This second newly-designed Art zoom lens from Sigma is a large-aperture standard zoom for full-frame mirrorless camera systems and is available in Sony E-mount and L-mount. The Sigma 24-70mm F2.8 offers best-in-class performance due to a sophisticated optical design that delivers high resolution throughout the entire zoom range. This new Art zoom lens from Sigma follows the debut of the lauded 14-24mm F2.8 DG DN Art zoom for mirrorless cameras.
The Sigma 24-70mm F2.8 DG DN Art lens exerts superiority in mirrorless camera-dedicated designs, resulting in a reduced lens size and weight while achieving uniformity and high resolution from the center to the periphery throughout the zoom range. Compatibility with the latest mirrorless camera bodies and functions assists in various photographic environments and meets the high demands of both professional and advanced amateur photographers.
Best-in-class optical performance
The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance.
As extra-low dispersion glass materials, six sheets of « F » low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. 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, Nano Porous Coating is employed. This lens is designed so as to be less affected by strong incident light such as flare.
The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.
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 tailored for L-Mount and Sony E-Mount so as to be capable of exerting the best performance under any photographic circumstances, assuming that professional or advanced amateur photographers use it.
To the AFL button, for example, various functions can be assigned from a camera body, which enhance the operability while photographing. Employing a stepping motor and the latest algorithm successfully establishes a good balance between acceleration and quietness of the AF drive. This enables stress-free focusing.
Furthermore, this lens is compatible with the Eye-Detection AF used more frequently in mirrorless cameras, which is capable of high-precision focusing at the time of portrait photography.
Adaptable to various uses and photographic environments
The minimum focusing distance is 18 cm at the wide-angle end. This allows you to come closer to a subject than the end of a hood to take photographs. 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 by close-up photography.
Furthermore, the lens adapts to various uses and usage environments through employment of the dust- and splash-proof structure and the zoom lock mechanism for preventing the lens barrel from extending unexpectedly, and meet a wide range of needs for photography. An AF/MF switch used for the many conventional SIGMA’s lenses is also embedded in the lens barrel. Essential and basic functions are also equipped.
