Sigma has recently focused on the Contemporary series of lenses aimed at the mass market. The last Art lens that pursued ultimate optical performance was the 35mm F1.4 DG DN|Art full-frame mirrorless single lens released more than a year ago. However, recent news indicates that Sigma will soon release two wide-angle large-aperture lenses, 20mm F1.4 DG DN|Art and 24mm F1.4 DG DN|Art, so that users who use full-frame E-mount and L-mount can enjoy the benefits. benefit.
Although the spy photos of the two lenses have not been exposed yet, the basic specifications have been leaked. The 20mm F1.4 DG DN|Art uses an optical structure of 17 elements in 15 groups, including 2 SLD ultra-low dispersion lenses and 3 aspherical lenses. , providing 11 circular aperture blades, the minimum focusing distance is 0.23 meters, and the maximum magnification is 1:6.1. However, because it uses an 82mm diameter filter, it is not light. The E-mount version weighs 630g, and the L-mount version weighs 635g. The length of the lens body is 113.2mm (E mount), while the L mount is 111.2mm longer.
As for the 24mm F1.4 DG DN|Art, it uses a combination of 17 lenses in 14 groups, including 2 FLD fluorochrome extra-low dispersion lenses, 1 SLD ultra-low dispersion lens and 4 aspherical lenses. It also provides 11 circular apertures. blade. The minimum focusing distance of this lens is 0.25 meters, and the maximum magnification is 1:7.1. The 24mm F1.4 DG DN|Art is smaller in appearance than the 20mm F1.4 DG DN|Art, uses a 72mm filter, and is an E-mount version. The length and weight of the lens body are 97.5mm and 510g respectively, while the L-mount version is 95.5mm and 520g.
