Pentax debuts adventure-ready, $850 dSLR

The K-30 has the promise of speed and great photos, plus it's dust-and-weather sealed and ready for sub-freezing temperatures.

Pentax

I have to admit: the $900 Pentax K-30 dSLR sounds like a pretty promising replacement for the K-r. Rugged on the outside with the potential for the same excellent photo quality as the K-01 mirrorless ILC, claimed faster autofocus performance than the already fast K-5, and a 100 percent coverage viewfinder that you usually only see in more expensive models all add up to a possibly great start to the Pentax-Ricoh era.

Though it's not "durable" in the same sense as bodies like the Nikon D4 or Canon EOS-1D X, with parts designed to withstand heavy photographic abuse, the K-30 offers weather-and-dust resistance, with claims of usability down to 14 degrees (most cameras only guarantee down to 32 degrees); that said, Pentax makes no claims about battery life at those temperatures. The next least-expensive camera making similar claims is the Olympus E-5 at $1,699. And none of them come in Pentax's selection of colors, which include white and blue in addition to standard black. It has a rubber grip for improved security in adverse conditions.

On the inside, the camera has the same sensor and image-processing engine as the K-01, which has great photo quality for a camera under $1,000. According to Pentax, the new autofocus sensor has a better grade of glass on the phase-detection array for improved performance. It offers peaking (edge enhancement) in Live View for easier manual focusing, a camcorder carryover feature that I consider essential in all still cameras today, and retains the Pentax tradition of an interval shooting feature, another capability that I think should be in more cameras. And AA-battery devotees will be pleased to know that you can still buy an optional AA holder; given how poor the rated battery life is with the provided Lithium Ion battery, it looks like it might be imperative.

Given how much the K-30 encroaches on the K-5's territory, and with its superior video capabilities (though it's not clear whether it has manual exposure in video), I'd say there isn't much reason for the K-5 to exist. Perhaps a replacement is imminent. And it definitely looks like an improvement over the K-r. The one bewildering choice is that it's not shipping in a kit with the water-resistant version of the 18-55mm lens. That would likely bump the price over $999, but it's something buyers should be aware of.

I think the rugged design fills an underserved niche in the sub-$1,000 dSLR market. The 60D is pretty old at this point, but that's the reason its price puts it in the same competitive space -- if/when Canon replaces it, the new model will likely cost around $1,299 based on history. The D5100 is also ready for upgrading, but I don't think Nikon will bring out anything as compelling as this to replace it. The A65, however, offers some real competition. It has better video options and an articulating LCD; the K-30's construction might trump both of those if you're an outdoorsy type, though.
