The Austrian Digitalstore already listed the E-mount version of the new Sigma lens. Specs are obviously valid for the L-mount version too!

A classic, further developed.
The SIGMA 24-70mm F2.8 DG ON II I Art is SIGMA’s flagship lens that has evolved significantly from its predecessor, incorporating the most advanced technologies available to SIGMA from design to production. Compared to the previous SIGMA 24-70mm F2.8 DG ON I Art, the SIGMA 24-70mm F2.8 DG ON III Art has improved resolving power throughout the zoom range and also benefits from functional improvements such as the addition of an aperture ring and high-speed AF with a newly developed AF motor, HLA (High-Response Linear Actuator). The lens is also around 7 % smaller and 10 % lighter. This 24-70mm F2.8 Art zoom lens is a versatile and powerful tool to help photographers and filmmakers realize their creative potential.
Versatile and powerful tool
The Sigma Art 24-70mm F2.8 DG DN II is around 7% smaller and 10% lighter than its predecessor. This makes it a versatile and powerful tool that allows photographers and filmmakers to realize their full creative potential.
The optical design of the lens includes 6 FLD glass elements, 2 SLD glass elements and 5 aspherical lens elements to thoroughly suppress various aberrations over the entire zoom range. Sagittal coma flicker in particular has been well controlled to achieve consistently high resolution right to the edge of the image. The effective correction of lateral chromatic aberrations enables high-resolution images without colour fringing.
Integration of 5 aspherical lenses
The use of 5 high-precision aspherical lenses enables high optical performance with minimal correction of aberrations and a compact optical design. High-precision aspherical molding technology at SIGMA’s sole production plant in Aizu enables the manufacture of the thin, highly polished aspherical lenses that are essential to the construction of this lens. This has led to greater freedom in optical design.
Outstanding close-up range
With a close focus distance of 17 cm at the wide-angle end and a maximum magnification of 1:2.7, the lens offers an excellent close focus distance, which is useful when composing close-ups of a subject or when photographing in tight spaces where it is difficult to maintain a good distance from the subject.
Minimizing flare and ghosting
Flare and ghosting, which affect image quality, have been largely eliminated using advanced simulation technology to ensure that the lens delivers rich, high-contrast results in all conditions. In addition, a nanopore coating and a super multi-layer coating have been used to suppress flare and ghosting as much as possible. The high backlight resistance enables clear and sharp images under all lighting conditions.
