It depends. For every filter there associated a "Filter Factor":
http://photonotes.org/cgi-bin/entry.pl?id=Filterfactor For example, Hoya and B+W publishes their filter factor values: http://www.photofilter.com/hoya_factor.htm http://www.schneideroptics.com/filte...&_warming/ Please notethese values are their results under certain predefined testing conditions and light of certain bands of wavelength,they may have variation in practical use.

The difference is so negligible, just fit and forget.

The UV filter has essentially a 1x exposure factor. So just put it, shoot and forget. In any event, all (well, most anyway) metering is done through the lens, so any factor that does exist is automatically taken care of.
