Never used a filter on my Olympus, never had a mark on the lens either - even though it got bashed a wee bit.
Now.... my Nikon lens is worth considerably more than the Oly... worth putting a filter on as extra protection... or just be careful? As its 16mm at the wide end I have to be careful that a filter would not get in the way too.
Pretty sure the lenses are pretty well coated anyway and scratches are rare...
But nice to get CS thoughts on the matter!
