The downside of a DSLR camera is that they can be expensive and bulky. They also require more knowledge to operate than point-and-shoot cameras, making them less user friendly for novice photographers. Another issue with these cameras is that the batteries tend to drain quickly, meaning you'll need extra batteries or an external power source on hand if you're out shooting for long periods of time. Lastly, due to their large size and weight, it can be difficult to carry them around when travelling for extended periods of time.
