Covering power of the W-series Nikkors is an ample 70-73° when stopped down. Lens construction of the series---six elements in four groups---gives these lenses an outstanding degree of freedom from distortion, field curvature and chromatic aberration. Nikon Integrated Coating assures high contrast and overall faithful color rendition. The W-series lenses are recommended for a variety of subjects, including landscapes, portraiture, architecture and table-top photography.
