Ive been using a 1 GB Jessops CF card in my 350D since i bought it new 3 years ago. recently the camera has been having problems taking photos!! (which is a slight problem!) sometimes there will be a long delay, 3/4 seconds, between autofocusing and taking a shot. In manual, it just wont take a photo!! however when i take to CF card out the camera is quite happy and will snap away. obviously its a problem with the CF card. has anyone else experienced simular problems? are some CF cards faster/better/different?? which one should buy? thanks. pat
