rendering performance, functionality, and portability.
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.
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.
Dual HLA incorporating a new system
A new system was developed that significantly reduces the volume while maintaining the same thrust of the HLA, which is characterized by its high driving accuracy and quietness, and is featured in each of the two focus groups. This technological innovation has realized both high-speed autofocus and a compact lens body.

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.

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 87.8mm / 3.5in., length of 120.2mm / 4.7in., and weight of 745g / 26.3oz.* * These figures are for L-Mount.
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.
Equipped with two AFL buttons
The lens is equipped with two AFL buttons*, to which a range of functions can be assigned via the menu on selected cameras, one more than the previous model. In addition to the side, the additional button has been positioned on the top to facilitate button operation when the camera is held in vertical orientation.
* Functions can be assigned on supported cameras only. Available functions may vary depending on the camera used.
A wealth of functions including high-speed autofocus
In addition to high-speed AF with HLA (High-response Linear Actuator), the SIGMA 24-70mm F2.8 DG DN II | Art has a full range of features including weather resistance such as a dust and splash resistant structure* and water and oil repellent coating, as well as a zoom lock switch. The lens delivers the best possible results in every shooting situation.
* The structure is designed to be dust and splash resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.
