A lot of dogs will not look at a camera (especially a large pro camera with a lens on it). The lens looks like a big scary eye and they don't really like it. Rather than trying to get her to look directly into the camera, try to get her to look just above the camera or just over your shoulder. Get your shot all set up and then either squeak a toy or throw a toy back over your shoulder. That will usually get them to look - especially throwing something.
