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.
Benefitting the optical assets, performance and handling is enhanced through the use of dual MPUs (Micro-Processing Unit), which ensure fast and reliable image stabilization and autofocus. Vibration Compensation accounts for up to 4.5 stops of camera shake, to result in sharper images when shooting handheld at slower shutter speeds. Conversely, a USD motor provides quick and quiet autofocus performance as well as full-time manual focus override. Additionally, the lens body is weather-sealed and moisture resistant, and the front element features a protective fluorine coating to guard against dust and smearing.
