Congratulations -- the Fuji S5Pro has plenty of "soul" so likely the IS version has as well
You might even pull off the occasional visible-light shot with it when combing a UV/IR cut filter and BG-38 or similar (to restore some of the colour balance).
As it draws on an original D200, it handles most F-mount lenses with ease. You need to trick modern E lenses away from their wide open state if stopping down is required, though.
