It doesn't matter what camera you have, any camera can work with any photoshop. I would advise picking up cs2 for it just because you really don't need cs3 or 4 and its cheaper. Are you thinking of buying it? Also make sure you install camera raw and the correct version so you are able to process raw photos. If you have any other questions feel free to PM me.
