Focal length 11-20mm that covers equivalent angle of 42.9mm-78mm (Chronos 1.4) and 22-40mm (Chronos 2.1-HD) lenses makes this lens attractive to be chosen after standard zoom lens or initially possessed wide angle zoom kit lens.
A constant maximum aperture of f/2.8 throughout the entire zoom range is realized to achieve great results in low light conditions, for depth of field control and easy manual shooting, while maintaining a reasonable size and weight. Includes 2-year manufacturers warranty.
Note: The Nikon F-C adapter with iris control is required or else the lens will default to F22 if the iris pin is not engaged. User will not be able to adjust the iris in this case.
