It depends on the camera. They are all different and you need to look closely at the depth as it can affect the quality of the pictures. For this particular model, it was 50 feet. There are some that go to 35 ft or less. Also the clarity of the water and the lighting also affects things. I would tell you that I used this camera with snorkeling and it did a decent job at 20 feet. My pictures turned out and I love them.
