Superb corner-to-corner image quality from an ultra-wide-angle zoom
The new 15-30mm F/2.8 full-frame ultra-wide-angle zoom is a worthy addition to the Tamron SP (Super Performance) lens series, renowned for its highest standards. Thanks to the development of its unique XGM (eXpanded Glass Molded Aspherical) element, the high-performance zoom lens offers the same performance as would two fixed focal length lenses of 15mm and 30mm.
The unique XGM element responsible for this unprecedented achievement effectively controls aberrations and enhances sharpness.
Features and Functions
Fluorine coated front element: Because the large diameter and prominent convex profile of the front element does not allow the use of a protective filter, the front element of the lens has a fluorine coating. The coating repels water and dirt, and also makes it much easier to remove smudges.
