The Tamron AF18-270mm f/3.5-6.3 Di-II VC PZD AF Lens for Canon is a 15x high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-419mm in 35mm format. Designed as an all-in-one lens, it will meet almost all photographic opportunities without changing lenses. The addition of PZD (Piezo Drive) ultrasonic autofocus motor helps make this lens lighter, shorter and slimmer than any previous lens in this category, and provides faster, quieter auto-focusing. The VC (Vibration Compensation) mechanism allows the use of shutter speeds that are much slower than otherwise possible, with no perceptible increase in image blur. It automatically detects movement of the camera and compensates for camera shake when shooting a moving object. This feature is a must in a lens with this longer range of focal length. This lens will focus down to 19.3 (0.49 m) throughout the zoom
