Camera.CFrame won't loop through multiple cameras for my menu GUI?

I'm trying to loop cameras for my menu GUI with multiple camera parts, but it won't work, any help please?

local camera = game.Workspace.CurrentCamera
local Player = game.Players.LocalPlayer
local menu = game.Workspace.MenuCamera

local Char = Player.Character or Player.CharacterAdded:Wait()
Char:WaitForChild("HumanoidRootPart").Anchored = true

local function camerastuff()
	camera.CameraType = Enum.CameraType.Scriptable
	camera.CFrame = menu.Cam1.CFrame
	wait(2)
	camera.CFrame = menu.Cam1.CFrame
	wait(2)
end

game:GetService("RunService").RenderStepped:Connect(camerastuff)

script.Parent.TextButton.MouseButton1Click:Connect(function()
	camera.CameraType = Enum.CameraType.Custom
	Char:WaitForChild("HumanoidRootPart").Anchored = false
	script.Parent.TextButton:Destroy()
	script:Destroy()
end)
