL-12. Either lens may be used with Marshall's remote pan-and-tilt system components.
