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.

  1. Q1 202675/1004.1★8 レビュー

    Buyers praise the lens for sharpness, value, and lightweight design, but note autofocus struggles, close-distance limits, and a coating defect.

    • Sharp, excellent value, lightweight, good for architecture/landscape.
    • Coating faded after 3 months, causing blurriness.
    • Autofocus issues, especially with eye-tracking and fast focusing.
    • Silent autofocus, good bokeh, suitable for travel and hybrid shooting.
  2. Q4 202578/1004.2★13 レビュー

    Most buyers praise the lens for excellent image quality and value, though a few report softness, slow focus, or a used item received as new.

    • 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 is fast for most but can be slow or loud in some cases.
    • One buyer received a used lens in opened packaging; another describes very soft focus for astro.
  3. Q3 202576/1004.8★10 レビュー

    Buyers praised sharpness, portability, and value. Some noted slow autofocus and fragile build, but overall satisfaction was high.

    • Sharpness and image quality exceeded expectations for the price.
    • Autofocus is great for some but very slow for others.
    • Build feels solid but fragile; users handle with care.
    • Compact size and wide angle ideal for travel and vlogging.
  4. Q2 202566/1004.0★10 レビュー

    Reviews in Q2 2025 were mixed: value praised by many, but issues with used/defective items, mount errors, low contrast, and poor autofocus reported.

    • Good value for money, especially for budget-conscious buyers.
    • Autofocus varies from catastrophic to okay after firmware update.
    • Received used/damaged lens with dings, dirty glass, missing cap.
    • Wrong mount delivered (ordered FE, got Z). Low contrast against light sources.
  5. Q4 202490/1005.0★3 レビュー

    Buyers praise the lens quality, depth of field, sharpness, and included lens options, saying they improve photos and work with many cameras.

    • Lens quality is excellent for the price
    • Depth of field and image sharpness are impressive
    • Included lenses enhance photo quality significantly
    • Compatible with many cameras, highly recommended
  6. Q2 202497/1004.9★7 レビュー

    Buyers praise this as the best budget 20mm autofocus lens for Sony/Nikon, citing excellent value, sharp center performance, and fast autofocus for under $200.

    • Exceptional value for money, outperforming price expectations at ~$160.
    • Soft edges at wide apertures; acceptable for most users but not for landscape.
    • Autofocus speed and accuracy rated 80-90% of native Sony lenses.
    • Plastic build concerns; lightweight but less premium feel than metal lenses.
