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.

  • Compact DSLR camera body; Excellent image quality; Reliable single-shot autofocus; Good continuous JPEG shooting performance; New kit lens has improved AF; Great value at current prices.

  • SnapBridge is slow and limited; Poor continuous autofocus; No built-in Wi-Fi; Mediocre video features.
