Review Excerpt

  • Incredibly small body for a fully-featured, full-frame camera; Very high resolution; Hybrid autofocus is reasonably fast and confident; Significantly better burst-shooting performance than A7R; Excellent image quality even at very high sensitivities; Faster x-sync than A7R; Accepts existing Alpha-mount and E-mount lenses, and can optionally crop to APS-C image circle.

  • Grass-is-greener syndrome when compared to its higher-res sibling; Moderate performance; Loud shutter (but electronic first-curtain helps); Mediocre battery life when using electronic viewfinder; Weak low-light autofocus considering its price; Limited selection of native Sony FE lenses.

  • Sharp retro design and solid build; High resolution, tiltable electronic viewfinder and LCD touchscreen monitor; Competitive still image quality; Very good video quality, recording Full HD at frame rates up to 60p; Fast autofocusing and all-around performance; Robust Wi-Fi and NFC capabilities, including remote shooting when paired with a smart device

  • Weak built-in flash; No external mic or headphone jack for video recording; Some poor results when shooting in Creative Panorama mode
