The verdict is that you should never add an additional element, to your already complex highly engendered lenses unless absolutely necessary. That said any glass will help subtract some UV. (I don't remember how much, or what wavelength). Use a mulitcoated filter, and one that doesn't add any color cast unless you want a special effect, so a multicoated, plain glass filter is best.

Filters?
I need to buy one for my 16-50 seeing the time I spend in sandboxes
with my camera these days... a blower wont do the trick for me all the
time.
Thanks

I come from the capital K Klutz school of carefulness. Starting with the
10D, I've been putting Giottos Aegis screens on the LCDs. It's a lot cheaper
to replace if (when) something goes wrong.

I'm also one of those who typically puts a UV filter in front of the lens.
When I dropped my camera bag in an airport, the only damage was some
cross-threading in the lens (which Eric fixed for me) and the replacement of
the filter (which had given itself up to save the lens).

fool, and he might possibly be a damned soul; but if he may not, he is not a 
free man any more than a dog.
