Covering a versatile range of ultra wide-angle focal lengths, the Nikon F-mount SP 15-30mm f/2.8 Di VC USD G2 from Tamron enhances this wide zoom with sophisticated optics, focusing, and image stabilization. Helping to realize sharp, clear imagery, the optical design incorporates aspherical and low dispersion glass elements to reduce both spherical and chromatic aberrations throughout the zoom range. A trio of coatings AX, eBAND, and BBAR have also been applied to suppress lens flare and ghosting for improved contrast and color rendering when working in bright and backlit conditions.
