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.

  • Excellent image quality for a 1/1.7" sensor; Versatile 28-200mm eq. lens with fast f/2-4 max aperture; Built-in EVF; Fully articulating LCD; Generous set of physical controls; Built-in flash with wireless support; Standard dedicated hot shoe; Full HD and slo-mo movies.

  • Slow cycle times and buffer clearing with RAW files; Shallow burst mode buffer; Mediocre autofocus speed and shutter lag; Sluggish UI at times; Slow to switch to movie mode; Optical zoom not supported during movie recording when using manual exposure modes; No built-in Wi-Fi.
