Review Excerpt

  • Improved 20.1-megapixel resolution; Impressive image quality, especially for its price; Fast and decisive autofocus (in most conditions); Very good battery life; Good video quality (Full HD 1080p, though it doesn't support 60p frame rate).

  • Plastic lens mount; Slower burst mode speeds and shallower buffer than A57; LCD no longer fully articulating; Mediocre kit lens; Electronic instead of an optical viewfinder may be a turnoff for some.

  • 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
