Camera - - WHAT’S NEW -

AT A ROUGH count, Sony is launch­ing one new FE mount lens per month at the mo­ment which is an­other in­di­ca­tion of just how se­ri­ous it is about get­ting to the top of the ILC mar­ket.

Join­ing the 100-400mm tele­zoom an­nounced along with the A9, are two wide-an­gle zooms – the FE 16-35mm f2.8 GM and the FE 12-24mm f4.0 G. Like the 100-400mm, the 16-35mm is a high-per­for­mance ‘G Mas­ter’ model which are de­signed to com­pete with the likes of Canon’s L Se­ries mod­els. Both the new wide-an­gle zooms fea­ture fully weather-proofed ex­ter­nal con­struc­tions and Sony’s ‘Di­rect Drive Su­per Sonic Wave’ (DDSSM) aut­o­fo­cus­ing mo­tors which have been spe­cially de­signed to meet the de­mands of in­ter­nal fo­cus­ing us­ing large-di­am­e­ter el­e­ments.

The 16-35mm’s 16-el­e­ments op­ti­cal con­struc­tion in­cludes two ‘XA’ types – ex­treme as­pher­i­cal – one of which Sony claims is “the largest XA el­e­ment ever pro­duced”. The XA el­e­ments plus three ad­di­tional as­pher­i­cal types cor­rect for dis­tor­tion and also op­ti­mise cen­tre-to-cor­ner sharp­ness. Two ex­tra-low dis­per­sion el­e­ments cor­rect for chro­matic aber­ra­tions. This lens em­ploys two DDSSM piezo­elec­tric drives in a float­ing fo­cus­ing sys­tem to de­liver faster aut­o­fo­cus­ing. The 16-35mm has an 11-bladed di­aphragm to give smoother out-of-fo­cus ef­fects and sup­ple­ments its weather-proofed bar­rel with a flu­o­rine coat­ing on the ex­posed sur­face of the front el­e­ment to re­pel mois­ture and grease. It also has Sony’s ‘Nano AR’ multi-coat­ings to re­duce ghost­ing and flare.

The 12-24mm has a 17-el­e­ments op­ti­cal con­struc­tion which in­cludes four as­pher­i­cal types to cor­rect for dis­tor­tion and a com­bi­na­tion of three ex­tra-low (ED) dis­per­sion types and one ‘Su­per ED’ type to counter chro­matic aber­ra­tions. It em­ploys ‘Nano AR’ multi-coat­ings to min­imise flare and ghost­ing. Other fea­tures in­clude a seven-blade di­aphragm, cus­tomis­able fo­cus hold but­ton and alu­minium al­loy bar­rel tubes. The min­i­mum fo­cus­ing dis­tance is 28 cm.

With the ar­rival of th­ese two new zooms (prices yet to be an­nounced), Sony’s FE mount sys­tem now spans 12mm to 800mm (al­beit achieved via a tele­con­verter) which is quite an achieve­ment for a sys­tem that’s not yet four years old. For more in­for­ma­tion visit
