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.

  • Absolutely incredible value; Includes a stabilized kit lens; More versatile than a fixed-lens bridge camera; Comfortable body with good ergonomics; Great image quality; Good autofocus performance; Decent battery life.

  • Feels a bit plasticky; Slow burst shooting with limited buffer; Sluggish to power on or switch modes; Low-res EVF and LCD monitor; Can't review images using EVF; No video output; Weak flash; Battery charges in-camera.
