Overview

The Tokina atx-m 23mm F1.4 offers strong center sharpness wide open but soft corners until f/2.8, with peak performance at f/4-f/5.6. Vignetting is heavy at f/1.4, distortion is minimal, and bokeh is pleasing with smooth transitions. Build quality is high with a metal body and step-less aperture ring, but lacks weather-sealing. Autofocus is moderately fast and quiet. It suits photographers seeking a compact, fast wide-angle for APS-C, especially street and video shooters, though competitors offer better edge sharpness.
