Hi, I have heard people discuss how the newer fd's show noise sooner than the older models........does anyone have any advice they can give me? I have the opportunity to purchase an f20, but really wanted a slimmer camera. Do you think that Fuji will come out with a camera in the near future that will be as great as all the f31fd owners say they are? Should I get a used 31 or 20, or wait on a newer model? Any advice or experience would be appreciated!
