Overview

The Tokina 11-20mm f/2.8 is a well-regarded ultra-wide zoom for APS-C DSLRs, offering excellent center sharpness wide-open and good overall resolution, especially at 16mm f/8. It controls distortion well and has low flare. Weaknesses include softer corners at 11mm and some barrel distortion at the wide end. Build quality is solid, with a constant f/2.8 aperture and 82mm filter thread. Autofocus is accurate but not lightning-fast. It suits landscape, architecture, and interior photographers seeking a fast, versatile ultra-wide zoom.
