The Tokina atx-i 11-20mm f/2.8 CF is a wide-angle zoom lens for Canon EF cameras with an APS-C sensor. Its constant maximum aperture of f/2.8 maintains consistent brightness throughout the zoom range and allows control over depth of field. The optical design includes aspherical and low-dispersion elements to reduce aberrations and improve sharpness and color accuracy.
Multi-layer coatings help reduce reflections and ghosting in bright or backlit conditions. The One-Touch Focus Clutch mechanism allows quick switching between autofocus and manual focus by pushing or pulling the focus ring, while internal focusing contributes to fast, precise response. The water-repellent coating on the front element makes it easier to clean.
