Sony G SELP1020G 20mm
Weighing just 179g and measuring 2.25 inches, this ultra-wide zoom maintains constant f/4 aperture across the 10-20mm range with fast linear AF and weather sealing. Three aspherical elements suppress astigmatism while the power zoom system reduces focus breathing for steady video capture. Best suited for travel vloggers and handheld run-and-gun shooters needing a lightweight, stabilized wide-angle on Sony APS-C bodies.
