Use Pentax software to convert to uncompressed DNG then adobe

It's all relative.  The K10D Pef file is actually smaller than the

How are you opening PEF files. My dng converter on the ibook is the

I'm watching the price on the Buffalo 2TB setup.  That's 1TB fully
mirrored (which is how I'll probably use it), or 1.5TB full RAID.

Not too odd.  Compression (of any kind) was only added at the
last minute; as little as a month before the final release of
the camera there was no compression of either format.

As a PEF is a private format Pentax were free to use any kind
of compression scheme they chose (working out what algorithms
they use is on my list of things to do). Compressed DNG has to
use the compression scheme called for in the DNG specification.

My guess is that Pentax implemented whatever they had the code
for readily available.  I expect to see DNG compression in a
later update to the firmware.

LOL ... of course, Mbytes were meant, not Gbytes.

I set the K10D for capture as RAW/DNG format. I run the DNG files  
through Adobe's DNG Converter, which does lossless compression and  
renders them to be 10-11 Mbytes apiece on my hard drive, down from  
the average of 16.2 Mbytes, with very little variance, on the SD card.

Similar captures with the camera set to RAW/PEF seem to vary a lot  
more, but are smaller. I get sizes from 8.5Mbytes to 14.5 Mbytes per  
file on the SD card. Using PPL to convert these to DNG, they grow to  
21 Mbytes apiece, which DNG Converter will then compress back to  
10-11 Mbytes.

Re: K10D RAW and DNG image size

[Rick Womer]

Oddly, the K10D compresses the PEF files but not the
DNG files.

My ist D produces ~13 MB PEFs.  My workflow is to put
the card in a card reader, and import pix onto the
home Mac as (losslessly) compressed DNGs using Adobe
DNG Convertor.  Those DNGs are 5-6 MB.

DNG is about 16mb. I haven't shot a PEF yet, as ACR doesn't support them yet
