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.

  • Very good image quality; Improved dynamic range & high ISO quality over T6i; 45-point AF system; Fast Dual Pixel CMOS AF; Improved buffer depth.

  • Default JPEGs slightly soft straight out of camera; Dynamic range & high ISO still lags behind competitors; No 4K video.
