UV- or Clear Filter for FUJINON XS8X4AS-XB8
 

Hi:
Got me this fantastic wide-angle lens FUJINON XS8X4AS-XB8.
Now I wanna protect it from damage like "flying dirt & gravel" with some UV- or clear filter. In the Fujinon-booklet they say that filter diameter is 107 + 1. Following this info, I bought such a filter - but it does not fit. Now I need some help and advise in this matter.
Please save me!!!
