“Con­tin­u­ing the Sigma Art line’s tra­di­tion of excellence in lens

de­sign, the 12-24mm zoom de­liv­ers im­pres­sive ul­tra-wide ca­pa­bil­i­ties on full-35mm D-SLR bod­ies com­bined with a con­stant aper­ture of f4.0. The 16-el­e­ment op­ti­cal con­struc­tion in­cludes ‘F Low Dis­per­sion’ (FLD) types which have the ul­tra-low dis­per­sion char­ac­ter­is­tics of flu­o­rite glass to ef­fec­tively cor­rect for chro­matic aber­ra­tions. It also in­cludes the world’s largest-di­am­e­ter moulded glass as­pher­i­cal el­e­ment to help min­imise dis­tor­tion and vi­gnetting. An up­dated ver­sion of Sigma’s HSM aut­o­fo­cus­ing drive is 1.3x quicker. The ex­ter­nal bar­rel is sealed to pro­vide weather pro­tec­tion while a spe­cial water- and oil-re­pel­lent coat­ing is used on the ex­posed sur­faces of the front and rear el­e­ments. Ad­di­tion­ally, the lens mount is ma­chined from brass to give ex­tra dura­bil­ity.”
