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

  • Outstanding image quality; Fast hybrid AF with phase-detect; 5fps bursts at full resolution; In-body image stabilization; Improved EVF; Weather sealing; 4K UHD & Cinema 4K at up to 30fps.

  • Big and bulky; Shallow buffer depth with RAW files; Vertical grip not as comfortable; Native lens selection still limited.
