The Laowa Probe lens is a strange looking "snorkelling lens", but it is one of the most interesting macro lenses on the market and with this endoscope lens you can take unique photos and videos from the insect perspective that would never be possible with other lenses. 27 lens elements in a 20 mm thin telescope-like and waterproof tube make up this special macro lens. At 24 mm, it is a wide-angle macro lens for full-frame cameras with a maximum reproduction scale of 2:1. The wide-angle design and small aperture result in a huge depth of field. An LED ring light is built into the tip for illumination and focusing. Thanks to this design, unique effects can be achieved in the tabletop, macro and close-up range. Not only shots from a low perspective but also shots that seem physically impossible are possible with ease.there are no limits to creativity with this lens.you can use a power bank or a USB power supply unit as a power source for the built-in LED ring light.
