Sigma has updated its range of lenses for full-frame mirrorless cameras and announced three existing prime lenses will come with new Canon EF-M mounts.

The 14-24mm f/2.8 DG DN | Art lens has been developed primarily  for photographing starry night skies with full-frame mirrorless cameras. This lens is quite different from the similarly-specified DSLR lens and it utilises the short flange focal length of L-Mount and Sony E-mount cameras to combine a compact body with high-resolution image quality. Its optical design consists of 18 elements in 13 groups and includes one FLD glass and five SLD glass elements as well as three aspherical elements. The front element is a large-diameter aspherical element. A new Nano Porous Coating has been applied to resist ghosting and flare and the front element carries an oil- and water-repellant coating.

The new Sigma 35mm f/1.2 DG DN | Art lens is the company’s first with a f/1.2 maximum aperture. Its optical design contains 17 elements in 12 groups and includes three SLD glass elements and three aspherical lenses, one of them a double-sided aspherical lens. It is extensively weather-sealed, has a fluorine coating on the front element to repel dust and grease is said to offer ‘the ultimate image quality’.

A new addition to Sigma’s Contemporary lens line-up, the 45mm f/2.8 DG DN | Contemporary lens is compact and light, with an overall weight of only 215 grams. Its optical design features eight elements in seven groups and it appears to have no exotic elements. According to Sigma, spherical aberration has been controlled but some vignetting has been included to improve the bokeh characteristics of the lens (vignetting draws viewers’ eyes to the centre of the picture). Autofocusing is driven by a stepping motor, making the lens suitable for shooting video. Seven diaphragm  blades close to a circular aperture.

Very little information has been provided on Sigma’s Global Vision website and no information has been provided so far on local release dates and pricing. (We’ll update this announcement when it becomes available.)

Sigma is also updating three existing lenses, which were previously only available for Micro Four Thirds and APS-C Sony E-mount cameras, for the Canon EF-M mount. These lenses are the 16mm f/1.4, 30mm f/1.4 and 56mm f/1.4. Again, no details are available so far and these lenses have yet to be listed on the local website.
