Review Excerpt

  • Pentaprism viewfinder is bright and accurate; Weather-sealed body can handle direct rain; Twin control dials make exposure control a snap; Solid build; Great image quality.

  • Lower resolution than some rivals; Not as small as recent Pentax entry-level and mid-range models; A couple of ergonomic and UI quirks; Shutter isn't the quietest; 18-55 kit lens isn't weather-sealed.

  • Excellent image quality with lots of fine detail; Very good high ISO performance; Good dynamic range; Good print quality; Deep buffers with JPEGs; 1080/60p video; Uncompressed HDMI output.

  • AF struggles in low-light; Contrast-detect AF in live view is slow; Buffer depth is shallow with RAW files; No AE bracketing; No built-in Wi-Fi.
