Review Excerpt

  • Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Sharp, detailed images with very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.

  • Can seem intimidating at first; Fewer autofocus points than competitors; Doesn't take advantage of high-speed UHS-I flash cards; Movie feature set is very dated and file sizes huge.

  • 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
