Just posted: our in-depth review of the Pentax K20D. The K20D is a fully-featured semi-pro DSLR available for the cost of some of the latest, upper-entry-level digital cameras. It adds a handful of features and tweaks to the highly-respected K10D and attempts to address some of its shortcomings whilst also incorporating a colossal 14.6 million photosites on a sensor co-developed with Samsung. Is this enough, given the quality of some of the competitors?
