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
