Download a full version of the well-regarded DxO Optics Pro RAW processor/image editor (v6) for free, courtesy of DxO and the German 'Fotohits' magazine.
Steps:
Follow the
Promo Link
Enter you email address
Press "BESTÄTIGEN"
You will then be taken to the download page for the Windows and Mac version of DxO v6.
(NB: The promo and download pages are in German).
The latest version of DxO is v.8, but this older v6 fully supports the following Pentax camera bodies:
Pentax K10D
Pentax K20D
Pentax K200D
Pentax K-5
Pentax K-7
Pentax K-m
Pentax K-r
Pentax K-x
as well as lots of Canon, Nikon, Sony etc bodies too, which are listed in
this PDF (28k). As this is the Elite edition, some full-frame bodies are also supported.
Bodies later than the above Pentax models (K-30, K-5IIs etc) will still work, as DxO v6 will still open DNG's (and perhaps PEFs) from later Pentax bodies.
This v6 also appears to allow you to download and use all of the appropriate DxO lens modules created to date, which means the 30 or so DxO modules for Pentax lenses should also work with it.
A great opportunity to try out DxO if you haven't used it before. An upgrade deal to DxO Optics Pro v8 is also available on the download page.
