Thirteen elements in 11 groups. Nine aperture blades. The 62mm filter thread. At 464g the lens is moderate. Minimum focus distance of 0.28m. DC motor autofocus — workable AF speed but audible by modern standards; not ultrasonic-class. f/2 maximum aperture. Full-frame coverage (Sony FE). Sony FE mount.
The FíRIN 20mm f/2 FE AF is the autofocus successor to the earlier FíRIN 20mm FE MF (manual-focus only, 490g, same optical formula). The 20mm f/2 full-frame combination provides a wide ultra-wide perspective at f/2 — enabling shallow depth of field and low-light performance at the 20mm focal length. The DC motor is audible but functional for still photography.
On the used market the Tokina FíRIN 20mm f/2 FE AF is affordable as a Sony FE ultra-wide prime at f/2. Condition checks: DC motor AF response (audible AF is normal), 62mm front element for marks. Full-frame (FE). Compatible with all Sony FE-mount full-frame and APS-C E-mount bodies.
