Superb corner-to-corner image quality from an ultra-wide-angle zoom. Lens will come in the orignal box in factory min condition. This is the US version

Tamron aims for the highest standards with the SP (Super Performance) lens series. And the new 15-30mm F/2.8 full-frame ultra-wide-angle zoom is a worthy addition. This high-performance zoom lens equals the performance of fixed focal length lenses from 15mm to 30mm, an unprecedented achievement made possible by the development of its unique XGM (eXpanded Glass Molded Aspherical) lens element that effectively controls aberrations and enhances sharpness. In addition, the 15-30mm is the first zoom to combine such a wide range of coverage, a fast F/2.8 aperture, and to offer image stabilization, further proof of Tamron's commitment to innovation and excellence.

XGM lens element for exquisite images -- A large diameter XGM (eXpanded Glass Molded Aspherical) lens element is placed in the first lens group of a system that also includes several LD (Low Dispersion) elements in its 18-element, 13-group optical design. This combination effectively controls distortion and chromatic aberrations that typically affect wide-angle lenses.
