Allows a minimum focusing distance of 100cm and a maximum magnification of 1:3.5. This lens is indicated for all types of photography, from the portrait to the panorama to macro applications. Two elements in optical glass SLD (Special Low Dispersion) and three elements ELD (extraordinary Low dispersion) allow excellent correction for all types of aberration.
