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.

  • Excellent, tank-like build quality; First-rate ergonomics a pro would expect; Superb performance with confident autofocus; Great image quality; Big, bright viewfinder with 100% coverage; Excellent battery life; Doubles as a powerful video capture tool

  • Fairly minor upgrade over the D4; Image quality improvements apply only to JPEG; XQD card format isn't broadly accepted; Consumer-friendly default JPEG processing may turn off some pros; Body is large and hefty (but that's normal for pro gear)
