Distance between player and his camera is too much

When I use mouse my (default)camera is rotating around the point which is not under camera, but around a point which is far from camera.
Which setting regulate the difference between position of default camera and position of player?
Where can I find this setting?

Most likely its the CAMERA BOOM or the official name SPRING ARM. Take a look here for more information. I hope this is what you are looking for… if not, please add some more information…if this is good, please mark resolve.
