You didn't give any specifics on what mount it was designed for but many Fujinon TV lens are C-mount. Here is a C-mount to Nikon adapter.
I recently acquired some zoom lenses from a T.V. camera. The lens is a Fujinon 14x Fujinon- TV ZOOM LENS .
Looking for a converter to use this lens on a Nikon Digital Camera D60.
If you need any more info please feel free to contact me.
