Viltrox AF 20mm f/2.8 20mm
Weighing just 157g with full-frame coverage and weather sealing, this 20mm f/2.8 prime stands out for its exceptional portability without sacrificing optical quality, using 2 ED and 2 aspherical elements. The quiet STM autofocus supports Eye AF and a 7.5" minimum focus distance for dynamic close-ups, while a USB-C port allows for user-installed firmware updates. This lens is best for landscape and astrophotography shooters who need an ultra-light, affordable wide-angle prime for Sony E-mount bodies.
