The tamron SP 15-30mm f/2.8 Di VC USD, canon EF Fit Lens is a incredibly fast wide-angle
zoom lens with Vibration Compensation. The f/2.8 maximum aperture performs well
in low-light situations, and affords a shallow depth of field for selective
focus. Further benefitting the lens is the VC (Vibration Compensation) image
stabilisation, which helps to minimise 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
colours and reduce ghosting and flare, while a fluorine coating on the front
element helps repel water or contaminants.
