Buy the Pentax K-30

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.
