Here are some of the notable features included on the new Sony FE 20mm F1.8 G prime lens:

  • It has a minimum focus distance of just 7.5 inches and up to 0.22x magnification for close-up photography.
  • The lens includes XD linear focus actuators with fast, precise and quiet AF tracking for still photography and video.
  • The lens has an optical design that includes two advanced aspheric (AA) lens elements, three extra-low dispersion (ED) elements and a Nano AR coating, which Sony says allows the lens to have stunning resolution and beautiful, natural-looking bokeh.
  • It has a manual focus ring, an aperture ring with click stops, a focus-mode switch, a focus-hold button and a 9-blade circular aperture mechanism.
  • Sony also says the lens has a dust- and moisture-resistant design.

According to Sony, the new lens has an optical formula (specifically two AA and three ED glass elements) that allow it to accurately reproduce point light sources with high contrast and with a minimum of sagittal flare (which is an unnatural spreading of point light sources and is most common in large-aperture lenses).
