Ich habe mit der K-5 zwei Aufnahmen gemacht in RAW+ und in PEF und DNG und anschliesend die MetaDaten mit EXIFToolGui exiftool-Version 8.91 ausgelesen. Der Bilddateninhalt scheint meines Wissens in beiden Formaten identisch zu sein.
Die Maker Notes zwischen PEF und DNG sind identisch - deswegen hier weggelassen
Hier die PEF Meta-Daten
