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

Great image quality; Good high ISO performance for its class; Improved JPEG processing; Fast autofocus; Fast ~9fps burst mode.
Smallish field-sequential EVF; Below average battery life; No mic/headphone jacks; Noticeable crop on 4K video.
