Same thing happens with the EP-1. Profiles are only created when files are converted with ACR 4.6.
This only happens with the kit lenses. Regular four thirds lenses, and lenses which use an adaptor work as expected.
This seems to be to do with changes to the dng format recently -- such as the software corrections for lens abberations.
Thanks very much Robert - now I know that it is happening not just to me -that there is not something wrong with my software set-up. I had sent an email to Xrite some time ago but haven't received a response (not a biggie since it's not a showstopper problem etc.). It will be interesting to see if Xrite or Adobe make changes in the future to get around this problem, as I would imagine that as more cameras utilize the new dng format capabilities, then more users would be affected in a similar way.
