Tamron SP AF 15-30mm F/2.8 DI USD Sony A-Mount

The Tamron SP AF 15-30mm F/2.8 DI USD is an ultra-wide-angle zoom lens designed for full-frame Sony A-mount digital SLR cameras. This pioneering lens delivers a constant F/2.8 aperture across its entire focal range, making it exceptional for low-light photography, landscape work, and creative wide-angle compositions. The sophisticated 18-element, 13-group optical design incorporates an XGM (eXpanded Glass Molded Aspherical) element and multiple LD (Low Dispersion) elements to effectively control distortion and chromatic aberrations. The front element features a fluorine coating that repels water and dirt, eliminating the need for a protective filter. With a minimum focus distance of just 28 centimetres and its fast F/2.8 aperture, the lens delivers beautiful bokeh effects even at wide angles.
