Personally, I would put a UV or clear filter on it to protect the glass from scratches and from the elements. It's also easier to clean a good UV filter than it is to clean the front element of a lens.

I use B+W MRC UV filters on my prime lenses (12/2.0 and 45/1.8). I bought them from a US store for US $38.50 each.

On my cheap zoom lenses (14-42 IIR and 40-150 ED), I don't bother with filters.

Make sure it is a good filter with multi-coated surfaces. Otherwise you might get flare.

The main objection to putting a UV filter on your lens is that it degrades image quality, the theory being that any glass placed in front of a lens will reduce its sharpness. In practice, this is true for cheap filters. However, good multi-coated filters do not have any practical effect on image quality.

Here is a good link with lots of comparative reviews on UV filters:
