Sigma has announced the release of three (3) high-end ‘Art’ lenses: two primes and one zoom. All three lenses are designed for full-frame DSLR’s from Canon, Nikon and Sigma.
Sigma 14mm f1.8 DG
The first lens is the ultra-wide 14mm F1.8 DG HSM, which Sigma claims is the ‘world’s first and only F1.8 ultra-wide-angle lens.’ The lens has 16 elements, three of which are FLD (low dispersion) and four are SLD (super-low-dispersion). It also has a large (80mm) aspherical front element to reduce distortion and ‘deliver outstanding image quality from the center to the edges.’ The 14mm F1.8 has 9 rounded aperture blades, a minimum focus distance of 27cm/11in and a ring-type ultrasonic (HSM) focus motor.
Sigma 24-70mm f2.8 DG Art
Next Sigma has announced a 24-70mm F2.8 DG OS HSM Art. This lens features three SLD and four aspherical, nine rounded aperture blades and optical image stabilization. The lens is weather-sealed and made of a combination of metal and ‘thermally stable composite’ material. The minimum focus distance of the 24-70 is an impressive 37cm/14.5in and it uses 82mm filters.
Sigma 135mm f1.8 DG
And finally there is the Sigma 135mm F1.8 DG HSM telephoto prime. Sigma says that this lens I quote ‘offers the […] resolution required for 50MP or higher ultra-high-megapixel DSLRs.’
It has a hypersonic (ring-type ultrasonic) focus motor that delivers fast (and ‘exceptionally stable’) focus speeds, while an acceleration sensor ‘detects the orientation of the lens’ so the AF system can respond to ‘varying loads on the focusing group due to gravity.’ The lens has 9 rounded aperture blades, dust and splashproof construction, and a weight of 1130g/40.2oz. This last lens in particular is likely to appeal to concert shooters where the “fast” f1.8 aperture will prove very useful.
