Pentax has announced two new camera bodies:

• K20D is an update of the ”enthusiast-model” K10D, where the most notable new feature is a newly developed 14.6 MP sensor from Samsung.
• K200D is an update of the “entry-level-model” K100D. However, features-wise this new camera is very close to the present “enthusiast-model” K10D.
