What's Included

The Sony FE 20mm f/1.8 G offers an ultra-wide perspective in a compact, lightweight design. This prime lens excels with its sophisticated optical construction and user-friendly operation. Perfect for capturing architecture, interiors, landscapes, and vlogs, its portable form factor makes it an essential wide-angle choice for both daily photography and travel.
G Lens Series
Incorporating two Advanced Aspherical (AA) elements, this lens significantly minimizes distortion and spherical aberrations to deliver sharply defined images. Three extra-low dispersion elements further reduce chromatic aberrations and color fringing, enhancing clarity and color fidelity. The Nano AR Coating suppresses surface reflections, flare, and ghosting, ensuring higher contrast and vibrant color reproduction even in challenging lighting. Its bright f/1.8 aperture facilitates shooting in low light while maintaining a compact design. Additionally, the rounded nine-blade diaphragm produces smooth, attractive bokeh when using selective focus.
Autofocus and Handling
The Dual XD Linear Motor system combined with an internal focusing mechanism delivers fast, silent, and accurate autofocus, ideal for both photography and videography. The Linear Response manual focus provides a natural feel, while the AF/MF switch on the lens barrel allows easy toggling between modes. Customizable focus hold buttons offer intuitive tactile access to preferred settings. A physical aperture ring that can be de-clicked enables smooth and silent aperture adjustments, enhancing video work. Despite its ultra-wide prime design, the lens accommodates 67mm front-threaded filters, facilitating creative flexibility.
Compact, Portable Design
Weighing only 350g, this compact lens is perfect for vlogging and everyday shooting, complementing APS-C cameras and stabilizers like gimbals or accessory grips. Its dust- and moisture-resistant construction ensures reliable performance in challenging environments, while rubberized control rings enhance grip in cold conditions. The front element features a fluorine coating that repels dust, moisture, and fingerprints, allowing for easy cleaning.
