Sigma 24-70mm f/2.8 Art DG DN Lens for Sony E Mount

The Sigma 24-70mm f/2.8 DG DN Art lens is recognized as a reliable and essential tool for Sony E-mount full-frame mirrorless systems. This versatile zoom lens spans from wide-angle to portrait lengths and features a constant maximum aperture of f/2.8. Its bright design is particularly advantageous for shooting in available light, allowing for greater control over depth of field. The lens's optical construction includes several low dispersion and aspherical elements, which significantly minimize various aberrations, resulting in exceptional sharpness, clarity, and color fidelity. To further enhance performance, both Super Multi-Layer and Nano Porous Coatings have been applied, effectively reducing lens flare and ghosting, thus improving contrast and color rendering in challenging lighting situations. Additionally, the lens is equipped with a stepping autofocus motor, providing rapid, accurate, and remarkably quiet focusing capabilities. With a maximum magnification ratio of 1:2.9 at the wide end, it is well-suited for close-up photography, while its 11-blade diaphragm contributes to aesthetically pleasing bokeh. Furthermore, the weather-sealed construction ensures reliability in adverse environmental conditions.

Full-Frame and APS-C Compatible Autofocus Lens

The standard zoom lens is specifically engineered for full-frame Sony E-mount mirrorless cameras; however, it is also compatible with APS-C-format models, offering a focal length equivalent of 36-105mm. The lens features an integrated stepping motor that enables rapid and silent autofocus, enhanced by an optimized autofocus algorithm to ensure a smoother focusing experience.

Sophisticated Optical Design

The inclusion of six F Low Dispersion (FLD) elements and two Special Low Dispersion (SLD) elements significantly mitigates chromatic aberrations and color fringing across the entire zoom range, enhancing both clarity and color fidelity. Additionally, three aspherical elements are utilized to manage spherical aberrations and distortion, resulting in heightened sharpness and precise image rendering. Furthermore, Super Multi-Layer and Nano Porous Coatings have been implemented on the lens elements to reduce lens flare and ghosting, thereby facilitating the creation of imagery that is rich in contrast and color-neutral, even under backlit conditions.

Close Focus with Pleasing Bokeh

At the wide-angle position of the zoom range, a minimum focusing distance of 7.1 inches can be achieved, allowing for a maximum magnification of 1:2.9, which is ideal for capturing close-up subjects. Conversely, at the telephoto end, the minimum focusing distance extends to 1.25 feet, with a maximum magnification of 1:4.5. Additionally, the rounded 11-blade diaphragm enhances the aesthetic quality of the bokeh.

Lens Features

The integrated AF-L button can be customized to modify a range of shooting parameters, while the lens is equipped with a specific AF/MF switch and a zoom lock switch to prevent unintentional extension of the barrel. The built-in stepping motor facilitates rapid and silent autofocus, enhanced by a refined AF algorithm that ensures a more fluid focusing experience. Additionally, the chrome-plated brass bayonet lens mount enhances mounting precision and stability. The design of the mount includes rubber seals, providing dust and splash resistance, thus enabling image capture in challenging conditions.
