Viltrox AF AF 20mm f/2.8 20mm
The Viltrox 20mm f/2.8 FE weighs only 157g yet offers weather sealing and a fast STM autofocus, making it a remarkably compact full-frame wide-angle. Its optical design with two ED and two aspherical elements pairs well with a 0.19m minimum focus distance for close-up detail. Best suited for landscape and video shooters who need a lightweight, weather-resistant ultra-wide on Sony E-mount.
