Camera drifting away when only rotating?

Question

I have this script attached to the camera:

 void Update () {
     transform.LookAt(Vector3.zero);
     transform.Translate(Vector3.right * Time.smoothDeltaTime);
 }

But when the game runs really long the camera is further away. I noticed this yesterday when I had a test build running in the background. The object it was rotating around got really "small". Today I went AFK for a couple of hours and it was even smaller.

I guess it is because I actually move the camera on it's local axis and since it has a lookAt target this axis changes. But it is not rotating 100% correctly. It is not causing real problems but is there a fix to it?

If you wan't the camera to rotate around a point, you could, amongst other possibilities, set the position with trigo :

 transform.position = point + new Vector3( Mathf.Sin(Time.smoothDeltaTime * speed) * distance, height, Mathf.Cos(Time.smoothDeltaTime * speed) * distance);

Then tweak speed, distance and height to get it right.
