K10 PEF's or DNG's

Dick, I see your point now though but not the usefulness of it.
Exif support, Image title, Person who created the image & Copyright holder so you're only missing keywords from your list. Only useful I believe when editing, don't think I'll ever input keywords while shooting.

My biggest problem with DNG is the compressing by the camera, it isn't that good. You can hold 50% more photos if you use PEF instead of DNG. Both of files are the same and camera gives the same information to both so the extra data space isn't used at that stage (I believe).
I convert my photos straight to DNG when uploading them with the pc, only 2 reasons behind that, smaller file and better support by Adobe software.

Hi Stefan,

Oh I may have misled you - I always shoot PEF in the camera (not DNG)... Then convert to DNG with Adobe DNG converter during the download process. Idimager does that automatically. Also, I have Adobe DNG converter replace the jpg preview image in the raw file with a full size preview as well. And surprisingly, the resulting DNG is smaller than the PEF in spite of the larger imbedded preview. I guess the Adobe RAW lossless compression is more compact????

Hi Dick,

Sorry that I thought that the topic was camera specific so thought it only went what the camera did. I only have DNG files on the pc now, i use lightroom it uploads and converts to DNG since I've also photoshop lightroom directly link the DNG to PS and PS have no limitation handelling those RAW files.

I think that for the speed the camera doesn't compress them as much, pc has also a lot more power to compress those files.
I do wonder why DNG is so much larger then PEF that the camera makes.
With the K10D i do notice that it process DNG faster, i can shoot 2 or 3 frames more before the buffer fills but I would rather have them smaller, I've never filled the buffer with actual shooting.

I don't think Paint Shop Pro Photo supports PEF in the standard version.
