Lense adapter and extra lenses for fuji finepix...

Hi, I bought The E900 finepix, and it's very nice, but i'd like to buy some extra lenses, in order to get closer images from distant objects, i know the e 900 doesn't have any thread to adapt easily the conventional lenses, so maybe i'll need and adapter, and the lenses,
Could you help me please, to find out what kind (brand, reference...) of lense adapter and extra lenses i have to buy....
Thanks
Andres
