Is it possible that all "89b" filters are not created equal? Which reminds > me, where did you get your 89b filter?

I guess it's very much possible. I bought mine from Harrisson & Harrison. The build quality of the filter is not as good as that of Hoya, but still works for me. They manufacture filters in their own lab (sounds a small company). Therefore it's possible that it's not actually 89b (They called it 89b so I call it).
