Ok, so I thought it was time I made the switch to raw so I was fiddling the settings on my camera (Pentax K-m) and I found out it lets me choose 2 types (formats?) of raw: PEF and DNG. Now which one does Lightroom like (I suppose only DNG?)? I tried to look this up through Google but can't figure it out. Help!

Also, I can choose from 3 different formats on my camera, JPEG, raw and raw+. I checked my manual but there's nothing about raw+, does anybody have any information about that?
