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.

  • Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size (at low ISOs); Fast x-sync speeds; Unique design is unconventional but comfortable and balanced.

  • Poor high ISO performance; Very sluggish buffer clearing; Poor low-light AF; No built-in flash; Very limited third-party RAW file support; Bundled Sigma Photo Pro RAW software is slow and buggy.
