Pentax K-x review

Dynamic range

Our tests show that the Pentax K-x has a dynamic range of around 12EV. This is a good score and matches many other more expensive cameras. In use, though, I found that the lower midtones are a little dark. However there is an in-camera solution.
Like most other digital SLRs, the K-x has highlight and shadow correction features. These do not affect the dynamic range, but they do reduce the brightness of highlight areas and lift shadows.

If you are taking images that you don’t wish to spend too much time editing before printing, it may be worth leaving these settings turned on. However, the shadow correction can introduce noise in shadow areas, so I would recommend using it only at low ISO sensitivities.
