Sigma 24-70MM F/2.8 DG DN II ART L-MOUNT

Sigma 24-70MM F/2.8 DG DN II ART L-MOUNT. 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 the previous SIGMA 24-70mm F2.8 DG DN Art, 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, 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.

 

 

 

 

HIGH OPTICAL PERFORMANCE

 

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. * 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.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

EQIUIPPED 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.
