I didn't check back that far in threads to see if this has already been addressed so sorry if it has. But it looks like Elements 7 hasn't updated to process K7 PEF files.
I have never really play with DNG files but they work fine as far as I can tell. What is the difference in the two PEF-DNG? Is DNG fine or do I need to upgrade to different software. I really don't want to do that because of the cash I just sunk into the K7 and a couple other lenses.

Thanks

DNG is an industry standard. I see no need to use PEF.

Elements 7 does not recognize K7 PEF files as the camera did not exist when the software was launched. You just need to update the RAW converter (ACR) within the software package. The update can be downloaded free of charge from Adobe - Latest Product Updates

In terms of image quality there is no difference between DNG and PEF

PEF is the pentax proprietary RAW format. DNG is an open RAW format that was created by adobe but could be used by anyone.

there should be no quality differences between the formats, and unlike JPEG's, which are created after post processing the RAW file a DNG is not processed.

i don't usually shoot RAW (i have my own, good reasons for this) but if i did i would definitely save DNG's rather than PEF's because DNG's will be supported as long as adobe is around. PEF support on the other hand is not guaranteed and gets complicated with different versions of the format (different cameras, different firmware versions, etc).

i just found out that none of the big players, nikon, canon, or sony have native dng support which is too bad because consumers would benefit from a single, well supported raw format.

Isn't DNG just Adobes version of RAW software? I don't think it is anymore of a standard than anything else.

It's an Adobe standard - that's about it. Proprietary to Adobe rather than a camera manufacturer. They may freely license its use but that doesn't make it a standard, never mind an open one.

Given that some of us use Adobe PP software and think they'll continue to support it, we hope that we're not looking for an up-to-date .PEF raw converter in 15 years.

When I got Elements v6, I had to get the (free) newer ACR for it to recognize that camera. Simply put the file in the "plugins" directory.

PEFs are slightly smaller than DNG, and obviously the Pentax software, as well as Elements, Fastone and others open it just fine, so I would not worry about it being obsolete anytime soon. You can also simply convert them in a big batch if needed.
