True, filters can subject a lens to flare, particularly uncoated filters.
But with flare controlled by use of a lens hood, I doubt the use of any
decently made filter (UV/skylight/haze, polarizer, color correction and
similar "clear" filters) impairs resolution in any way. A high quality
polarizer or neutral density filter is more likely to be neutral and not
influence color in an undesirable way.

I have proven to myself that filters increase flare, and uncoated filters
are
the worst. With no filter on the lens and the camera pointed at a bright
light source and framed such that the source is in one corner of the
viewfinder frame, you will see some flare. Take a filter and screw it on
the
lens while you are looking through the camera. You will see a "wobbling"
flare patch as the filter turns...Try a different filter, the flare changes
color. Try a MC filter, less flare, maybe none.
In theory, a filter *must* degrade the image. How much depends on several
factors. Whether the degradation is noticable also depends on many things.
Only use a filter if you have to. I have become a big fan of my B+W
polarizer. I don't use UV filters though.

My opinions may have changed, but not the fact that I am right.
