I own the Casio Exilim EX-2300. It shoots nice photos but there are 2 problems. When I go into the Continuous Shooting Mode, the megapixels available go to 2MP. I can't choose 4,7 or 10 MP, but only 2. Why is that? Is the camera too slow to capture a photo any higher than 2 MP? This means I must forego quality when using fast shooting. My other problem is that when I attempt to search for a shooting date, the camera freezes. I must remove the battery in order to use the unit. Why does this happen? I use a 4 GB HC SD Card.
