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

Highest resolution Micro Four Thirds camera yet; Great high ISO performance; Very fast autofocus; Fast burst mode with deep buffers; Impressive Dual I.S. system; Great 4K video.
No built-in flash; Slow buffer clearing; Below average battery life; Limited I.S. for 4K video.
