Help with basic camera manipulation?

I have a concept for a menu in mind and ran into some trouble. I have two blocks I'd like the camera to spin around, and when I click buttons, I wanted to make the camera smoothly go between each block and spin around the blocks.

Here is a video of what it does: https://streamable.com/9c1ipv I've tried everything and I don't know why it cuts like that. Here's my code for the camera spin:

plr = game.Players.LocalPlayer;
mouse = plr:GetMouse();
frame = plr.PlayerGui:WaitForChild("ScreenGui").Frame;
renderstepped = game:GetService('RunService').RenderStepped;
camera = workspace.CurrentCamera;
TweenService  = game:GetService("TweenService");
camera.CameraType = Enum.CameraType.Scriptable;
camera.CameraSubject = workspace:WaitForChild("Camera Focus");
mouseButton = nil;
--CAMERA
rotationAngle = Instance.new("NumberValue")
tweenComplete = false

cameraOffset = Vector3.new(0, 5, 5)
rotationTime = 15  -- Time in seconds
rotationDegrees = 360
rotationRepeatCount = -1 
lookAtTarget = true  
target = workspace:WaitForChild("Camera Focus");
function spin()
	camera.Focus = target.CFrame
	rotatedCFrame = CFrame.Angles(0, math.rad(rotationAngle.Value), 0)
	rotatedCFrame = CFrame.new(target.Position) * rotatedCFrame
	camera.CFrame = rotatedCFrame:ToWorldSpace(CFrame.new(cameraOffset))
	if lookAtTarget == true then
		camera.CFrame = CFrame.new(camera.CFrame.Position, target.Position)
	end
end

-- Set up and start rotation tween
tweenInfo = TweenInfo.new(rotationTime, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut, rotationRepeatCount)
tween = TweenService:Create(rotationAngle, tweenInfo, {Value=rotationDegrees})
tween.Completed:Connect(function()
	tweenComplete = true
end)
tween:Play()

-- Update camera position while tween runs
renderstepped:Connect(function()
	if tweenComplete == false then
		spin()
	end
end)

Here's the buttons:

--camera manipulation and gui tween test
button = frame.Tween.TextButton;
button2 = frame.TweenB.TextButton;
clicked = false;
function buttonHandeler()
	if clicked == false
	then
		clicked = true;
		print(clicked)
		for i,v in pairs(frame:GetChildren())
		do
			local function moveBack()
				v:TweenPosition(UDim2.new(-.15,0,v.Position.Y.Scale,0),Enum.EasingDirection.Out,Enum.EasingStyle.Bounce,.8,false);
				wait(1)
				v:TweenPosition(UDim2.new(0,0,v.Position.Y.Scale,0),Enum.EasingDirection.Out,Enum.EasingStyle.Bounce,.8,false);
			end
			wait();
			spawn(moveBack);
		end
		if mouseButton == button
		then
			--target = workspace:WaitForChild("Camera Focus B");
			--lookAtTarget = false;
			tweenComplete = true;
			tween:Pause();
			--camera.CFrame = rotatedCFrame:ToWorldSpace(CFrame.new(cameraOffset))
			target = workspace["Camera Focus B"];
			local localtween = TweenService:Create(camera,
				TweenInfo.new(.7,Enum.EasingStyle.Quad,Enum.EasingDirection.InOut),
				{CFrame = CFrame.new(camera.CFrame.Position, target.Position)});
			localtween:Play();
			wait(.7);
			tween:Play();
			tweenComplete = false;
			--lookAtTarget = true;
		else
			--target = workspace:WaitForChild("Camera Focus B");
			--lookAtTarget = false;
			tweenComplete = true;
			tween:Pause();
			--camera.CFrame = rotatedCFrame:ToWorldSpace(CFrame.new(cameraOffset))
			target = workspace["Camera Focus"];
			local localtween = TweenService:Create(camera,
				TweenInfo.new(.7,Enum.EasingStyle.Quad,Enum.EasingDirection.InOut),
				{CFrame = CFrame.new(camera.CFrame.Position, target.Position)});
			localtween:Play();
			wait(.7);
			tween:Play();
			tweenComplete = false;
			--lookAtTarget = true;
		end
	end
	clicked = false;
end
button.MouseButton1Click:connect(buttonHandeler);
button2.MouseButton1Click:connect(buttonHandeler);

Kinda took a break for a while so my mind is a little rusty.
