Review Excerpt

  • Noticeably better sharpness than standard K-5 II; Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.

  • Prone to moire, aliasing, and false color artifacts; 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.

  • Cheap as chips (and with a kit lens!); Quality Sony Exmor Four Thirds sensor; Widely-supported Micro Four Thirds lens mount; Good image quality from raw files; Reasonable burst performance for price; 4K video capture.

  • Poor ergonomics; Controls too easily bumped; Frustrating user interface; Mediocre JPEG image quality; Heavy-handed noise reduction; Unreliable white balance; No raw+JPEG; Buffer is almost nonexistent; Focus confirmation beep happens while still focusing; AF is poor in low light; Laggy user interface in playback; Extreme crop for 4K video; Kit lenses feel cheap; No bundled flash.
