Sigma has announced two new full-frame lenses for its Contemporary line, the Sigma 24mm F2 DG DN C and the Sigma 90mm F2.8 DG DN C.
The 24mm F2 DG DN C and 90mm F2.8 DG DN C are new additions to Sigma’s I series of compact prime lenses for mirrorless cameras. They both feature an all-metal barrel, an aperture ring and focusing driven by a stepping motor.
Sigma 24mm F2 DG DN C
According to Sigma, the 24mm F2 DG DN C offers the highest level of optical performance even when used at its maximum aperture of f/2.
It’s constructed from 13 elements in 11 groups with two SLD glass elements and one FLD glass element. The SLD and FLD elements correct axial chromatic aberration, which can be a significant issue with bright lenses. It also has two high-precision glass-moulded aspherical elements to reduce the overall number of elements required, thus reducing the size and weight of the lens.
Sigma has also applied its Super Multi-Layer Coating and supplies a petal-type lens hood.
Key features

Sigma 90mm F2.8 DG DN C
Like the Sigma 24mm F2 DG DN C, the 90mm F2.8 DG DN C is a compact prime lens.
Sigma has used its very latest optical technology to create the 90mm F2.8 DG DN C and it’s constructed from 11 elements in 10 groups with five SLD elements and one glass-moulded aspherical element. Sigma’s Super Multi-Layer Coating has also been applied.
