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. 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.
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.
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.
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.
