<p>Since the launch of the K-7 in 2009, Pentax's flagship, enthusiast-grade APS-C DSLRs have been among our favorites. After a couple of evolutionary models, the brand-new Pentax K-3 has arrived, and it's a revolution in the making. Not only does the K-3 bring significant changes inside and out, it also includes an industry first. The K-3 is the only SLR to feature on-demand low-pass filtering, which lets you choose whether ultimate resolution or resistance to moire are more important for any given shot.</p><p>And there's plenty else besides that makes the Pentax K-3 an exciting upgrade, including a brand-new body that retains the spirit of the design first introduced with the K-7, yet makes significant changes to the controls for the first time in several generations. The 24.3-megapixel Pentax K-3 also sports significantly higher resolution, and yet thanks to a new PRIME III image processor, shoots faster and longer than ever -- a whopping 8.3 frames per second for as many as 60 frames. And despite the significant resolution increase, the K-3 still offers a maximum sensitivity of ISO 51,200 equivalent.</p><p>The Pentax K-3's revolutionary new on-demand anti-aliasing system arrives alongside 27-point autofocusing, and 86,000 pixel RGB metering systems, making for one heck of a package.</p><p>Pentax has also gifted its newest APS-C flagship with a brand-new 86,000 RGB pixel metering sensor and a much more capable 27-point autofocus sensor. All but two focus points are cross-types, and three of them will work to f/2.8. The Pentax K-3 also boasts double the shutter life of its predecessor, an improved image stabilization system, a brighter pentaprism optical viewfinder with greater magnification, and a larger, higher-resolution LCD monitor. Storage and connectivity options have been refreshed, too: the K-3 provides dual SD card slots with support for high-speed UHS-1 cards, boasts a much more up-to-date movie feature set, and sports a brand-new USB 3.0 SuperSpeed data connection.</p><p><a href="http://www.imaging-resource.com/news/2013/10/07/pentax-k-3-review-first-impressions-enthusiast-dslr-optional-anti-aliasing">Keep reading...</a></p>
