K20D PEFs are smaller the the DNGs it produces. It also gives wildly
inaccurate image space estimates available on the card in DNG mode as it
uses the average size of PEFs to calculate space.

John -
I shot PEF's on my *ist-D and K-10D as well. My workflow eventually
was to run them through Adobe DNG converter before editing and then
discard the PEF's and work form the DNG's only. The *ist-D only
offered PEF RAW files and and the K10D offers DNG's but they are
uncompressed - I found it was better to shoot smaller PEF's, save
space on the memory card, and then convert. The DNG's from ADOBE DNG
converter could be much smaller than either the PEF's or the K10D
DNG's. I don't know for the K20D since I have never used one.
If you want DNG raw files and also to optimize drive space you might
want to use the DNG converter for the K-10D files. Some time ago I had
a mini project of converting all PEF's to DNG's and freed up what at
the time was a lot of disk space.
Like I said, don't know about the K20. You can test file sizes easily,
of course.

It was originally my question.
In 2004 I shot a combination of JPEG, medium size TIFF and a very few
PEF
(RAW) files with the *ist-D. From 2005 - 2012 I shot PEF or PEF+JPEG
with the *ist-D, K10D and K20D.
At the beginning of 2013 I switched my RAW format to DNG for the K10D &
K20D.
I had the idea that it might simplify my life if I used Adobe's
stand-alone DNG converter to convert all the old PEF files to DNG.
I was curious whether after the DNG conversion I should keep *BOTH* the
PEF files *and* the DNG files, or keep just the DNG files.
