10MP DSLR Shootout: Pentax K10D27075121508PentaxK10DThis pleasant surprise combines an assortment of goodies -- built-in image stabilization, self-cleaning sensor, easy-to-use image controls -- in the beefiest, best-sealed body of the bunch. System flexibility: Pentax has an ample current lens catalog, and given its legacy as one of the earliest players in 35mm SLRs, there is a huge stockpile of older lenses that will work on the K10D to some degree. And you can use any of them with image stabilization, as the K10D allows you to enter the focal length of an older lens so it works properly with the camera's sensor-based Shake Reduction system. Plus, the Pentax AF360FGZ and AF540FGZ accessory flashes provide wireless TTL operation. Rank: 3 tie. Control: The K10D doesn't have quite the smorgasbord of shooting and editing options of the Canon or Nikon, but still offers plenty. Besides sliders for saturation, contrast, and sharpness, there's a two-axis graphic control for fine-tuning color balance; white-balance presets include three varieties of fluorescent lamp. After the shot, you can apply a variety of digital filters. You can manually select one of the 11 AF points or have the camera select it -- and, yes, that's accessed via an external dial control, too. The built-in flash, though, won't function as a wireless flash trigger -- you'll need two accessory units for wireless operation. Rank: 4 tie. Ease of use: With its ample gasketing and sturdy construction, the K10D is the biggest and heaviest of the test cameras (though it's neither terribly big nor awfully heavy). The upside is its excellent ergonomics, with a well-located shutter button, front and rear command dials, and jog dial. The K10D parts company with entry-level Pentax DSLRs in giving access to far more adjustments through external controls instead of menus.
