Sigma 85mm f1.4 DG HSM Art


Camera - - AWARDS -

“Sigma’s new­est Art Se­ries prime lens is aimed at por­trait

pho­tog­ra­phers and any­one who want to utilise the dra­matic, shal­low depth-of-field ef­fects avail­able at 85mm and f1.4. The op­ti­cal de­sign in­cludes two ‘FLD’ (flu­o­rite equiv­a­lent) el­e­ments and one with anoma­lous par­tial-dis­per­sion (AD) char­ac­ter­is­tics with a high-re­frac­tive index to de­liver ex­tremely low lev­els of chro­matic aber­ra­tion. The lens has a nine-blade elec­tron­i­cally-con­trolled di­aphragm, Sigma’s up­graded HSM fo­cus­ing drive (with a 1.3x torque boost to in­crease speed and ac­cu­racy), a durable brass mount and bar­rel tubes made from a spe­cial ma­te­rial called Ther­mally Sta­ble Com­pos­ite (TSC) which pro­vides con­sis­tent per­for­mance in ex­treme tem­per­a­tures and is con­sid­er­able lighter than the other ma­te­ri­als that would yield sim­i­lar ben­e­fits.”
