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.

  • Read our Sony A7 Review

  • Compact and lightweight for a fully-featured interchangeable-lens camera; Really fast autofocus; Good all-around performance too; Generous buffer depth; Versatile tilt/swivel LCD and high-res viewfinder; Touch-screen controls; Very affordable pricetag

  • Out of the box, colors are muted by consumer standards; Warm white balance under incandescent light; Handgrip is a little shallow for those with larger hands; Wi-Fi is overly complex and has limited range
