Mark, I don't think the main problem is in the conversion. Neither RSE or Pentax Photo Browser can open the main raw image, though the Pentax program will show the Jpeg thumbnail. I think there was a glitch either in the camera when the original raw file was created or when the file was copied. ACR just seems to be of middle sensitivity, not failing when trying to load the file but getting screwed up by the bad data. Raw Therepee can open the DNG you posted but no other program I have that will convert raw files can actually read the raw data, om either the PEF or DNG even though most appear to open the embedded JPEG.
