High resolution and beautiful bokeh in a compact, lightweight package. This large-aperture, ultra-wide-angle prime lens is ideal for both still and video photography. This lens features cutting-edge optical design and a mirrorless camera body exclusive design, achieving the widest angle of view of any Sony E-mount prime lens at 20mm*. With its ultra-wide 20mm angle of view, a bright f/1.8 maximum aperture, and excellent point image reproduction, it's ideal for landscape, nightscape, and starry sky photography. Its compact and lightweight design makes it easy to mount on a gimbal or grip, as well as its excellent close-up capabilities and quiet AF drive, make it an ideal lens for videography. (35mm full-frame lens) Based on Sony research as of February 2020. Achieve high resolution across the entire frame at an ultra-wide 20mm aperture starting at an f/1.8 maximum aperture. The latest optical design, featuring two AA (advanced aspherical) lens elements and three ED (extra-low dispersion) glass elements optimally positioned, delivers high contrast and sharp images with reduced sagittal flare (the blurring of point light sources). It is particularly effective for nightscape and starry sky photography.
High Resolution Performance with Two Advanced Aspherical AA Lenses: The lens employs two advanced aspherical AA (advanced aspherical) lenses. This effectively corrects field curvature and astigmatism, both of which are common in wide-angle lenses, achieving high resolution performance from wide-open apertures with shallow depth of field to the edges of the frame.
Perfect Image with Three ED Glass Elements: Three ED (Extra-Low Dispersion) glass elements significantly reduce chromatic aberration, effectively suppressing chromatic aberration even at the edges of the frame.
Beautiful, Natural Bokeh and Superior Close-Up Capability: The wide bokeh achieved by the f/1.8 aperture and the use of a nine-blade circular diaphragm control spherical aberration, which affects the bokeh effect. This lens delivers the beautiful, natural bokeh you expect from a G lens. It also boasts excellent close-up capabilities, with a minimum focusing distance of 0.18m (MF mode). Nano AR coating provides excellent backlight resistance. When shooting landscapes with a wide-angle lens, sunlight is often a factor, potentially causing flare and ghosting due to internal reflections. The FE 20mm F1.8 G employs Sony's proprietary Nano AR coating to suppress flare and ghosting, achieving excellent backlight resistance and high-contrast imaging performance. Despite being a large-aperture, ultra-wide-angle lens, it's incredibly compact and lightweight. Thanks to the latest optical design and optimized mechanical design, this full-frame, large-aperture, ultra-wide-angle lens weighs an impressive 373g. Its portability when paired with a compact E-mount body makes it ideal for a variety of situations, including mobility-requiring scenes and video shooting with a gimbal or grip. Easy-to-use size and angle of view even when mounted on an APS-C body (30mm equivalent in 35mm format). With a well-balanced size and easy-to-use angle of view (30mm equivalent in 35mm format), even when mounted on an APS-C body, it's ideal for a wide range of scenes, from street snapshots to active photography like mountain climbing. Equipped with an "XD Linear Motor" that anticipates the future of camera body speed performance. Equipped with two XD (extreme dynamic) linear motors, it delivers high-speed, high-precision, high-tracking, and quiet AF. Combined with a control algorithm developed specifically for the XD Linear Motor, it enhances responsiveness to control signals, minimizing drive delays and micro-vibrations that often occur when driving large-diameter focus lens elements, resulting in quiet, low-vibration AF drive. It continues to capture even the most fleeting movements, such as in snapshots of action. Abundant video capabilities, culminating in Sony's video technology. The XD Linear Motor delivers high-speed, high-precision, high-tracking, and quiet AF even during video recording. Furthermore, the internal focusing mechanism maintains constant overall length during focusing, enabling comfortable video recording even when the lens is mounted on a small gimbal or grip. Ultra-wide-angle lens, yet compatible with a variety of filters. Despite being an ultra-wide-angle lens, it can accommodate filters up to 67mm in diameter. Internal focusing eliminates the need for rotating front lenses, allowing for the use of circular polarizing filters commonly used in landscape photography and ND filters used in videography, broadening the photographer's creative horizons.
Linear Response MF with Minimal Time Lag and Excellent Responsiveness. The Linear Response MF system responds responsively to delicate manual focusing ring operation. Focus movement is linearly proportional to the ring rotation angle, enabling precise focusing that directly reflects the photographer's intentions.
Supports fieldwork with reliability, including fluorine coating and dust- and weather-resistant features. The fluorine coating on the front lens surface repels fingerprints, dust, water droplets, oil, and mud, and even if they do adhere, they are easily removed. Furthermore, the dust- and weather-resistant design ensures reliability, even in harsh outdoor shooting environments. *Although the lens is designed to be dust-proof and splash-proof, it does not completely prevent dust and water from entering.
