var fovMax : float = 180;

var fovMin : float = 1;

var sliderPos : Rect = Rect ( 10, 10, 300, 30 );

private var camFOV : float;

function Start () {

 camFOV = camera.fieldOfView;

}

function OnGUI () {

 camFOV = GUI.VerticalSlider( sliderPos, camFOV, fovMin, fovMax );

 if(GUI.RepeatButton(Rect(Screen.width/2 -19 , Screen.height -50, 18, 18), "+")){

     camera.fieldOfView = 21f;

 }



}

function Update () {

 if (!Mathf.Approximately (camFOV, camera.fieldOfView)) camera.fieldOfView = camFOV;

its acutally really easy, since you have the camFOV var, just go

if(GUI.Button(Rect(10, 10, 200, 25), "Reset"))
     camera.main.feildOfView = camFOV;
