The Tamron SP 15-30mm f/2.8 Di VC USD (Model A012) is the first ultra-wide angle f/2.8 zoom lens featuring optical image stabilisation, making it ideal for full-frame Canon DSLRs. This professional-grade lens delivers outstanding image quality across the entire 15-30mm range, with sophisticated optical design incorporating XGM (expanded Glass Molded Spherical) and low-dispersion glass elements that efficiently compensate for distortion and chromatic aberration. The integrated Vibration Compensation (VC) mechanism with three electromagnetic coils provides exceptional stability for handheld shooting in low-light conditions. Advanced optical coatings including fluorine coating on the front element repel water and dirt for improved durability. The USD (Ultrasonic Silent Drive) autofocus motor delivers precise, silent operation with full-time manual focus override for fine adjustments. A 9-blade diaphragm produces smooth bokeh effects, and the unique zoom-linked lens hood minimises flare across the entire focal range.
