The Laowa 24mm f/14 2x Macro Probe is not a conventional lens in any respect. It is a 40-centimeter tube with a 14mm front element, designed to be inserted into spaces that a normal lens cannot access — inside a glass of liquid, beneath a flower at ground level, into the interior of a hollow object. It achieves 2:1 magnification — twice life size — while maintaining a 24mm field of view, producing images that could not be made any other way.
