Polarizers on very wide lenses? Why do you feel you need one? Polarized light is very directional... so the wider a lens, the more variation you will get. Meaning, you will get very [color="#FF0000"]UN[/color]even skies, which will be very distractive.
And obviously... no filter can be mounted on this lens anyway. But the question remains: Why would you want to (pol-filter on 14mm...)?

If a user wants to use this lens on APS-C, then 14mm is not ultra-wide (equivalent to 21mm on film).
(This is a compelling lens in APS-C since most lenses of similar focal length are very slow or very pricey.)
21mm is a bit wider than I would want to consistently use with a polarizer, but I've been able to get pleasing results with a polarizer on 24mm lens (film), so perhaps someone with more skill or imagination or determination could find use for one on a 21mm (equiv.) lens.
Example 1, 24mm lens (on 35mm film) Portrait:

Yes, the sky is uneven in the second example. But by carefully positioning the clouds on the right-side of the yellow-line <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='
' /> I was able to somewhat mask the effect in the sky. More importantly, it cut the glare off of the road and foliage. Here is a the same scene without polarizer for comparison:

Getting back on topic, like Brightcolours I also have nothing useful to contribute to the original poster's question about how to mount a filter to it. But if using it with APS-C there might be a way (i.e. DIY trial and error) to mount a circular filter to a tube that slipped over the lens.
