Viltrox AF 20mm f/2.8 20mm

★★★★★ 4.5 (593)

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.

    • Excellent optical quality: sharp in center, good corner performance, bright f/1.8 aperture.
    • Great value for the price: performs like much more expensive lenses, budget-friendly.

    • Autofocus varies from catastrophic to okay after firmware update.
    • Received used/damaged lens with dings, dirty glass, missing cap.

    • Exceptional value for money, outperforming price expectations at ~$160.
