FE 20 mm F1.8 G

Sony SEL20F18G

Features

  • Sony's latest optical technology achieves impressive corner-to-corner resolution from maximum F1.8 aperture in a large-aperture wide-angle prime lens. It is also remarkably compact. Matched with an E-mount body, this lens makes up a mobile system with outstanding AF performance, control and reliability for a wide variety of shooting needs.
  • Two AA (advanced aspherical) elements in an innovative optical design minimize aberration for outstanding corner-to-corner resolution right from the lens's widest F1.8 aperture.
  • In addition to precise control of spherical aberration-which has significant influence on bokeh quality-the FE 20 mm F1.8 G has a 9-blade circular aperture that contributes to smooth, creamy bokeh and natural-looking highlights that are hallmarks of the G Lens series.
  • Two AA (advanced aspherical) elements and three ED (Extra-low Dispersion) glass elements are employed to minimize sagittal flare so that point light sources are reproduced accurately and without color smearing.

A compact high-resolution 20 mm F1.8 prime lens

Sony's latest optical technology achieves impressive corner-to-corner resolution from maximum F1.8 aperture in a large-aperture wide-angle prime lens. It is also remarkably compact, and matched with an E-mount body, makes up a versatile mobile system with outstanding AF performance, control, and reliability for a wide variety of shooting needs.

FE 20 mm F1.8 G Photo Gallery

Ultra-wide 20 mm perspectives, superb resolution from F1.8

Two AA (advanced aspherical) elements in an innovative optical design minimize aberration for outstanding corner-to-corner resolution right from the lens's widest F1.8 aperture.


Compact and lightweight for enhanced mobility and handling

An advanced optical design that includes two AA elements is supported by a refined mechanical system in a G Lens that weighs just 13.2 oz (373 g). Small size and light weight enhance mobility when used with compact E-mount bodies, and make up a well-balanced system that is ideal for use on gimbals or accessory grips. The FE 20 mm F1.8 G is a versatile lens for a wide variety of still and movie shooting situations.


Smooth, natural-looking bokeh

In addition to precise control of spherical aberration-which has significant influence on bokeh quality-the FE 20 mm F1.8 G has a 9-blade circular aperture that contributes to smooth, creamy bokeh and natural-looking highlights that are hallmarks of the G Lens series.


Realistically rendered point sources

Two AA (advanced aspherical) elements and three ED (Extra-low Dispersion) glass elements are employed to minimize sagittal flare so that point light sources are reproduced accurately and without color smearing.


XD Linear Motors maximize AF speed, precision, and tracking

Two XD (eXtreme Dynamic) Linear Motors 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 large focus group smoothly and without delays for responsive, silent, low-vibration autofocus.


Excellent close-up performance, even for selfies

In addition to the fact that 20 mm is a great focal length for selfies, this lens has a minimum focusing distance of just 0.63 ft (0.19 m) when used in AF mode, and an even closer 0.59 ft (0.18 m) minimum focusing distance when focused manually. It is an excellent choice for gimbal/grip mounting, whether shooting selfies or other subjects.


Smooth operation and high reliability in a compact lens

A focus hold button, focus mode switch, aperture ring and other controls are designed and positioned for easy operation and a smooth workflow. Alternative functions that support the user's individual shooting needs can be assigned to the focus hold button via camera body menu settings. The front lens element is fluorine-coated to repel water and grime, and the lens' dust- and moisture-resistant design provides the reliability needed for outdoor use in challenging conditions.

It is an excellent choice for gimbal/grip mounting, whether shooting selfies or other subjects.
  • Sony's original Nano AR Coating creates a precise, regular nanostructure on lens surfaces that does not interfere with light transmission, while suppressing reflections that can cause flare and ghosting. Internal reflections are reduced to an absolute minimum, achieving outstanding clarity and contrast. (1. Nano AR Coating / 2. Glass / 3. Transmitted light)
  • A dust- and moisture-resistant design provides the reliability needed for outdoor use in challenging conditions.
  • Linear Response MF 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 feels immediate and precise.
  • A conveniently placed focus hold button not only offers easy focus hold control, but can be assigned to a variety of other functions from a menu accessed via the camera body.
  • 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.
  • A focus mode switch that allows instant switching between auto and manual focus mode can be a great advantage when shooting subjects or situations that require fine manual focus adjustment.
  • In addition to providing the fast response required for professional application, the aperture ring includes a switch that turns its click stops on or off: ON for tactile feedback when shooting stills, or OFF for seamless, silent control when shooting movies.
  • This lens also balances well on smaller APS-C format bodies, providing a very useful wide-angle focal length of 30 mm (full-frame format equivalent). 30 mm is great for taking snapshots around town, shooting the scenery while hiking or mountain climbing and much more. The SEL20F18G is highly recommended for APS-C, as well as full-frame users.
  • Moviemaking advantages include fast, precise AF and tracking provided by the lens's XD Linear Motors, an ultra-wide 20-mm angle of view on full frame bodies (30 mm on APS-C bodies or with Super 35 angle of view settings), a bright F1.8 maximum aperture, compact and lightweight design, excellent close-up performance and more. In addition to the lens's small size and light weight, its internal focus design makes it convenient for use on compact gimbals or grips for vlogging and other applications.
  • Unlike many other ultra-wide-angle lenses, the lens accepts circular polarizing filters for landscapes, ND filters for movies, and other filter types so the user has full creative control.
