I use a protective filter when the lens needs protection - particularly with macro shooting. It's just too physical - crawling on the ground, laying prone, twisting into odd positions - to not expect that sooner or later the camera will take a hit in the front element. More than one time I've closed in on bug to hear a tap and realize that some twig or stem, so close that it's invisible in the finder, has hit the front of the glass. I also use filters when shooting at the beach in the spray - cleaning sand off the front of a lens gives me the willies.
I use Pentax SMC filters, though I have a couple of Hoya HMC filters that seem to work just as well. I have not seen any problem with image degradation, though I haven't used the Hoya's much with the digital bodies. I used the Pentax filters for thousands of macro shots and saw not problems - they are a bit pricey though. FWIW - a really good, hard hood -not the soft rubber ones or the collapsible, built in kind - but a hard screw on or clamp on hood is usually as good as a filter.
