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. Many lens designs have been ...
Canon 24-240mm F4-6.3, a superzoom lens. This is a list of superzoom lenses, sometimes referred to as all-in-one lenses, that are designed for mirrorless cameras.. There is no precise definition of superzoom, but lenses marketed as such usually have an optical zoom ratio greater than 7×. [1]

The Sigma 50-500mm f / 4-6.3 EX DG HSM is a super-telephoto zoom lens produced by Sigma Corporation. It contains four SLD (Special Low Dispersion) glass elements to provide correction for chromatic aberration.
It is exceedingly difficult to construct a compact lens with such high zoom ratios, which means that the longest zoom lenses may not be the sharpest. For example, the Sony RX100 VII (8×) is sharper than the Panasonic ZS200 (15×), and the Sony HX99 (30×) is sharper than the Canon SX740 (40×).
