Pentax K-x – Introduction

Although the Pentax K-x is based on the same design as the K-m, it actually inherits a number of features from the high-end enthusiast-level K-7. These include an 11-point AF system, in-camera HDR and HD video capture.

When we reviewed the Pentax K-m in AP 6 December 2008, we awarded it a score of 75%. While this is a good score, it lost some marks because we felt its performance lagged behind that of other entry-level cameras. Hopefully, Pentax will have made improvements in these areas rather than simply adding a few new ‘glamour’ features to appeal to the entry-level photographer.
