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

  • Read our Pentax K-S2 Review

  • Compact camera body; versatile 10x zoom lens; relatively good high ISO performance; fast autofocus; many good 4K video and photo features.

  • Soft lens at longer focal lengths; no tilting display; small electronic viewfinder; slippery finish on the camera body.
