  1. Q1 2026100/1008 レビュー

    • Filter size differs from other lenses; not a lens fault but inconvenient.
  2. Q4 202585/1004.8★18 レビュー

    • Excellent value for the price, often exceeding expectations compared to expensive brands.
    • Lightweight and compact design, ideal for travel and everyday use.
    • Autofocus is noisy (notable in video) and sometimes sluggish or inconsistent.

  4. Q2 202598/1005.0★5 レビュー

    Reviewers praise the lens for its excellent sharpness, clarity, and value. Autofocus is good, with minor chromatic aberration and a bump-prone manual aperture dial noted.

    • Excellent value, sharpness, and clarity for the price.
    • Manual aperture dial can be bumped accidentally.
    • Autofocus works well; firmware update fixes minor bugs.

  5. Q4 202480/1004.6★5 レビュー

    Buyers praise this prime lens for its fast aperture, sharpness, and build quality at a low price. However, noticeable chromatic aberration in high-contrast scenes is a drawback for landscape and astro photographers.

    • Outstanding value and performance: fast, sharp, well-built, and weather-sealed for under $600.
    • Chromatic aberration, especially purple fringing, is problematic in contrasty scenes like landscapes and astrophotography.
    • Excellent for portraits, street, and indoor use with smooth, silent autofocus and natural field of view.
    • Solid construction feels premium and durable, fits well on smaller bodies like the Sony A6700.

    • Excellent build quality with all-metal construction, including lens hood.
    • Excellent low light performance and good value for price.
    • Return process for defective unit was handled quickly.
