Overview

The Tokina AT-X 16-28mm f/2.8 Pro FX is a solidly built, heavy ultra-wide zoom with optical performance rivaling the Nikon 14-24mm f/2.8 at a lower price. It is sharp across the frame, with moderate barrel distortion at 16mm that clears up by 24mm. Key weaknesses are the inability to use filters due to the protruding front element and a limited 16-28mm range. It suits landscape and architecture photographers on full-frame who prioritize optical quality and speed over filter compatibility.
