Object gets too far away from cinemachine Camera

So i’m making 3D airplane game i move it through Script using “transform.position” and my Cinemachine camera following the airplane but when i set the plane speed to small values like 10 the camera zooms in and when making big values like 100 the object starts to get far away from my camera is there is a way to stop this effect?
