Offering a wide angle of view for full frame cameras, the Canon EF mount Tamron SP 15-30mm f/2.8 Di VC USD Lens is a fast wide-angle zoom lens with Vibration Compensation. The f/2.8 maximum aperture performs well in low-light situations, and provides a shallow depth of field for selective focus. Further benefitting the lens is the VC (Vibration Compensation) image stabilization, which helps to minimize the appearance of camera shake to enable the use of longer shutter speeds or smaller apertures when hand-holding in low-light conditions. XGM and LD glass elements reduce chromatic aberrations and help ensure sharp and clear imagery. eBAND and BBAR coatings render uniform colors and reduce ghosting and flare, while a fluorine coating on the front element helps repel water or contaminants. A USD (Ultrasonic Silent Drive) autofocus motor provides quick and precise focusing performance, with high torque, low response times, and quiet operation to benefit both still and video applications. Additionally, a full-time manual focus mechanism enables manual fine-tuning of focus at any point, even when the AF system is engaged.
