Review Excerpt

  • 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
