Sony's premium G-series 20mm ultra-wide prime — fast f/1.8 with outstanding optics and compact design.
The Sony FE 20mm f/1.8 G launched in 2020 as Sony's premium ultra-wide prime for full-frame E-mount. The G designation indicates Sony's second-tier premium optics. At 20mm f/1.8, it provides an ultra-wide perspective with a fast aperture — ideal for astrophotography and landscapes.
Optically excellent — sharp across the frame from f/2.8 with impressive centre performance at f/1.8. Minimal coma and sagittal flare make it outstanding for astrophotography. Dual XD Linear Motor AF is fast and near-silent. Minimal focus breathing for video work.
Sony FE mount with 67mm filter thread — accepts standard screw-on filters. Weighs just 373g — compact for a fast ultra-wide. Dust and moisture resistant. Minimum focus distance 19cm — impressive close-up capability. Focus hold button. Aperture ring with click/de-click switch.
Available used at mid-range prices. The 67mm filter thread is a major practical advantage over bulbous ultra-wides — screw-on ND and polarising filters work. Outstanding for astrophotography and landscape. The Sigma 20mm f/1.4 Art is faster but much heavier. One of Sony's best G-series lenses.
