Sony FE 20mm f/1.8 G Lens
Ultra-Wide, Lightweight G-Series Prime for Stills and Cinema
The Sony FE 20mm f/1.8 G is a sleek, ultra-wide-angle prime lens that beautifully pairs premium G-series optics with a highly portable, travel-friendly form factor. Delivering a dramatic perspective that is perfect for expansive landscapes, architectural interiors, astrophotography, and high-end vlogging, this full-frame E-mount lens features a bright f/1.8 maximum aperture to excel in low-light environments. Driven by a dual XD Linear Motor system for pinpoint autofocus and featuring a physical de-clickable aperture ring, the FE 20mm provides the precise tactile handling and fast performance required by both elite photographers and cinematic filmmakers. Please note: This lens includes the front and rear caps but does NOT come with a lens hood.

Key Features & Engineering
Dramatic Ultra-Wide Perspective: Features a wide 20mm field of view on full-frame sensors, making it an excellent choice for environmental filmmaking, real estate, and wide-open vistas. On APS-C format camera bodies, it provides a highly useful 30mm equivalent focal length.

Bright f/1.8 Maximum Aperture: The wide f/1.8 aperture supports shooting in low-light or indoor environments and enables a shallow depth of field, all while keeping the physical barrel size impressively compact.

Premium G-Series Optical Layout: Incorporates two Advanced Aspherical (AA) elements to drastically suppress distortion and edge-to-edge spherical aberrations, alongside three Extra-Low Dispersion (ED) elements to eliminate color fringing and chromatic defects.

Sony Nano AR & Fluorine Coatings: Coated with Sony’s proprietary Nano AR layer to effectively minimize surface reflections, lens flare, and ghosting for rich contrast. The front element features a protective fluorine coating that repels water, fingerprints, and dust.

Dual XD Linear AF Motors: Outfitted with two high-torque XD (Extreme Dynamic) Linear Motors that deliver rapid, quiet, and incredibly precise autofocus tracking for high-frame-rate stills and video production.

Professional Video Optimization: Features a physical aperture ring that can be mechanically de-clicked via a barrel switch for smooth, silent iris adjustments during filming. The manual focus ring utilizes a Linear Response mechanism for natural, repeatable focus pulls.

Tactile Controls & Filter Support: Equipped with a customizable focus hold button and a dedicated AF/MF toggle switch for quick setting changes. Unlike many ultra-wide optics, it features a standard 67mm front thread to accept screw-in creative filters.

Compact, Weather-Sealed Chassis: Weighing a mere 12.3 oz, this low-profile lens is perfectly optimized for balanced handheld vlogging, gimbal stabilizers, and travel setups. The entire barrel is dust- and moisture-sealed for confident use in inclement weather.
