Answer
(Ver.3.0.0.5) is included with the SILKYPIX Developer Studio 3.0 for PENTAX.
SILKYPIX Developer Studio 3.0 for PENTAX is a software and make color adjustments to expand it (development) develops the RAW file and saved in TIFF format or JPEG. RAW files can be handled by this software is only DNG files taken in and Q K-30, K-01
Quote: Image of K-30 Can I use a Digital Camera Utility4?
Answer
RAW image editing and deployment is not compatible with JPEG images can be viewed.
Interesting that you can only use the bundled K-30 software to open RAW files shot with the Q, K-30 and K-01.
And PDCU 4 - as supplied with the K-5, Kr, Kx etc - can't open K-30 RAWs - only K-30 JPGs.
Looks like Pentax will be moving forward with Silkypix Developer Studio in future, rather than PDCU 4.
