The 20 mm ultra-wide focal length ensures impressively wide shots.
It incorporates two advanced, pioneering-design AA (Advanced Aspherical) elements.
The aspherical optics dramatically minimize distortion and field curvature.
It also includes three ED (Extra-low Dispersion) glass elements.
It eliminates sagittal coma flare for perfectly rendered points of light.
It delivers impressive resolution across the entire frame, even at the maximum F1.8 aperture.
The Sony FE 20mm F1.8 G is a prime wide-angle lens for full-frame cameras with a Sony E-mount. Its optical design includes two AA aspherical elements and three ED glass elements to reduce aberrations and color distortion. The 9-blade aperture creates smooth bokeh, while the Nano AR coating reduces reflections, flare, and ghosting.
Two XD linear motors support fast, quiet autofocus and tracking. The minimum focusing distance is 0.19 m with autofocus and 0.18 m with manual focus. The lens features internal focusing, dust and moisture resistance, a focus-hold button that can be assigned other functions, and an aperture ring with a switchable click mechanism.
