Manual focus wide-angle prime lens for Sony full-frame mirrorless cameras.
The Tokina FíRIN 20mm f/2 FE MF is an ultra-wide prime for Sony FE full-frame cameras in manual focus configuration. FíRIN (pronounced 'fe-reen') is Tokina's lens series for mirrorless full-frame cameras; FE = Sony full-frame E-mount; MF = manual focus. It includes electronic contacts for EXIF and aperture control.
20mm focal length, f/2 maximum aperture, FE full-frame E-mount with electronic CPU contacts, manual focus (no AF motor), 72mm filter thread.
The FíRIN 20mm f/2 FE MF provides a fast ultra-wide perspective for Sony full-frame photographers who prefer manual focus. The f/2 aperture enables ultra-wide astrophotography and low-light documentary work where conventional ultra-wide lenses are too slow. Electronic contacts enable correct EXIF recording and aperture control via the Sony body.
Test electronic contact communication and aperture control via Sony body. Inspect for fungus, haze, and coating condition. Test focus helicoid smoothness. Confirm Sony FE mount engagement. Test at f/2 for vignetting and corner performance.
