What Sony Cameras Have Dual Card Slots?

While most photographers only ever use one memory card slot in their camera, there are some advantages to having dual card slots. One advantage is that it allows you to have an immediate backup of your photos in case one memory card fails.

Another advantage is that you can choose to have your photos automatically saved to both memory cards, or you can save them to one memory card and use the other memory card for overflow storage.

If you’re a photographer who often finds yourself shooting in demanding situations where every photo counts, then having dual card slots in your camera can give you some peace of mind knowing that you have a backup of your photos.
