Raw format: DNG vs PEF

[Wazza999]

Do any Pentax sages out there have comments about using the Pentax specific PEF format for raw files compared with the generic Adobe DNG format? I've always stuck to DNG - no trouble with raw converter updates etc. etc., but from time to time have heard comments about the benefits (?) of conversions from PEF.

I use PEF and DNG from the Pentax 645D, the only thing about the PEF is that colours are slightly different, dare I say more accurate when opening and viewing them as Raws - such as the white balance, a bit warmer too.

DNG has its smaller size advantage also.

PEF is smaller than DNG on K7 and K5 I'm surprised by the 645D having smaller DNGs

Canon RAW CR2 files when converted to DNG is about 1/2 to 3/4 the size of the original CR2 files in my experience also.
