Sigma has announced its first lenses for the Fujifilm X-mount, a trio of primes covering 16mm, 30mm and 56mm focal lengths, all with f/1.4 maximum apertures.

The new lenses, unveiled just before the CP+ show opened, are scheduled for international release on 8 April, 2022 and are almost identical to previous lenses, which were produced with Canon EF-M, Leica L, M4/3 and Sony E mounts. As well as sharing a fast, f/1.4 maximum aperture, all three lenses have the following features in common:
- Brass bayonet mounts for superior durability and strength;
- Rubber sealing aroudn the mount to prevent the ingress of dust and moisture;
- Rounded, nine-blade iris diaphragms that create circular apertures for attractive bokeh;
- Inclusion of special low dispersion (SLD) glass to minimise chromatic aberration.
The optical design of the 16mm f/1.4 DC DN | Contemporary lens (shown above) contains 16 elements in 13 groups and includes two FLD elements, two super low-dispersion (SLD) elements and two aspherical elements. This lens covers an angles of vide of 83.2 degrees and has a minimum focus of 25 cm with 1:9.9 magnification. It measures 92.6 mm in length and 72.2 mm in diameter, weighs 405 grams and accepts 67mm filters. It is supplied with the LH716-01 lens hood.
The optical design of the Sigma 30mm f/1.4 DC DN | Contemporary lens (shown above) contains nine elements in seven groups, with two aspherical elements. This compact lens covers a 50.7 degree angle of view and is 73.6 mm long, with a 64.8 mm diameter and weight of only275 grams. It accepts 52 mm filters and is supplied with the LH586-01 lens hood.
The 56mm f/1.4 DC DN | Contemporary lens is the smallest medium-telephoto in its class, weighing only 280 grams and measuring 59.8mm in length and 66.5mm in diameter. Its optical design, shown above, consists of 10 elements in six groups and includes one aspherical and one special low dispersion (SLD) glass to minimise chromatic aberration. This lens accepts 55 mm filters and is supplied with the LH582-01 lens hood. Click here for more information.
Sigma has also announced plans to introduce an X-mount version of the 18-50mm f/2.8 DC DN | Contemporary lens, which is currently available in Sony E-mount and L-Mount versions. However, it is not expected until the end of the year.
In another announcement at CP+, Sigma has revealed it is in the second of three stages in developing its new full-frame Foveon sensor. The company is currently in Stage 2, where it is prototyping the design on a much smaller sensor than the full-frame sensor it hopes to make available in a camera. Once this stage has been completed, it can decide whether to go ahead or go back and re-prototype Stage 2. Despite the potential advantages of the three-layer structure with separate layers for red, green and blue pixels, development of the full-frame sensor hasn’t gone smoothly since 2018, although it is closer than it was in 2020, when the company scrapped previous efforts and had to start again from scratch.
