This ultra-wide zoom lens is especially well suited for use with EOS digital SLR cameras, which usually have an imaging sensor size smaller than the 35mm format and like all of the Canon "L" lenses, delivers optical performance equal to similar fixed focal length lenses, with silent, high-speed focusing.
Distortions and aberrations are remarkably small for a lens of such amazing capability due to its Super UD (ultra-low dispersion) glass element which minimizes the chromatic aberration of magnification which tends to occur with wide-angle lenses, to help eliminate color bleed along the edges of the subject and achieve high image contrast and resolution.
Rental Package Includes: Lens, front & rear body caps and lens hood
