Rendering performance worthy of the flagship name

The Sigma 24-70mm F2.8 DG DN II | Art is the successor to the Sigma 24-70mm F2.8 DG DN | Art, which is known for its high optical performance, and has further improved resolution throughout the zoom range. The lens has high sharpness throughout the entire image from its maximum aperture, even on high-resolution cameras. Focusing on enhancing its rendering performance, the brightness of F2.8 produces a large, beautiful bokeh effect, and allows users to experience the power of a flagship lens in all types of visual expression. In addition to its advanced close-up capability and resistance to flare and ghosting, the lens is designed to minimize focus breathing, providing ideal images in any situation

High optical performance across the entire image and zoom range

The optical design of the lens includes 6 FLD glass elements, 2 SLD glass elements, and 5 aspherical lens elements to thoroughly suppress various aberrations throughout the entire zoom range. In particular, sagittal coma flare has been well controlled to achieve consistently high resolution all the way to the periphery of the image. By also effectively correcting lateral chromatic aberration, high resolution, beautifully rendered images can be achieved, free from color fringing can be achieved.

Incorporating 5 aspherical lenses

The use of 5 high-precision aspherical lenses enables both high optical performance with minimal aberration correction and a compact optical design. The Sigma's only manufacturing base, the Aizu factory’s ultra-high-precision aspherical molding technology makes it possible to produce the thin, highly polarized aspherical lenses that are essential for the construction of this lens. This has brought about a higher degree of freedom in optical design.

Excellent close-up capability

The lens has excellent close-up capability with a minimum focusing distance of 17cm / 6.7in. at the wide end and a maximum magnification ratio of 1:2.7. This is useful when composing close-up shots of a subject, or when shooting in tight spaces where it is difficult to get a good distance from the subject. * Be extremely careful that the front lens element does not hit the subject when photographing. Remove the lens hood when photographing at the minimum focusing distance at the wide-angle end.

Designed to minimize flare and ghosting

Flare and ghosting, which reduce image quality, have been largely eliminated using advanced simulation technology, ensuring the lens renders rich, high-contrast results in all conditions. In addition, Nano Porous Coating and Super Multi-Layer Coating have been applied to help suppress flare and ghosting to the utmost degree. High backlight resistance enables clear and sharp images under any lighting conditions

Minimal focus breathing

The lens has been designed to suppress focus breathing. The change in angle-of-view due to focus shift across the entire zoom range is minimized, creating a natural-looking focus pulls when recording video.

Improved portability and expanded feature set

The body of the Sigma 24-70mm F2.8 DG DN II | Art is approximately 7% smaller in size and 10% lighter in weight than the previous model, while improving usability by adding an aperture ring and two AFL buttons. Despite the reduction in size and added features, the lens maintains Sigma’s renowned excellent build quality, with the uncompromisingly precise and robust construction expected of a professional photographic tool.

Highly portable lens body

While the number of lens elements used in its construction is the same as that of the previous model, the overall length has been shortened owing to an advanced optical design. In addition, the more efficient mechanical design has resulted in a highly portable lens body with a maximum diameter of φ87.8mm x 120.2mm / φ3.5in. x 4.7in., and weight of 745g / 26.3oz. * * These figures are for L-Mount.

Excellent build quality

Simultaneously focusing on reducing the size and weight of the lens body, the use of metal parts for the zoom extension unit and other parts, as well as the robust internal structure ensure rigidity during use, such as when operating the ring, pressing buttons, and carrying the lens. The design emphasizes the lens’ longevity and reliability as a tool, which cannot be achieved by solely pursuing a compact and lightweight body.

Equipped with an aperture ring

The lens is equipped with an aperture ring as well as an aperture ring click switch and an aperture ring lock switch, allowing for aperture operation suitable for various shooing situations.

MTF CHART

The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens' performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1). The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is. The MTF chart depicts the result at the wide-open aperture. For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.) *The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Inner focus system

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality. Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model. On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON' (AUTO).

HLA (High-response Linear Actuator)

HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.

Super Multi-Layer Coating

Sigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.

Nano Porous Coating

NPC (Nano Porous Coating) incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

Water and oil repellent coating

Water and oil repellent coating Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

Aperture ring

Aperture ring, designed to help users work intuitively.

Aperture ring click switch

Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.

Aperture ring lock switch

A ring lock system to prevent from unintended movement of the aperture ring during shooting.
