The correct answer is both yes and no. The original camera cannot use more than a 2gb card. However there is a firmware update from the company that will allow the camera to use larger 4gb cards. So the question is whether you have the latest firmware in the camera... If not you need to install and then you can... if you are afraid to try to upgrade the firmware then just stick with 2gb cards. Odds are if you haven't upgraded the firmware then it is probably limited to 2gbs.
