MORE LENS ART FROM SIGMA

Camera - - WHAT’S NEW -

SIGMA HAD A

very busy Pho­tok­ina which in­cluded an­nounc­ing its com­mit­ments to the ‘L Mount Al­liance’, a to­tal of four new D-SLR lenses in its ‘Global Vi­sion’ cat­e­gories (Art, Sports and Con­tem­po­rary), and a new model for the Sony E and Mi­cro Four Thirds mir­ror­less cam­era sys­tems.

Sigma is plan­ning to launch no fewer than 11 L mount lenses (most likely to in­clude all the Art se­ries mod­els re­cently re­leased in Sony’s FE fit­ting), start­ing from the mid­dle of 2019. There will be a new SD Qu­at­tro cam­era body which will have a full-35mm for­mat sen­sor (with the Foveon mul­ti­layer de­sign) and use the L mount too. Sigma says it will dis­con­tinue its own SA mount on cam­eras, but will of­fer an SA-to-L adapter for the ex­ist­ing lenses. It will still make lenses in the SA mount how­ever. It is also plan­ning an EF-to-L adapter which will en­able Canon’s D-SLR lenses – and its own EF mount mod­els – to be used on the ex­ist­ing Le­ica SL body and Pana­sonic’s Lu­mix S1 and S1R L mount mod­els when they ar­rive around mid-2019. The L mount will also be in­cluded in Sigma’s mount con­ver­sion ser­vice which al­ready al­lows you to con­vert your lenses if you change sys­tems.

The new Sigma D-SLR lenses are a 70-200mm f2.8 DG OS HSM Sports (in Canon EF, Nikon F and Sigma SA mounts), a 60-600mm f4.5-6.3 DG OS HSM Sports su­pertele­photo zoom (in the same three mounts), a 28mm f1.4 DG HSM Art (in Canon EF, Nikon F and Sony FE mounts), and a 40mm f1.4 DG HSM Art (for Canon, Nikon, Sigma and Sony). Also new is the 56mm f1.4 DC DN Con­tem­po­rary fast prime for Sony E and MFT mir­ror­less cam­eras.

The new 60-600mm is the world’s first 10x op­ti­cal tele­zoom lens with a tele­photo end of 600mm. The op­ti­cal con­struc­tion com­prises a to­tal of 25 el­e­ments in 19 groups which in­cludes three FLD types (“F” Low Dis­per­sion) and one SLD type (Su­per Low Dis­tor­tion). These spe­cial el­e­ments are de­signed to min­imise chro­matic aber­ra­tions. It in­cor­po­rates an op­ti­cal image sta­biliser which Sigma says gives up to four stops of cor­rec­tion for cam­era shake. The min­i­mum fo­cus­ing dis­tance ranges from 60 to 260 cen­time­tres, giv­ing a max­i­mum re­pro­duc­tion ra­tio of 1:3.3 so this lens also has rea­son­able close-up fo­cus­ing ca­pa­bil­i­ties. On the out­side the bar­rel is weather sealed and the ex­ter­nal con­struc­tion uses a va­ri­ety of ma­te­ri­als – in­clud­ing mag­ne­sium al­loy and dif­fer­ent com­pos­ites – to help min­imise weight with­out com­pro­mis­ing struc­tural in­tegrity. The lens’s hood is also made from CFRP (car­bon­fi­bre-re­in­forced plas­tic) to fur­ther save weight. A flu­o­rine coat­ing is ap­plied to the ex­posed sur­face of the front el­e­ment to help bet­ter re­pel mois­ture and grease. The tri­pod mount­ing col­lar has an Arca-Swiss fit­ting, and other fea­tures in­clude a fo­cus lim­iter, a full-time man­ual fo­cus over­ride, a zoom lock and nine-blade di­aphragm for smoother out-of-fo­cus ef­fects.
