A superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination wavelength and the numerical aperture (NA) of the objective lens.

A photographic lens or objective is an integrated system comprising one or more simple optical lens elements, which produces an image of a distant object. The main article for this category is Photographic lens .
A number of versions of the Sonnar lens soon followed, with focal lengths from 50 to 300 mm developed until 1940. Around 1934, Bertele, using the design of the f /1.5 Sonnar lens as a base, created the first wide-angle lens, the Biogon, with a 60° viewing angle; the original Biogon design was reused for the Wild Aviotar.
