SEL20F18G

La plus récente technologie optique de Sony permet l’obtention d’une impressionnante résolution d’un coin à l’autre à l’ouverture maximale de F1.8 avec un objectif grand angulaire à grande ouverture. Étonnamment compact, cet objectif s’adapte à un boîtier à monture E pour constituer un système mobile avec des performances exceptionnelles en matière de mise au point automatique, de contrôle et de fiabilité pour une grande variété de situations de prises de vue.

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

In addition to precise control of spherical aberration that has a significant influence on bokeh quality, the FE 20mm 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.

An advanced optical design that includes two AA elements is supported by a refined mechanical system in a G Lens that weighs just 373 grams (13.2oz.). 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 20mm F1.8 G is a versatile lens for a wide variety of still and movie shooting situations.

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

Two XD (eXtreme Dynamic) Linear Motors easily keep up with Sony’s high-speed camera bodies, taking full advantage of their AF speed, precision, and tracking potential. New control algorithms make it possible to drive the lens’s large focus group smoothly and without delays for responsive, silent, low-vibration autofocus.

A dust and moisture resistant design⁰ provides the reliability needed for outdoor use in challenging conditions.

En plus d’une distance focale géniale de 20 mm pour les autoportraits, l’objectif a une distance minimale de mise au point de 0,19 m lors de l’utilisation en mode AF, et une distance de 0,18 m avec la mise au point manuelle. Il est un excellent choix pour le montage sur cardan/poignée, pour les autoportraits ou les prises de vue d’autres sujets.

Sony 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 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.

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.

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.

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.

Un interrupteur de mode de mise au point qui permet le passage instantané du mode auto au mode manuel peut être un gros avantage lorsque vous prenez en photo des sujets ou des situations qui demandent un réglage fin de la mise au point manuelle.

Cet objectif est également bien adapté aux appareils APS-C plus petits, en procurant une distance focale grand-angle très pratique de 30 mm (équivalent au format plein cadre), idéale pour les clichés en balade, les photographies de paysage en randonnée ou en montagne, et bien plus encore. Le SEL20F18G est hautement recommandé pour les utilisateurs d’appareils APS-C et plein cadre.

Unlike many other ultra-wide-angle lenses, the lens accepts circular polarising filters for landscapes, ND filters for movies, and other filter types so the user has full creative control.

Moviemaking advantages include fast, precise AF and tracking provided by the lens’s XD Linear Motors, an ultra-wide 20mm angle of view on full frame bodies (30mm 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.
