Conclusion: If you can get past the lack of an HDMI-out and mediocre video, the K-30 is an okay DSLR, especially for someone with a collection of Pentax lenses. But to be honest, this camera is in no-man’s land. It doesn’t have all the features of an enthusiast DSLR and is too expensive for an entry-level buyer.
Pros: Decent stills with enough light, Quick response (6 fps), Top-notch screen, Weather-resistance construction
Cons: Poor video quality, Very noisy mechanical operation, No HDMI out, Poor flash results
Summary: Conclusion With a feature set commensurate with its designation by Pentax as a mid-level DSLR, the K-30 is nevertheless the current entry-level model in the Pentax line. It's a short line to be sure, consisting of the K-30 and the K-5II/s. The K-5 is still available, but its price slots it between the K-30 and its newer sibling. Like it or not, the K-30 is your weapon of choice if an entry-level Pentax DSLR is on your shopping list.
Conclusion: With the K-30 digital SLR, Pentax has done something pretty impressive. The company has managed to take several very worthwhile features that its rivals reserve for their enthusiast and pro-oriented cameras, and place them in a mid-range camera. If you don't already have an investment in glass for a competing mount--or if your investment isn't great enough to prevent you jumping ship--then Pentax has given you several very good reasons to consider choosing the K-mount...

Cons: Larger than some recent Pentax mid-range SLRs (but no more so than competition), Reversed Live View / Playback button placements, Default saturation, contrast and sharpening a bit high, Contrast setting impacts saturation, High ISO NR "Off "setting still applies relatively strong noise reduction to red channel, Noise reduction applied to raw files above ISO 1,600 that can't be disabled, Below average battery life from rechargeable lithium-ion battery pack, Buffer dept...
Summary: Pentax’s DSLRs have always formed their own niche in the camera market. While Canon and Nikon’s lines tend to mirror one another, Pentax’s “entry-level” DSLRs have always tended to be more feature-laden than the most basic models from the Big Two. For instance, while last year’s Canon EOS Rebel T3i costs about $150 less than the Pentax K-30 when both are paired with their 18–135mm f/3.5–5.6 kit lenses, the T3i and its lens lack the K-30’s weathersealing and can’t keep up...
Excerpt: This colourful entry-level DSLR grabs sharp 16 megapixel shots, and it's nimble too, with a burst mode of six frames per second - perfect for capturing fast moving sporting moments. Or is it? We check it out in our Cannes group test: hit the video to see what we made of it.
Summary: Also like the Canon T4i, the K-30 lets you add creative effects to your photos such as Bleach Bypass, Reversal Film, Monochrome and more. But the Pentax's movie mode isn't as rich as the Canon's. For example, there's no one-touch record button, no external mic jack, no stereo on-board mic and no HDMI jack for hooking the camera up to your HDTV.
Pros: Weather-sealed, dustproof, coldproof, Intuitive controls, helpful shooting modes, Great viewfinder shows 100 percent of the scene, Faster burst shooting than rival DSLRs
Cons: Slow Live View autofocus, Lacks key video-related features, 18-55 mm kit lens isn't weather-resistant
Excerpt: The Pentax K-30 (priced from $849) is a midrange digital SLR with features found on cameras costing hundreds more. Those features include a fully weather-sealed body (with both front and rear control dials), tons of manual controls, focus peaking, a large optical viewfinder, 6 frame/second continuous shooting, an HDR mode, and support for both AA and lithium-ion batteries.
Excerpt: For 2012, PENTAX has added a new mid-level dSLR to their popular K-series; the K-30. While I wouldn't recommend taking one of these underwater, the K-30 has been designed with over 80 weather-resistant body seals to make the camera hold up in wet, dusty, and sub-freezing conditions.
