Sony FE 20mm f/1.8 G Lens

G-Series Optics

Two AA (Advanced Aspherical) and three ED elements minimize distortion, spherical, and chromatic aberrations for crisp, accurate rendering.

Nano AR & Fluorine

Nano AR Coating suppresses flare/ghosting; front fluorine layer repels dust, moisture, and fingerprints for easier cleaning.

Bright f/1.8 Aperture

Great for low light and shallow depth-of-field; 9-blade rounded diaphragm produces smooth, circular bokeh.

Fast, Quiet AF

Dual XD Linear motors with internal focus for fast, precise, and silent autofocus—ideal for both photo and video.

Video-Ready Controls

De-clickable aperture ring, Linear Response MF, AF/MF switch, and customizable focus-hold button for tactile operation.
