  1. Q2 202595/1005.0★6 レビュー

    Buyers love the camera's image quality and portability. One order arrived missing a lens, but seller communication resolved it. Bag quality noted as modest.

    • Great image quality and fast autofocus, especially for travel and wildlife.
    • Camera is lightweight, easy to use, and comes with many accessories.
    • Missing lens in one bundle; seller handled well but delayed delivery.
    • Included strap bag could be bigger or better quality.
  2. Q1 202460/1004.0★7 レビュー

    Buyers praised the camera's size, viewfinder, and photo quality, but noted high price, poor battery life, and high-ISO noise.

    • Compact, lightweight design with viewfinder and good photo quality.
    • Price is high for an older model compared to competitors.
    • Battery life is poor, and high-ISO performance is noisy above 1200.
    • Flip-up screen is awkward behind hot shoe; some delivery issues.
  3. Q1 202288/1004.8★5 レビュー

    Buyers praised build quality, photo results, and ease of use for beginners, but one long-term user continues to dislike the menu system.

    • Excellent build quality and photo results.
    • Great for beginners; enjoyable to learn and use.
    • Menu system is frustrating even after years of use.
    • Highly recommended; buyers would purchase again.
  4. Q4 202178/1004.7★9 レビュー

    Buyers praise the camera's picture/video quality and bundled accessories, but some report a fatal USB connection/software glitch and find menu navigation complex.

    • Great picture and video quality, butter-smooth video, and easy operation.
    • Bundled accessories (lenses, filters, software) are valued and make the kit convenient.
    • USB connection verification fails in an endless loop, rendering software features unusable.
    • Menu navigation is more complicated than other cameras; some accessories feel cheap.
  5. Q3 202180/1004.2★5 レビュー

    Buyers praise the camera as a good upgrade for students and hobbyists, though one had a denied transaction.

    • Great for students and junior hobbyists due to lightness and features.
    • No overheating issues, unlike the a6300 model.
    • Learning curve steeper than expected, especially from DSLR.
    • Order denied for unknown reasons, no product received.
  6. Q2 202183/1004.6★27 レビュー

    Buyers in Q2 2021 generally praised the a6400's autofocus, compact size, and value. However, a notable complaint highlighted the lack of in-body stabilization causing blur when shooting hand-held in low light.

    • Autofocus is fast and accurate, including for eye tracking and small subjects.
    • Compact, lightweight, and good build quality; a solid upgrade from older DSLRs.
    • Great value for entry-level to mid-level shooters, especially in bundles.
    • No IBIS causes hand-held blur; users advise using stabilized lenses or tripods.
  7. Q1 202188/1004.6★19 レビュー

    Buyers praised the camera for its value, low-light video performance, and autofocus, but one reported a viewfinder failure after five months with poor support.

    • Excellent value and affordability for the quality offered.
    • Great video quality and reliability, including long 4K recording.
    • Fast autofocus and sharp image quality appreciated.
    • Viewfinder flipped upside-down after five months; Sony support poor.
  8. Q4 202086/1004.9★7 レビュー

    Buyers praised the camera's quality, value, and features as a mirrorless option under $1000. Some noted software issues on Mac and lacked double exposure capability.

    • Excellent image and video quality, great for beginners and enthusiasts.
    • Software programs did not work on Apple computers; buyer beware of compatibility.
    • No built-in multiple or double exposure capability; needed update.
    • Forgivable rolling shutter at this price point for video use.
