Almost 16 months after the launch of K10D, Pentax announced the new K20D, its mid-level DSLR (top of the Pentax DSLR line) with some new features. Physically the new K20D is almost identical to its predecessor. The biggest improvement over the K10D is the new 14.6 MP CMOS image sensor, which offers the highest resolution in an APS-C sized sensor and known to be co-designed with Samsung and used also in Samsung GX-20.

What is new in K20D?
With the new sensor, K20D presents ISO 6400 sensitivity which doesn't exist for K10D. The question is, with the increased pixel density of the new 14.6 MP sensor, how will the K20D cope with the high noise levels associated with the decreased pixel size. There are some other improvements like the addition of an X-sync socket that will really benefit studio shooters, dust alert system that identifies the location of dust building up on the sensor, and the ability to calibrate the colors on the screen to more accurately reflect the output and make better judgement while shooting.
While these changes may be important for some users, the weakest points of K10D for most the users like the poor JPEG output, slow AF performance especially under low-light conditions and relatively slow continious shooting speed of 3fps unfortunately seems to be unchanged. on the new K20D Well it is hard to tell before seeing the first real life reviews of the camera, but until then they will stay as a question mark in potential buyers minds.
We prepared a technical comparison table for the K10D and K20D to at least give an idea for the potential buyers of K20D, inorder to better decide if the technical improvements are worth the price difference.
