The Marshall V-ZPL-1050 is a CS-mount pinhole lens with a manual zooming function for changing conditions or locations. With a 1/3" CCD camera the lens will display a 28° horizontal angle-of-view. At the other end of the spectrum, 50mm will show a narrow 5.5° horizontal angle. Aperture changes with focal length. At the maximum 50 mm the lens has a f/31 aperture (f-stop=focal length/1.6) so this is not a low-light lens at zoom range. But 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 integrates a mounting support.

The Marshall V-ZPL-1050 is the manual version of this 10-50 mm industrial lens. The aperture is tied to the focal length so the f/ stop is also going to be manually operated. There is a motorized version of this lens called the V-ZPL1050-MZ. Either lens may be used with Marshall's remote pan-and-tilt system components.

Q: 1. Is this lens compatible with Canon T4i? if not, would Rokinon have any other 12mm 2.0 compatible with this camera?

A: No, only EF or EF-S lenses will work on a Canon T4i. Two similar lens options would be the Rokinon 12mm f/2.8 ED AS IF NCS UMC Fisheye Lens for Canon EF Mount or the Rokinon 14mm Ultra Wide-Angle f/2.8 IF ED UMC Lens For Canon. These are a bit slower at f/2.8 but, these are your only options if you want that focal length. Next widest focal length, for lenses faster than f/2.8, would be 24mm. At that focal length you have to choose from Canon, Sigma or Rokinon lenses.
