Review Excerpt

  • Exceptionally detailed and uniquely beautiful image quality at low ISOs; Fast, sharp 28mm-equivalent lens; Simple, straightforward controls match camera's simple, straightforward (street photography) goals.

  • Fixed-focal-length lens; Image quality deteriorates significantly at ISO 800 and above; Overall sluggish performer; Falls short when capturing JPEGs; Terrible VGA-only video quality; Very poor battery life; No built-in flash.

  • Unlocks the full potential of full-frame Pentax lenses; Excellent image quality; Great ergonomics and build; Very compact for full-frame; Decent performance; Fast autofocus with great low-light capabilities; Very wide sensitivity range; Bright, accurate viewfinder; Articulated LCD; Stabilization, Wi-Fi and GPS in-camera

  • No built-in flash strobe; Quite heavy compared to APS-C flagships; Somewhat soft images and blown highlights by default in JPEG mode; Warm Auto white balance indoors; Slow startup and buffer clearing; Small top-deck status display; Weak viewfinder illumination; Below-average battery life for DSLR
