Sigma 24-70mm f/2.8 DG DN II Art Lens (Sony E)
The Reengineered Flagship Standard Zoom for Mirrorless Systems
The Sigma 24-70mm f/2.8 DG DN II Art represents a definitive evolution of Sigma’s flagship standard zoom, meticulously redesigned to deliver enhanced optical rendering in a significantly shorter, lighter, and more portable lens chassis. Formulated exclusively for full-frame Sony E-mount mirrorless cameras, this high-performance Art-series lens pairs a bright, constant f/2.8 maximum aperture with a sophisticated optical design that achieves exceptional edge-to-edge resolution capable of matching modern high-megapixel sensors.

Beyond its physical downsizing, the Mark II introduction boasts blistering autofocus speeds driven by a cutting-edge linear actuator motor, a newly integrated physical aperture ring, and a highly versatile 6.7-inch minimum focusing distance. Optimized seamlessly for professional wedding shooters, landscape artists, commercial photographers, and high-end video creators, this svelte workhorse redefines standard zoom excellence without compromising performance.

Sophisticated Optical Matrix & Cinematic Control
Flagship-Class Optical Design: Features a premium arrangement of 20 elements configured in 15 groups, incorporating six “F” Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and five precision aspherical components. This advanced layout drastically minimizes chromatic aberrations, color fringing, and sagittal coma flare, maintaining outstanding contrast and clarity across the entire frame.

Ultra-Compact Aspherical Integration: The five highly polarized, ultra-thin aspherical elements allow the lens to maintain a highly dense optical formula while directly contributing to a significantly downsized, portable exterior build.

Constant f/2.8 Aperture & 11-Blade Bokeh: The bright, continuous f/2.8 maximum aperture offers exceptional ambient light-gathering power and superb depth-of-field control. Paired with a rounded 11-blade diaphragm, it produces large, beautifully smooth, and organic background blur (bokeh).

Advanced Multi-Layer Coating Shield: Treated with Sigma’s signature Super Multi-Layer and Nano Porous Coatings to actively suppress surface reflections, ghosting, and internal lens flare, securing rich micro-contrast and color-neutral performance in backlit environments.

Suppressed Focus Breathing: Specifically engineered to limit optical focus breathing as the angle of view changes. This ensures smooth, natural-looking focus pulls when recording cinematic video sequences.

Linear Motor Autofocus & Close-Up Capabilities
High-Response Linear Actuator (HLA): Driven by Sigma’s next-generation HLA linear motor focus system, delivering autofocus locking speeds more than three times faster than its predecessor. This near-silent tracking drive easily keeps pace with high-speed burst shooting and rapid video tracking.

Impressive 6.7-Inch Minimum Focus Distance: At the 24mm wide-angle position, the close-focusing performance improves to a scant 6.7 inches (17 cm) with a maximum magnification ratio of 1:2.7, making it a highly capable tool for tight close-up detail shots or working comfortably within cramped interiors.

Rugged, Ergonomic & Streamlined Build
Svelte, Weight-Reduced Footprint: While retaining a high-density optical layout, the overall physical barrel length has been trimmed down to just 4.8 inches, and the total weight has been cut down to an agile 1.6 pounds—significantly reducing user fatigue during all-day handheld assignments.

Tactile Aperture Control Ring: Features a physical manual aperture ring with two dedicated barrel switches: a De-click switch to allow for smooth, silent iris transitions during video capture, and an Aperture lock switch to prevent accidental setting drift.

Pro-Tier Customization & Weather Sealing: Outfitted with two customizable AF-L (Aperture-Lock/Autofocus-Lock) buttons that can be programmed via Sony camera menus, alongside a dedicated AF/MF toggle switch and a physical zoom lock switch to eliminate barrel creep.

Robust Weather-Resistant Construction: The rigid internal core incorporates structural metal components along the zoom extension, backed by comprehensive dust- and moisture-resistant rubber gaskets along the brass bayonet mount for reliable operation in inclement weather.
