Sony FE SEL20F18G 20mm
Combining a bright f/1.8 aperture with a 20mm ultra-wide perspective in a compact 373g body, this lens delivers sharp, aberration-free images thanks to two aspherical and three ED elements. Its dust- and moisture-sealed construction and fast, precise dual XD linear motor autofocus make it a reliable tool for run-and-gun shooting in challenging conditions. This lens is best for vloggers and landscape photographers who need a portable, high-resolution wide-angle prime with strong close-up capability.
