The Casio has worked out very well for an extremely small camera that can be carried with me at all times. The SD card I bought with the camera is 1 gig (the max. Casio sells) Nowhere in the specs does it list the max. card it can take... so I just purchased a 4 gig card which the camera *cannot* recognize... though the card tested good. Fortunately I can return the card less a small restocking fee...but wonder if anyone has tried the camera with a 2 gig card?
