Review Excerpt

  • Very compact for a weather-sealed DSLR; Good ergonomics and great viewfinder; Excellent image quality; Decent performance for its class; Articulated screen is great for difficult compositions; Offers features not found in other Pentax DSLRs

  • 18-50mm kit lens is fiddly and prone to jamming when retracted; Wi-Fi is slow and unintuitive; Slow startup; Limited movie mode; Poor battery life for a DSLR; Priced too close to its enthusiast-grade sibling

  • 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
