For anyone deciding to invest in the FX-N... When it first came out it had no internal bayonet mount, so you wouldn't be able to put a filter on. I was just looking at a new one today in ebay that now has the internal bayonet. So it is something to watch out for, as there is another one in ebay without the internal bayonet. The filter size for the FX-N is now bay 4.
