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.
Read our Pentax K-30 Review

Very compact body fits in a pants pocket; Zoom lens is both brighter and further-reaching than anything offered by its enthusiast compact rivals; Selfie-friendly tilting LCD monitor; Intuitive touch-screen interface; Very good image quality for its class; Wi-Fi connectivity gets photos on your phone
No electronic viewfinder; Soft corners at wide-angle; Flare issues and fringing shooting wide-open; Weak performance when shooting raw files; Tendency to underexpose in low light; Limited battery life
