Sigma has announced the 24-70mm F2.8 DG DN Art series lens for Sony E and the Panasonic – Leica – Sigma L-mounts. The 24-70mm F2.8 joins the previously-announced 14-24mm F2.8 DG DN Art as the second of Sigma’s DN, or ‘Digital Native’ zooms designed specifically for full-frame mirrorless.

Key features include:

Best-in-class optical performance. The F2.8 Art flagship zoom lens series is developed to achieve superior optical performance. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range. In addition to Super Multi-Layer Coating, Sigma’s proprietary Nano Porous Coating is employed to achieve high-contrast and clear image quality. This lens is designed to be less affected by strong incident light such as flare.

Ensuring compatibility with the latest full-frame mirrorless camera bodies. The Sigma 24–70mm F2.8 DG DN ensures compatibility with various types of the latest full-frame mirrorless camera bodies for Sony E-mount and L-mount, (including the new Sigma fp camera), capable of exerting the best performance under any photographic circumstances.

Flexibility for various uses and photographic environments. Featuring a dust and splash-proof body and zoom lock mechanism for preventing the lens barrel from extending unexpectedly, the 24-70mm F2.8 meets a wide range of needs for a variety of photographic environments. The maximum magnifications are 1:2.9 at the wide-angle end and 1:4.5 at the telephoto end, which provides a wider range of expression for close-up photography. The minimum focusing distance is 18 cm at the wide-angle end.
Additional features:

• Zoom lock switch
• Lens hood with a lock
• Mount with dust- and splash-proof structure
• Compatible with the Lens Aberration Correction
• Available Mount conversion service
• Designed to minimize flare and ghosting
• Evaluation with Sigma’s own MTF measuring system: A1
• 11-blade rounded diaphragm
• High-precision, rugged brass bayonet mount
• “Made in Japan” craftsmanship
• The Sigma 24-70mm F2.8 DG DN Art will be available in L-mount and Sony E-mount in mid-November 2019 through authorized US dealers. Pricing will be announced at a later date.
