If you are predominantly a stills shooter it is very hard to not recommend the Pentax K-30. It handles well, comes with an intuitive and thought-out user interface, has an excellent feature set for its price point, including weather-sealing and a fast 6 fps continuous shooting mode, and offers excellent image quality across the ISO range which can be further improved by shooting and processing Raw files.
As you can see most of the bullet points in the 'Cons' list at the top of this page are related to the K-30's video mode and if you are planning to regularly use the K-30 for capturing video the story is a slightly different one. While it records smooth and detailed 1080p video footage with no dedicated movie button, no external microphone socket and no ability to use AF during video recording the K-30 is not the obvious choice for any photographers who are thinking about venturing into more serious videography. Competitors such as Canon with the EOS 650D/Rebel T4i or Sony with the SLT-A65 offer more compelling products for this type of user.
For anyone else the Pentax K-30 is a very easy recommendation. It's at the top of its class in terms of feature set and high ISO performance, with Raw files that offer more processing flexibility than any other camera in its class. You'll have to decide for yourself if the K-30 is good enough to make you switch from another system but for existing Pentax shooters or new DSLR users focus on stills photography the Pentax K-30 is an excellent choice and easily earns itself our sliver award.
