Standard zoom is designed for FX-format F-mount cameras, however can also be used with DX models where it provides a 36-105mm equivalent focal length range.
Bright constant f/2.8 maximum aperture affords consistent illumination throughout the zoom range and also affords greater control over depth of field for isolating subjects and working with selective focus techniques.
Three aspherical elements are used to reduce spherical aberrations and distortion in order to realize sharp imagery with accurate rendering.
Three extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color accuracy.
Both a Nano Crystal Coat and a Super Integrated Coating have been applied to individual elements to suppress internal reflections, flare, and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override. An internal focusing design is also used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.
Rounded nine-blade diaphragm promotes a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
