Two AA and three ED elements
Advanced aspherical elements and low-dispersion glass suppress chromatic aberration, so quality holds across the frame even at f/1.8.
The wide-angle, wide-aperture fixed lens achieves unparalleled resolution across the entire lens area, even at the maximum aperture of F1.8, thanks to Sony's latest optical technologies. This compact lens, together with the E-mount body, creates a practical mobile system that delivers powerful and reliable AF and meets a wide range of shooting needs.

An f/1.8 aperture, focusing from 19 centimetres and a weight you feel on a gimbal. Two AA elements and three ED elements hold the rendering into the corners, even wide open.


Turn the detents on for stills and off for video, so no click reaches the soundtrack. Beside it sit a programmable focus hold button and the focus mode switch.

Small dimensions and 373 g keep the centre of gravity close to the body, so a gimbal or add-on grip balances without a fight. On a wide angle used for video, that is half the work.
A minimum focus distance of 0.19 m at 0.2× magnification lets you get closer than a wide angle usually allows — and the background still falls away.

Focusing is fast, accurate and quiet — for stills and for video.
The build resists dust and moisture, and the front element carries a fluorine coating against water and grease.
A common thread size, so polarisers and NDs are easy to come by.
The lens design includes two AA (advanced aspherical) aspherical elements, three Extra-low Dispersion (Extra-low Dispersion) glass ED elements for effective chromatic aberration suppression, which ensure high image quality across the entire image area right to the edges, even at the maximum aperture setting of F1.8. The lens performs exceptionally well in close-up photography with a minimum focusing distance of f 0.19 metres (max. magnification: 0.2 times) and delivers beautiful bokeh.
The FE 20mm F1.8 G's compact design and versatility make it the perfect all-rounder for photographers and videographers alike. The lens weighs only 373 g. Its small size and light weight make it easily portable when used with compact E-mount system camera bodies. This makes it work as part of a well-balanced system that is ideally suited for use with a gimbal and additional grip.
Additionally, the use of two linear XD motors ensures fast, accurate and silent autofocusing for both still photography and video shooting.
The FE 20mm F1.8 G has been designed to be dust and moisture resistant. The front element has been given a fluorine coating, making the lens highly reliable and easy to use. It has a programmable focus lock "focus hold button" and an aperture ring with an on/off switch. It is also compatible with a range of 67mm filters for even more creative use.
