Hello everyone, I want to start off by saying that I'm new to the digital world, I just purchased a Canon S1 IS. I looking to get another CF card and wanted some info about the different types and speed. With the camera I do have a 32 card, I also purcashed a 512 Kingston. I was thinking about getting another 512 or a 1gb card. I'm really lost about the speed of cards and which ones are better then the others. I'm using the carnera for sport and pictures of family and friends, also scenic pictures. I know that the speed factor is the best thing for taking sport shots. Thanks in advance.
