What We Like
+Exceptional value at ~$158-175 USD; compact and lightweight at 157g (E-mount) or 173g (Z-mount)
+High-quality optics with ED glass and aspherical elements deliver sharp center-to-corner results when stopped down
+Silent STM autofocus with Eye AF support; firmware updates via USB-C for continued improvement
+Versatile 20mm focal length ideal for travel, landscape, vlogging, and architecture with 91.6° field of view
Worth Knowing
Strong field curvature at wide apertures limits sharpness edge-to-edge at F2.8; best results at F5.6+
No weather sealing; vulnerable to moisture and dust despite water-resistant front coating
Moderate flare and ghosting resistance; faint patterns visible at F2.8 becoming more defined when stopped down
Plastic construction feels inexpensive despite solid durability; less premium feel than competitors at higher price points

Read our notes on general
The Viltrox AF 20mm F2.8 FE is a super affordable ultra-wide lens that is capable of very good results, though strong field curvature is an issue at large apertures, so for best results you should stop down to f/5.6. With 10 elements in 8 groups it offers outstanding optical performance, achieves beautiful close-ups with a minimum focusing distance of about 0.19m, and the quiet STM focus motor provides accurate and smooth focusing. At merely $160 USD, this budget-friendly option delivers an exceptional value proposition for travel photographers and videographers seeking a compact, lightweight wide-angle prime.
