First of all, in my opinion, the fuji line is not strong. The only decent camera they actually released is the f410. Even their S2 is stupid, they just copied the nikon f80 body, strapped in some double A batteries, and charge 250 bucks more than the D100. The fuji line doesn't compete with the canon/nikon/olympus (only higher end in olympus). If your debating between fuji and sony, although I don't really love either of the two companies. I would go for sony no question.
If your looking to get a higher end model in sony, go with the f717. Absolutly amazing camera. If you don't have the bucks for that, the olympus C-5050 or the canon g3 are probably 2 of the greatest camera's out there right now.
If your looking to get a lower end model, go for the Canon A70. Really nice camera for the dollar value.
