I am trying to set a player's camera to look far away from a part. Is there a way I can just focus on a part, lock in on it and zoom it out as far as I want? I tried it, but it only focuses on the part. It doesn't let me change how far it is from it.

local cam = workspace.CurrentCamera
cam.CameraSubject=workspace.Part
cam.CoordinateFrame=CFrame.new(10,10,10)
cam.CameraType = "Attach"

I have looked at the wiki and it only showed me how to set where the camera is looking. I cannot change where the camera is. It just stays far away.
