Review Excerpt

  • Excellent image quality, especially lower ISOs; Improved high ISO performance when using RAW; Very good dynamic range; High-resolution images; Very fast single-shot autofocus; 12fps burst mode with C-AF; Good value for its class.

  • Lackluster continuous AF performance; Strong NR processing in high ISO JPEGs; Sluggish buffer clearing; Short battery life compared to most DSLRs; Joystick control easy to press accidentally.

  • Read our Sony A77 II Review

  • Huge bang for the buck; Great image quality; Excellent high ISO performance; Fast autofocus; Good burst frame rate with deep buffer; Pentaprism viewfinder; Twin control dials; Articulated LCD; Comprehensive weather-sealing and freeze-proofing; Unbelievable wealth of rare to unique (yet very useful) features

  • Wi-Fi wireless communication is slow, clumsy and unintuitive; Video autofocus is prone to hunting or racking focus; Slow buffer clearing; Rather heavy for an entry-level DSLR; Autofocus and metering systems are a bit dated; Below average battery life
