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

A Classic, Evolved

The Sigma 24-70mm f/2.8 DG DN II Art Lens, designed for the Leica L-mount, offers a refined version of the original model with a more compact and lightweight build, enhanced performance, and numerous upgraded features. This flagship lens boasts superior rendering capabilities and an advanced optical design, ensuring notable improvements in sharpness, resolution, and portability. With a faster autofocus, tactile aperture ring, and impressively short 6.7-inch minimum focusing distance, this versatile lens is the perfect choice for photographers and videographers.

Sophisticated Optical Design

Sigma has incorporated advanced optical elements to improve image quality across the entire zoom range. The lens features six “F” Low Dispersion (FLD) elements and two Special Low Dispersion (SLD) elements, which work together to significantly reduce chromatic aberrations and color fringing. These elements enhance overall clarity and ensure accurate color reproduction. In addition, five aspherical elements help minimize distortion and contribute to a more compact lens design, allowing for better portability without sacrificing optical performance.

One of the key benefits of these optical improvements is the increased control over sagittal coma flare, which is often problematic in wide-angle lenses. The result is high-resolution imagery with greater consistency across the frame, particularly at the edges. The bright f/2.8 aperture, combined with a rounded 11-blade diaphragm, produces a beautifully smooth bokeh, allowing for aesthetic background blur in portraits and other creative compositions.

Furthermore, advanced Super Multilayer and Nano Porous coatings have been applied to the lens elements, reducing lens flare and ghosting while enhancing contrast and color neutrality. These coatings ensure that the lens performs well even in challenging backlight situations, maintaining clear and vibrant images.

In addition, this lens suppresses focus breathing, a common issue with zoom lenses. This design provides a more natural and seamless transition in focus during video recording.

Focus Faster, Focus Closer

The Sigma 24-70mm f/2.8 DG DN II Art Lens introduces a high-response linear actuator (HLA) motor to drive its autofocus system. This motor improves focusing speeds by more than three times compared to its predecessor, delivering fast and precise autofocus performance. This upgrade is especially useful for dynamic subjects or fast-paced shooting environments.

At the wide-angle end of the zoom range, the lens has an impressive minimum focusing distance of just 6.7 inches, which makes it ideal for close-up shots or working in tight spaces. With a maximum magnification ratio of 1:2.7, this lens can capture fine details and deliver sharp, high-quality close-up imagery with ease.

Built Strong and Svelte

This Sigma 24-70mm f/2.8 DG DN II Art Lens retains the same number of elements as its predecessor, but is lighter and more compact. A lightweight lens that weighs only 1.6 pounds and measures just 4.7 inches long, it’s easy to carry and use for long shooting sessions, so it’s a great choice for photographers.

A clickable aperture ring allows tactile aperture adjustment, while a lock switch secures the setting. The zoom extension mechanism is made from metal components, with rubber seals around the mount protecting it against dust and moisture.

Additionally, the lens has two customizable AF-L buttons, allowing users to adjust various shooting functions easily and conveniently. As well as an autofocus/manual focus switch, a zoom lock switch prevents the barrel from accidentally extending when not in use.

Overall, the Sigma 24-70mm f/2.8 DG DN II Art Lens is an exceptional choice for both photographers and videographers seeking versatility without compromising on quality.
