yes its obviously a problem with bigger cards.. both with camera not coping with them and card readers.. but in my case it was the card reader that wouldnt go over 256 meg..
my camera is the panasonic FZ20.. now exactly what size card it will cope with i dont know.. but it does handle 512.. ???
this is definitely something that has to be gone into before folks go out and buy the currently available larger cards..
