SONY - Full Frame E-Mount FE20mm F1.8 Wide Angle G 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.

Customisable focus hold button
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.
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.
Easy manual/auto focus switching
A focus mode switch that allows instant switching between auto and manual focus modes can be a great advantage when shooting subjects or situations that require fine manual focus adjustment.
Switchable aperture ring click stops
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.
30mm equivalent on APS-C bodies
This lens also 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 the scenery while hiking or mountain climbing, and much more. The SEL20F18G is highly recommended for APS-C as well as full-frame users.
Sony's movie technology supports advanced moviemaking
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.
Accepts a variety of filters
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.
