I convert all my RAW files to DNG. Initially it was a great way of
recovering space as the E-1 images weren't losslessly compressed. Now
with the E-3 and my other cameras I just keep it like that as a matter
of habit. There are some bonuses with DNG - particularly the absence
of sidecar files that one gets when using some RAW editors.
If you're not using Olympus's own RAW editor there probably isn't any
reason to convert. However, the editors I use (Lightroom, Photoshop)
will be converting the ORF file anyway in order for me to edit it, so
I may as well keep it in DNG format. I would think DNG would outlast
proprietary RAW formats in the longer run - so long as Adobe don't go
out of business...
