Pentax K-x review

Our verdict

With competition very fierce in this sector of the market, it is perhaps no surprise that the K-x comes in a choice of four colours, including a bright red that may attract a few more fashion-conscious photographers than the dowdy, conservative black we are now used to. In Japan, the K-x is actually available in 100 colour combinations.

However, the K-x is far more than a fashion accessory, as the improvements over the K-m are worthwhile. There are numerous in-camera options and settings, and certainly enough to keep someone learning photography interested. It should also be considered as a back-up DSLR for the K20D and K-7, especially as it features video capture. In all, it’s a great little DSLR with just a few areas in need of improvement.
