Advanced Optical Performance
A state-of-the-art optical design with two AA (advanced aspherical) elements and three ED (Extra-low Dispersion) glass elements accurately reproduces point light sources with high contrast and an absolute minimum of sagittal flare for crisp, clear images of challenging subjects such as night scenes and starry skies. The Nano AR coating suppresses reflections, flare and ghosting, while the fluorine coating on the front lens element repels water, oil, and other contaminants for sharp, clear images.
Beautiful, natural-looking bokeh
The deep, beautiful bokeh available with a max. F1.8 aperture is enhanced by a 9-blade circular aperture mechanism and precise control of spherical aberration characteristics that influence the defocused background quality. The FE 20mm F1.8 G lens delivers the type of smooth, natural-looking bokeh that discerning users have come to expect from a G Lens.
Two AA (Advanced Aspherical) lens element
The 20mm F1.8 G lens employs two precision AA (Advanced Aspherical) elements to maximize resolution and effectively compensates for field curvature and astigmatism that can be problematic in wide-angle lenses, achieving high corner-to-corner resolution even with the narrow depth-of-field produced at the lens’s maximum F1.8 aperture.
Three ED glass elements Three ED (Extra-low Dispersion) glass elements significantly reducing flare and ghosting by taking axial chromatic aberration and chromatic aberration (due to differences in magnification) out of the picture. Resolution and bokeh is maximized while leaving precisely rendered edges with no fringing or unnatural coloration right out to the image edges.
F1.8 max aperture
The F1.8 max aperture maintains exposure and depth of field, allowing you to isolate your subject from the foreground and background with amazing light gathering capabilities when shooting wide open. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. This ‘bokeh’ effect of the blurred background is enhanced with circular aperture blades used in this lens.
XD Linear Motors for fast, precise, quiet focusing
The FE 20mm F1.8 G lens incorporates a precision internal focus mechanism consisting of two XD (extreme dynamic) Linear Motors that easily keep up with the high-speed capabilities of today’s most advanced camera bodies, taking advantage of their full autofocus speed, precision, and tracking potential to capture the most dynamic subjects. New control algorithms make it possible to drive the lens’s focus group smoothly and without delays for responsive, silent, low-vibration and continuous autofocus in both still and video modes.
Nano AR coating suppresses reflections, flare and ghosting
Flare and ghosting are often hard to avoid when shooting landscapes or outdoor scenes in strong sunlight with a wide-angle lens. Sony’s original Nano AR Coating technology effectively suppresses internal reflections so that high-contrast, clear images can be captured even in difficult light.
Compact, lightweight design
This lens weighs just 0.82lb. (373g) and measures in at only Φ2.89” x 3.33“(Φ73.5 x 84.7 mm). It’s small size and light weight enhance mobility when used with compact E-mount Full-frame or APS-C bodies and make up a well-balanced system that is ideal for use on gimbals or accessory grips.
30mm equivalent on APS-C bodies
The FE 20mm F1.8 G lens is highly recommended for APS-C as well as full-frame users. It balances well on smaller APS-C format bodies, providing a very useful wide-angle focal length of 30mm (full-frame format equivalent). 30mm is great for taking snapshots around town, shooting scenery while hiking or mountain climbing, and much more.
Aperture ring with switchable click stops
In addition to providing the fast, hands-on response required for still and moviemaking applications, the FE 20mm F1.8 G lens’s aperture ring includes a switch that turns its click stops on or off: ON for tactile feedback when shooting stills, or OFF for silent control when shooting movies. The combination of quiet XD Linear Motors and the quiet operation available when the click stops are off is not only great for smooth, seamless aperture control when shooting movies, but also for shooting theater, concerts, and events where noise must be minimized.
Customizable multi-function focus hold button
The focus hold button not only performs its primary function to lock focus when recomposing but can be customized via the camera body menu settings to a number of other functions depending on your needs. In addition to Focus Hold, these custom functions include: Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.
Instant auto/manual focus selection Instantly and quickly switch between auto and manual focus via an AF/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you or decide to take control and manually focus on the precise point you choose.
Natural, linear manual focus response
Linear Response MF (manual focus) ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control is feels immediate and precise in both still and movie modes.
Dust and moisture resistant1 for robust reliability The dust and moisture resistance1 design make this lens appropriate for heavy-duty outdoor use, especially when combined with a camera that employs weather resistant measures.
The FE 20mm F1.8 G lens has clear advantages for moviemaking. With an ultra-wide 20mm angle of view on full frame bodies and 30mm on APS-C bodies or Super 35mm cameras, two XD (Extreme Dynamic) Linear Motors for fast, precise autofocus and tracking, a bright F1.8 maximum aperture for beautifully defocused background bokeh, excellent close-up performance and a class leading compact and lightweight design, this lens is ideal for all types of content creators. In addition to the small size and light weight, its internal focus design makes it convenient for use on compact gimbals or grips for vlogging and other applications.
Close-up, wide-angle shooting
Get a unique perspective through close-up, wide angle shooting. The combination of high close-up capability of just 7.5” (0.19m) with a max. magnification of 0.2x (when used in AF mode), and 7” (0.18m) with a max. magnification 0.22x (when focused manually) and wide-angle characteristic produces unique expression with dramatic perspectives and beautiful background bokeh. This versatility makes it ideal to get close-up shots of your subject and an excellent choice for gimbal/grip mounting, whether shooting selfies or other subjects.
Fluorine front element coating
The front lens element features a fluorine coating that repels water, oil, and other contaminants, while making it easier to wipe off any contaminants or fingerprints that do become attached to the lens surface.
Accepts a variety of filters
Unlike many other ultra-wide-angle lenses, the FE 20mm F1.8 G Lens accepts 67mm filters. Since its internal focus mechanism means that the front element does not rotate when focusing, circular polarizing filters can also be used when shooting landscapes. Polarizers for landscapes, ND filters for movies, and other filter types can be used for extra creative control.
