Dual card slots are a common feature on DSLRs, and the Canon 7D is no exception. This means that you can use two different types of memory cards in the camera at the same time.
This is great for taking photos and videos with different types of content, like photos and videos of your family while you’re out shooting photos and videos of the scenery while you’re out shooting photos. Plus, dual card slots make it easy to back up your photos and videos.
