Sigma has announced the 24-70mm F2.8 DG DN Art Zoom Lens for Full Frame Mirrorless Cameras. It will be available in Sony E-mount and L-mount.
This is the second newly-designed Art zoom lens from Sigma and follows on from the 14-24mm F2.8 DG DN Art zoom. Sigma claims that the 24-70mm F2.8 DG DN Art Zoom lens features best-in-class optical performance due to a sophisticated optical design that is said to deliver high resolution throughout the entire zoom range.
The 24-70mm F2.8 DG DN Art lens features a reduced lens size and weight while achieving what Sigma says is uniformity and high resolution from the center to the periphery throughout the zoom range.
The F2.8 Art flagship zoom lens series is developed to achieve good optical performance. By employing three aspheric lenses, this zoom lens is claimed to thoroughly subdue aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing,
The lens is also said to achieve 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.
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.
Dust & Splash Proof Body
The lens features a dust and splash-proof body and zoom lock mechanism for preventing the lens barrel from extending unexpectedly.
- Zoom lock switch
- Lens hood with a lock
