That particular Fuji model apparently is much better suited to IR anyway, as its UV response is claimed to be curtailed and reaches not below approx. 380 nm (Fuji specifications).
I have the Fuji S5 myself and it has been modified for "broad band" use. It does not go down as far into UV as the modified Nikons at my disposal, but is OK for near-IR and IR work. I use it largely for making simulated 'false-colour Infrared' for which purpose it does very well. All parts except batteries are compatible with D200, a fact I have availed myself of several times. For example, replacing a broken rear display with the one for D200.
The RAW files for these cameras (RAF) are a royal pain to process properly and Fuji's own proprietary program must rank among the worst written and designed software in history. SilkyPix Pro does a pretty good job of making the RAFs useful though, despite its share of idiosyncrasies, but is not free software.
