This is probably a combination of TweenService and the players Camera.FieldOfView. An implementation could look like this:

local TweenService = game:GetService("TweenService")

-- Default FOV on Roblox places is 70
local camera = workspace.CurrentCamera
local DEFAULT_FOV = camera.FieldOfView

-- Tweens
local tweenInfo = TweenInfo.new(0.2)
local tweenIn = TweenService:Create(camera, tweenInfo, {
    FieldOfView = 60
})
local tweenOut = TweenService:Create(camera, tweenInfo, {
    FieldOfView = DEFAULT_FOV
})

And then, you can use the two tweens when the player open or closes a UI:

-- When you open a UI:
tweenIn:Play()

-- When you close a UI:
tweenOut:Play()
