"When testing this script, after the player respawns the camera will zoom in from the last location where the player respawned from instead of from the camerapart of the respawned player. How can we fix this issue?"

The issue arises because we're not updating the camera's position when the player respawns. We can fix this by adding a listener for the character's Humanoid.Died event and update the camera's position accordingly. Here's the updated script:

```lua
-- Local script 
local player = game.Players.LocalPlayer
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local TweenService = game:GetService("TweenService")
local camera = workspace.CurrentCamera
local zoomedIn = false
local defaultFieldOfView = 70
local zoomedFieldOfView = 20
local zoomOffset = Vector3.new(0, 3, 0)
local zoomSpeed = 0.6

local cameraPart = Instance.new("Part")
cameraPart.Transparency = 1
cameraPart.CanCollide = false
cameraPart.Anchored = true
cameraPart.Parent = workspace

local function setUpCamera(character)
	local humanoidRootPart = character:WaitForChild("HumanoidRootPart")
	local humanoid = character:WaitForChild("Humanoid")

cameraPart.Position = humanoidRootPart.Position   zoomOffset

RunService.RenderStepped:Connect(function()
		if zoomedIn then
			cameraPart.Position = humanoidRootPart.Position   zoomOffset
		else
			cameraPart.Position = humanoidRootPart.Position - zoomOffset
		end
	end)

-- Update the camera's position when the character respawns
	humanoid.Died:Connect(function()
		if zoomedIn then
			cameraPart.CFrame = CFrame.new(cameraPart.Position, humanoidRootPart.Position)
			camera.CameraSubject = cameraPart
		end
	end)
end

player.CharacterAdded:Connect(setUpCamera)

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.Z then
		if zoomedIn then
			local zoomOutTween = TweenService:Create(camera, TweenInfo.new(zoomSpeed), {FieldOfView = defaultFieldOfView})
			zoomOutTween:Play()
			camera.CameraSubject = player.Character.Humanoid
			zoomedIn = false
		else
			local zoomInTween = TweenService:Create(camera, TweenInfo.new(zoomSpeed), {FieldOfView = zoomedFieldOfView})
			zoomInTween:Play()
			cameraPart.CFrame = CFrame.new(cameraPart.Position, player.Character.HumanoidRootPart.Position)
			camera.CameraSubject = cameraPart
			zoomedIn = true
		end
	end
end)
```
This script now listens for the Humanoid.Died event and updates the camera's position to the new respawned location.
