3rd person zoom

im trying to kind of make my game like ghost recon where you are in 3rd person but you can zoom into your scope on your gun with a button? could I get some help?

In every selectable weapon’s model prefab, you could have an empty gameobject that is positioned exactly where you want your camera to be when aiming dowm sights, and then lerp the camera from its original position to the position of that transform whenever the player aims down the sights.
