Large-aperture, ultra-wide-angle zoom with expressive imaging capabilities

By utilizing unique optics which have been designed to correct lens aberrations, the SIGMA 10-18mm F2.8 DC DN | Contemporary produces images that are sharp across the entire image. The use of an aspherical lens with large eccentricity and refractive index as the first lens element has enabled a lens construction with a reduced number of elements. Used in conjunction with multiple aspherical lenses and special low-dispersion glass, the lens can produce high resolution images whilst remaining compact and lightweight.
