Is wide-angle lens bionics?

Wide-angle lens is not bionics.

Bionics refers to the science of imitating organisms to build technical devices, and it is a new frontier science that appeared in the middle of last century. Bionics studies the structure, function and working principle of objects, and transplants these principles into engineering technology to invent instruments, devices and machines with superior performance and create new technologies. People were inspired by bats to invent radar, velcro from Xanthium plants, sonar from dolphins and "fly's eye lens" from flies. The "fly-eye lens" is composed of hundreds or thousands of small lenses arranged neatly. It can be used as a lens to make a "fly-eye camera" and can take thousands of identical photos at a time. Wide-angle lens is not the research result of bionics.

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens. Wide-angle photography is shooting with a wide-angle lens. The field of view of the wide-angle lens exceeds 45 degrees; 45 degrees is the approximate viewing angle of a standard or ordinary lens for a known diaphragm. In any picture, the wide-angle lens is always shorter than the normal focal length.
