Why are you shooting RAW + DNG. DNG is rubbish, a waste of disk space. If you must shoot RAW + Jpg.>sRGB or AdobeRGB
If you are shooting in RAW then you set this when you export your file from the processor of your choice. Adobe RGB is really only useful if you are exporting for high quality colour glossy magazines, even then you should check with the publication's production manager. For Fine art printing I don't know, ask your printer. For everything else and definitely for on screen display you should use sRGB.
