Does this FW correct something you need or do? If it doesn't you may not even see a difference in camera operation with the FW update. If it has a bunch of bug fixes it is well worth doing but find out what it does first.&nbsp;</SPAN></P> <P><SPAN>Did you format the SD first and then load the FW file on it?
