I have been trying to zoom in on this part and I cant here is some of my code, I put it in a local script in
local tween = game:GetService("TweenService")
local part = game.Workspace.ZoomPart
local camera = game.Workspace.CurrentCamera
goal = {}
goal.CameraSubject = part
local tweeninfo = TweenInfo.new(4)
Tween = TweenService:Create(camera, tweeninfo, goal)
Tween:Play
There are no errors

You need to change the CameraType to Enum.CameraType.Scriptable.
You should tween the Camera CFrame not the subject.
Also Tween:Play should be Tween:Play()
