Review Excerpt

  • Incredibly small body for a fully-featured, full-frame camera; Resolution that rivals a medium-format camera; Excellent image quality even at very high sensitivities; Decent performance bearing in mind its extremely high resolution; Accepts existing Alpha-mount and E-mount lenses, and can optionally crop to APS-C image circle.

  • Extreme resolution makes focus and lens quality critical; Modest performance; Loud shutter; Lacks hybrid autofocus of the A7; Mediocre battery life when using electronic viewfinder; Slow X-sync; Limited selection of native Sony FE lenses.

  • Great image quality especially from RAW files; Excellent dynamic range for a Four Thirds sensor; Very good high ISO performance; Realistic colors and excellent hue accuracy; Built-in Wi-Fi with remote control and sharing features; Improved HD video; Lightweight and very portable; Built-in pop-up flash; Minimal EVF lag time.

  • Contrast-Detect AF struggles with small and low-contrast subjects; Mediocre battery life; No external microphone or headphone jack; Mediocre burst speed with continuous AF; No weather sealing; Heavy-handed high ISO noise reduction.
