20mm · f/2
The Tokina Firin 20mm F2 FE AF offers sharp optics with low distortion, though vignetting is high at f/2. Build quality is solid metal but not top-tier; the aperture ring lacks tactile feel. Autofocus is slow and manual focus is indirect. It suits photographers wanting a compact, fast wide-angle for Sony E-mount who prioritize optical quality over handling speed.
