You can easily determine the coverage with a piece of cardboard. Turn off all lights in the room, darken the windows, point the lens out the window at a distant object and hold the white cardboard up behind the lens. Move the board towards and away from the lens till the object is sharp on the board. That’s what it covers. Stop down to see how large the circle gets.
