Key Features — Tokina AF 11-20mm f/2.8 SD IF DX
11-20mm Zoom Range: Covers an ultra-wide field of view on APS-C cameras, equivalent to roughly 17-30mm full-frame, suitable for landscapes, architecture, and interiors.
Constant f/2.8 Aperture: Maintains f/2.8 throughout the entire zoom range, ensuring consistent exposure settings and depth of field control whether shooting at 11mm or 20mm.
APS-C Format Design: Optimized for APS-C sensor DSLRs, delivering edge-to-edge image quality across the full sensor area without vignetting.
Canon EF & Nikon F Mounts: Available in two of the most widely used DSLR mount systems, making it accessible to photographers already invested in either ecosystem.
One-Touch Focus Clutch: Tokina's signature focus clutch mechanism lets you instantly switch between autofocus and manual focus by sliding the focus ring forward or back.
Internal Focus (IF): The lens focuses internally, so the front element does not rotate or extend during focusing, which is beneficial when using polarizing or graduated ND filters.
