Sigma 24-70mm f/2.8 DG DN II Art Overview

A Classic, Reimagined for Modern Performance

Sigma 24-70mm f/2.8 DG DN II Art Lens offers enhanced rendering performance in a more compact, lighter form factor.A versatile and high-quality lens with advanced optical design that improves sharpness, resolution, and portability. The new lens features faster autofocus, a clickable aperture ring, and a 6.7-inch minimum focusing distance.

Advanced Optical Engineering for Superior Image Quality

There are six “F” Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and five aspherical elements in the lens. As a result, images are crystal clear and color fidelity is excellent across the entire zoom range. Additionally, these elements help prevent sagittal coma flare, making it ideal for capturing detailed landscapes, architecture, or intricate portraits.

Due to their thin, highly polarized construction, the five aspherical elements contribute to the lens’ sleek and compact design. An 11-blade rounded diaphragm produces a pleasingly smooth bokeh effect, enhancing the visual appeal of out-of-focus backgrounds. Sigma’s lens elements feature super multilayer and nano porous coatings to reduce flare and ghosting. In challenging backlit conditions, this ensures contrast-rich and color-neutral imagery.

Furthermore, this lens is designed to minimize focus breathing—a feature that is particularly valuable for videographers. By suppressing changes in the angle of view during focus adjustments, it offers smooth, natural-looking focus pulls when recording video content, making it an excellent choice for hybrid shooters.

Accelerated Autofocus and Improved Close-up Performance

One of the standout features of this new iteration is its enhanced autofocus capabilities. The integration of a high-response linear actuator (HLA) driven by a linear motor offers focusing speeds that are more than three times faster than the previous model. This improvement translates to quicker, more reliable autofocus performance, ideal for both still photography and video work.

Additionally, the lens excels in close-up photography. At the wide end of the zoom range, it offers an impressive minimum focusing distance of just 6.7 inches, allowing for a maximum magnification of 1:2.7. This feature is perfect for shooting detailed close-ups or working in confined spaces where every inch counts.

Strong, Lightweight Build with Enhanced Handling Features

Sigma has managed to retain the same number of optical elements while making the lens more compact and portable. The overall length has been shortened to 4.7 inches, and the weight has been reduced to a mere 1.6 pounds, making it easier to carry and handle for extended shooting sessions.

The lens design also considers usability. The aperture ring has both click and lock switches, providing tactile feedback during shooting. A durable metal zoom extension mechanism is integrated into the camera body, while rubber gaskets seal the mount to prevent dust and moisture from entering.

In addition, two customizable AF-L buttons allow greater control and flexibility of camera settings. Furthermore, the lens features a dedicated AF/MF switch and a zoom lock switch to prevent unwanted barrel extension.

The Sigma 24-70mm f/2.8 DG DN II Art Lens is a blend of classic design and modern enhancements, catering to both professional photographers and enthusiasts. This lens offers you stunning results in a variety of situations, whether you’re shooting stills or video.
