Tamron SP 15-30mm f/2.8 Di VC USD G2 Lens for Canon EF

Covering a versatile range of ultra wide-angle focal lengths, the Canon EF-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. 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. Ultra-wide zoom is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 24-48mm equivalent focal length range. Bright f/2.8 constant maximum aperture affords consistent brightness throughout the zoom range, and benefits working in difficult lighting conditions. Three LD (low dispersion) elements are featured in the optical design to noticeably limit color fringing and chromatic aberrations for improved clarity and color fidelity. Two glass-molded aspherical elements and one XGM (eXpanded Glass Molded Aspherical) element help to reduce spherical aberrations and distortion throughout the zoom range to deliver notable sharpness and accurate rendering.
