Review Excerpt

  • Incredibly small body for a fully-featured, full-frame camera; Resolution that rivals a medium-format camera; Excellent image quality even at very high sensitivities; Decent performance bearing in mind its extremely high resolution; Accepts existing Alpha-mount and E-mount lenses, and can optionally crop to APS-C image circle.

  • Extreme resolution makes focus and lens quality critical; Modest performance; Loud shutter; Lacks hybrid autofocus of the A7; Mediocre battery life when using electronic viewfinder; Slow X-sync; Limited selection of native Sony FE lenses.

  • New sensor offers incredible performance; Excellent image quality at low & high ISOs; Very good dynamic range; Phenomenal 20fps burst speed & deep buffer; Very good battery life for a mirrorless; 4K video; Dual card slots.

  • Slow buffer clearing; Only one UHS-II card slot; Touchscreen underutilized; No lossless RAW compression option; No 4K/60p option.
