The CP +, held until yesterday in Japan, was the occasion for Sigma of a wave of announcements. The company first unveiled the price of its 14-24 mm f / 2.8 DG HSM Art which will see the day mid-March to € 1,640 excluding taxes. She also took the opportunity to present two new objectives that come to join its range of high quality Art.
Sigma 70 mm f / 2.8 DG Macro Art
This is not totally new, but rather a update of its Mac 70mm f / 2.8 EX DG that offers Sigma. Unlike current trends that favor internal tuning to avoid lengthening the lens depending on the distance to the subject, the Japanese company says it has prioritized optical quality above all else. The lens is made from 13 elements divided into 10 groups including two FLD glass elements, two SLD glass elements, one with an anomalous high refractive index dispersion ratio and two aspherical lenses. The focus is ensured by two floating optical groups, driven by a DC motor without cores, with a "by-wire" electrical transmission avoiding direct mechanical contact with the ring. The lens nevertheless allows the manual retouch of the point and Sigma indicates that it has equipped this ring with a wide-angle rotation for a more comfortable handling and above all a high precision. However, the goal has no stabilization system. No availability dates or prices have been announced yet. We only know that a full-size Sony E version is planned, that the lens will be compatible with the on-board optical corrections of the Canon cameras as well as the Sigma teleconverters and the EM-140 DG macro flash. Its minimum focus distance is 25.8 cm for an enlargement ratio of 1: 1. This is the first macro lens in the Art range, since the Macro 105 f / 2.8 EX DG OS HSM has not been updated yet.
Sigma 105mm f / 1.4 DG HSM Art
Introducing the 105mm f / 1.4 DG HSM Art, Sigma also unveils its longest focal length f / 1.4 aperture. The brand brings to nine the number of f / 1.4 opening references in its catalog, six of which cover the 24×36 format. The manufacturing of this lens is impressive since it has 17 lenses divided into 12 groups including three elements FLD glass, two SLD glass and an aspherical lens. Its very wide opening and circular diaphragm with nine slats should offer great bokeh, but it will bear the consequences since the lens weighs 1,645 g and measures 13 cm long and a diameter of nearly 12 cm. It will be necessary to add to it 105 mm filters. Comes with all the necessary accessories, this 105 mm has a removable foot collar to the Arca-Swiss standard, as well as a sunscreen made of CFRP (polymer with carbon fiber reinforcement). lighter and stronger than the usual ABS plastic polymer. It is equipped with several seals and benefits from a water-repellent surface treatment on its front lens. On the other hand, it does not have a stabilization system. As for the 70 mm macro, a full-size Sony E version is planned and the lens will be compatible with on-board optical corrections for Canon cameras. Its price and availability date have not been released.
Soon Sony E versions in the Art range
In addition to the two models unveiled at CP +, Sigma has announced that it will gradually offer the seven fixed focal lengths of its Art range in Sony E mount. It is the 14 mm f / 1.8 DG HSM, 20 mm, 24 mm, 35 mm, 50 mm, 85 mm f / 1.4 DG HSM and the 135 mm f / 1.8 DG HSM. These lenses reflect the optical formulas of the models for SLRs, but benefit from a new mount and therefore new communication algorithms, in particular for a perfect compatibility of the autofocus systems and the stabilization by the sensor of the devices. These new optics will be eligible for the Sigma frame change whose price should however increase soon. The brand has not given a date of availability or price for these objectives.
