As expected, Pentax has announced updates to its two popular and successful DSLRs—the 10.2 MP K200D (below, shown with the new 18–55mm II lens) replaces the entry-level K100D, and the K20D (above, shown with the 16–50mm lens) replaces the mid-level K10D. Both have 12-bit color depth, available vertical grips, and dust-busters. The K20D has live view, and although shooting speed is an adequate 3 FPS in RAW mode, it's stated to be an astonishing 20 FPS when capturing small JPEGs (unless that's a typo). Presumably there are intermediate steps in between.
Doubtless of most interest to most people will be the K20D's sensor. Pentax has collaborated with Samsung to develop a 14.6 MP CMOS APS-C-sized sensor. Interestingly, Pentax says that the peripheral circuitry for each photodiode is a mere .13 micrometers thick per pixel, allowing the light-gathering area of each pixel location to be the same size as a pixel in a typical 12-MP sensor. Pentax states, "The larger photo diode gathers more light in a shorter time and therefore can respond more sensitively. As a result, the K20D is able to achieve higher sensitivity levels (up to 6400 in the expanded ISO mode). Also, there is a more direct light path to the pixels, allowing higher quality results from classic Pentax lenses."
Along with the new cameras come several new DA (digital-specific) lenses, including 200mm, 300mm, and 35mm Macro Limited (below) prime (single-focal-length) lenses, and a 55–200mm zoom.
UPDATE: Street price should be around $1300.
