Tokina 11-16mm f/2.8 AT-X Pro SD (IF) DX II Autofocus APS-C Lens for Canon EF-S Mount {77}

The Tokina 11-16mm Aspherical AT-X Pro lens is everything that a photographer could desire in a lens. Tokina's One-Touch Focus Clutch Mechanism allows the photographer to switch between autofocus and manual focus with a simple push of the focus ring. Snapping it forward into autofocus and back into manual focus is all that needs be done, there's no need to adjust the AF/MF switch on the camera body. A f/2.8 maximum aperture benefits working in low-light situations and also aids in creating a shallow depth of field. An internal silent focusing motor allows the lens to use autofocus on Canon bodies that do not have an AF drive gear and motor. Two Super-Low Dispersion glass elements and two aspheric elements, as well as improved multi-coating, achieve excellent sharpness and contrast and reduce aberrations.
