The Pentax K-30 offers a comprehensive feature set, excellent high-ISO performance, and very flexible raw files at an attractive price point, and is therefore an easy recommendation for any stills photographer. However, if you are looking for a DSLR to shoot video with, the competition offers better alternatives.

DCRP Review: Pentax K-30
By: Jeff Keller, Digital Camera Resource Page (Sep 17, 2012)
Overall, it's pretty hard not to like the Pentax K-30. For $850 (body only), you get a well-equipped, weather-sealed D-SLR that takes great photos. Sure, I wish it had better battery life, stereo sound recording, and HDMI output, but aside from those issues, there's little to complain about.
Pentax K-30 Review

For a mid-price DSLR, the K30 certainly offers a lot. The sensor has been adopted from previous models, but this is a wise move by Pentax as the 16.3Mp CMOS chip certainly delivers impressive results.
