Description
The Art 24-70mm F2.8, evolved on all levels: rendering performance, functionality, and portability
The SIGMA 24-70mm F2.8 DG DN II | Art is SIGMA’s flagship lens that has evolved significantly from the previous model by incorporating the most advanced technologies available to SIGMA from design to production. Compared to it’s predecessor, the SIGMA 24-70mm F2.8 DG DN II | Art has improved resolving power throughout the entire zoom range, and also benefits from functional enhancements such as the addition of an aperture ring and high-speed AF with a redesigned AF motor and HLA (High-response Linear Actuator). The lens is also approximately 7% smaller and 10% lighter. This 24 70mm F2.8 Art zoom is a versatile and high-performance tool that will help photographers and filmmakers unlock their creative potential.
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. The optical design of the lens thoroughly suppresses 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. 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, 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.
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.
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 lens coating. The lens is equipped with a zoom lock switch that locks the lens at the wide end and prevents the barrel from extending unintentionally under its own weight, delivering the best possible results in every shooting situation.
