using UnityEngine;
using System.Collections;

public class abc : MonoBehaviour {

	public float zoomSpeed= 250;
    public float zoomMin= 5;
    public float zoomMax= 80;

 
    void Start()
    {
       
    }
 
    void LateUpdate()
    {
   
        float scrollwheel = Input.GetAxis("Mouse ScrollWheel");
		
		if (scrollwheel > 0)
		{
			camera.fieldOfView -= Input.GetAxis("Mouse ScrollWheel") * zoomSpeed * 0.01f;
		 
		 camera.fieldOfView = Mathf.Clamp(camera.fieldOfView, zoomMin, zoomMax);
		}
		if (scrollwheel < 0)
		{
			camera.fieldOfView -= Input.GetAxis("Mouse ScrollWheel") * zoomSpeed * 0.01f;
		 
		 camera.fieldOfView = Mathf.Clamp(camera.fieldOfView, zoomMin, zoomMax);
		}
	
}

Here is a bit of a rewrite. zoomSensitivity is how much the scrollwheel will zoom per click. zoomSpeed is how quickly the zoom will lerp.

using UnityEngine;
using System.Collections;

public class abc : MonoBehaviour {
 
    public float zoomSensitivity= 15.0f;
    public float zoomSpeed= 5.0f;
    public float zoomMin= 5.0f;
    public float zoomMax= 80.0f;
	
	private float zoom;
 
 
	void Start() {
		zoom = camera.fieldOfView;
	}
	 
	void Update() {
		zoom -= Input.GetAxis("Mouse ScrollWheel") * zoomSensitivity;
		zoom = Mathf.Clamp(zoom, zoomMin, zoomMax);
	}
		
	void LateUpdate() {
		camera.fieldOfView = Mathf.Lerp (camera.fieldOfView, zoom, Time.deltaTime * zoomSpeed);
	}
}
