Review Excerpt

  • Smaller than SLR/CSC with comparable lenses; Larger sensor than other bridge cameras; SLR-like body without the hassle of changing lenses; Weather-sealed; Constant f/2.8 maximum aperture; Generous zoom range; Great viewfinder; Swift performance; Plenty of enthusiast-friendly features including raw shooting; Wi-Fi and NFC wireless sharing.

  • Expensive compared to other bridge cameras; Menus respond slowly after burst shooting; Lens doesn't zoom very quickly; High ISO performance doesn't quite match RX100 II.

  • Read our Sony RX10 Review

  • 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
