I capture in RAW/PEF as that is compressed and save space on the card.
I import PEFs from the card with Lightroom using "copy files with DNG  
conversion", putting them on the hard drive.

If you capture using RAW/DNG in camera, you can compress them on the  
fly to your hard drive by using DNG Converter to move them from card  
to computer. Lightroom does not do the compression when it moves a  
DNG file, it assumes that it is fully formed and needs no conversion.
