F-stops and aperture are KIND OF talking about the same thing! The aperture is measured in f-stops so.. the more stops, the smaller the opening. So the aperture is the diameter of the opening but the f-stop is the aperture divided by the focal length, that's the reason for the numbers. IF THAT MAKES SENSE.
