Photoshop & EXIF data

I'm busily using Nikon View & PS CS to convert my masterpieces
to jpeg from RAW. I notice that while PS keeps some of the EXIF data it discards what I consider important info like the lens used to take the pic. I'm guessing PS doesn't know about this whereas NC does. Is this correct or is there something I can do in PS to keep it?
TIA
