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. 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. An advanced optical design that includes two AA elements is supported by a refined mechanical system in a G Lens that weighs just 373 g (13.2 oz). 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. 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 minimise sagittal flare so that point light sources are reproduced accurately, without colour smearing. 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 auto focus.
