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.

  • Handles even better than its predecessors; Absolutely spectacular images from the 36-megapixel image sensor; Unusually wide sensitivity range for its resolution; Improved performance and buffer depths; Improved video feature set; Impressive low-light autofocus

  • Prone to moire and false color with some subjects; No longer available with a low-pass filter; Demands excellent lenses for the best detail; White balance tends warm under tungsten lighting
