Tokina AT-X PRO 11-20mm F/2.8 DX AF For Canon EF

A versatile wide-angle zoom for Canon APS-C-format DSLRs, the AT-X 11-20mm f/2.8 PRO DX Lens from Tokina offers a 17.5-32mm equivalent focal length and features a constant f/2.8 maximum aperture for maintained brightness throughout the zoom range. One P-MO hybrid aspherical element and two glass-molded aspherical element work in tandem to minimize distortions and control various aberrations while three SD ultra-low dispersion elements reduce chromatic aberrations for increased clarity. A multi-layer lens coating has also been applied to further enhance overall light transmission and color accuracy by suppressing lens flare and ghosting. Well-suited to working in a wide variety of situations, this ultra-wide zoom covers an array of wide-angle perspectives while maintaining consistent illumination for working in challenging lighting.

Compatible with Canon APS-C-format DSLRs, this wide-angle zoom provides a 17.5-32mm equivalent focal length and features a constant f/2.8 maximum aperture for consistent low-light performance throughout the zoom range.

One P-MO hybrid aspherical element in the front group pairs with two glass-molded aspherical elements in the rear group to minimize distortions and correct aberrations. Additionally, three SD ultra-low dispersion elements are also incorporated within the lens design to further reduce chromatic aberrations for greater color accuracy and clarity.

Multi-layer lens coatings reduce lens flare and ghosting for greater contrast and maintained color fidelity.

A one-touch focus clutch mechanism permits seamless switching between autofocus and manual focusing positions, and the focusing ring features a moderate amount of torque for more fine-tuned control over the focusing position.

An internal focusing mechanism maintains the overall lens form factor during operation.
