Pentax has a long and storied history in photography, and now another marker has been laid down with the announcement of the K-1 , their first digital 35mm full-frame SLR body to actually reach market.
It will take some time for this new camera to become widely available, see extensive field use, be tested and compared at DxOMark, and have its attributes (plus perceived faults or shortcomings) dissected hither and yon, but I expect it to make quite an impact. One feature—Super Resolution Mode—is going to get a lot of play, and will be especially interesting to landscape (and perhaps close-up) photographers (see some discussion already here). DPReview also has an excellent short historical piece. Much more to come.
