Review Excerpt

  • Outstanding high ISO performance; excellent dynamic range; 4K video recording (via uncompressed HDMI); XAVC S option for HD video; Slightly improved battery life over A7/A7R; Built-in Wi-Fi & NFC connectivity.

  • 4K video requires expensive external recorder; Sluggish startup time; Loud shutter; Silent Shooting mode hurts image quality; Lacks a built-in, pop-up flash; Limited selection of native Sony FE lenses.

  • Excellent image quality, especially lower ISOs; Improved high ISO performance when using RAW; Very good dynamic range; High-resolution images; Very fast single-shot autofocus; 12fps burst mode with C-AF; Good value for its class.

  • Lackluster continuous AF performance; Strong NR processing in high ISO JPEGs; Sluggish buffer clearing; Short battery life compared to most DSLRs; Joystick control easy to press accidentally.
