    that O is a 0
    It means it doesn't affect the colour balance, I'm pretty sure.

    I have not found reliable information about the (N) designation anywhere on the net. But (0) (zero) is the Wratten number for UV.

    There seems to be talk that N is just the same thing but it being a designator for Neutral rather then displaying the Wratten number.

    ^^^ dont by hoyas!! please save yourself the aggrivation

    they get dirty easily. and are near impossible to clean properly. youll wind up buying a better brand later on. guarenteed.

    ya there cheap and dandy for the average person. but if you plan on shooting a while as a continuous hobby. dont go with hoya.

    thats just like going with ebay slaves or pocket wizards.

    ebays are about $30
    PW's are about $150 per unit.

    ebays will not always fire and last maybe a year,

    PWS will fire everytime guarenteed, there durable and will last for years.

    Funny I have no problem with any of my Hoyas'. The N is for neutral, cant remeber where I found it but, I remember that.
