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 ...

35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...

Leitz Elmarit R19/2.8 ultra wide angle lens for Leica R cameras Ihagee Exa camera with Carl Zeiss Jena Flektogon 1:4 20 mm super wide angle lens. An ultra wide-angle lens is a lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the ...
The 18-300mm f /3.5–6.3 G lens (not to be confused with the 18-300mm f /3.5–5.6 G lens) is a telephoto superzoom lens manufactured by Nikon for its line of DX DSLR cameras. As with other DX format lenses, the smaller image circle makes it compatible only with APS-C -sized image sensors .
However, it was not until 1963 the Topcon name became famous by introducing the Topcon RE Super, an event that took the entire camera industry by surprise: This camera featured through-the-lens exposure metering, at full lens aperture. The RE Super was fully prepared for professional work, supported by a choice of lenses and accessories to ...
