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.

  • Absolutely incredible value; Includes a stabilized kit lens; More versatile than a fixed-lens bridge camera; Comfortable body with good ergonomics; Great image quality; Good autofocus performance; Decent battery life.

  • Feels a bit plasticky; Slow burst shooting with limited buffer; Sluggish to power on or switch modes; Low-res EVF and LCD monitor; Can't review images using EVF; No video output; Weak flash; Battery charges in-camera.
