I shoot DNG exclusively (though I usually run the files through DNG Converter when downloading because I can have it do file renaming at the same time and it gets me to the latest spec DNG) for 3 reasons, in increasing order of importance: 1 - Files are smaller than PEF 2 - The open format of DNG (it's based on TIFF) is better for future compatibility than almost anything else (except possibly TIFF itself and JPEG) 3 - The embedded MD-5 hash makes file validation possible en mass, that is to say, without opening files and looking at them. (This final item is largely why the Library of Congress adopted DNG as its archiving format.) -- Mark Roberts - Photography & Multimedia www.robertstech.com
