Unity3d move camera using mouse wheel

I am trying to make simple product visualisation. And I want to zoom or move camera towards the object. My code looks like this:

    public class mouseMover : MonoBehaviour {

        public Transform target;
        public float speed;


        void Update () {

            if (Input.GetAxis ("Mouse ScrollWheel") < 0) {
                float scroll = Input.GetAxis ("Mouse ScrollWheel");

                transform.LookAt (target);
                transform.Translate(0, 0, scroll * speed, Space.World);


            }

            if (Input.GetAxis ("Mouse ScrollWheel") > 0) {

                float scroll = Input.GetAxis ("Mouse ScrollWheel");
                transform.LookAt (target);
                transform.Translate(0, 0, scroll * speed, Space.World);
            }

    }

}

But when I try to zoom, it just "fly" around the object and when camera get on the another side of object, it starts to recede.

It's because you use Space.World instead of Space.Self :

void Update ()
{
    float scroll = Input.GetAxis ("Mouse ScrollWheel");
    transform.LookAt (target);
    transform.Translate(0, 0, scroll * speed, Space.Self);
}
