24-70mm F2.8 (A) DG DN II E-Mount Lens for Sony (Black) - SIGMA

Description
The SIGMA 24-70mm F2.8 DG DN II / Art is SIGMA’s flagship lens that has evolved significantly from its predecessor, incorporating the most advanced technologies available to SIGMA, from design to production. Compared to the previous SIGMA 24-70mm F2.8 DG DN II / Art, the new SIGMA 24-70mm F2.8 DG DN II / Art has improved resolving power across the entire zoom range and also benefits from functional improvements 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, 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 renowned for its high optical performance, and has further improved resolution across the entire zoom range. The lens delivers high sharpness across the entire image from its widest aperture, even on high-resolution cameras. With a focus on improving its rendering performance, the bright F2.8 aperture produces large and beautiful bokeh and allows users to experience the power of a prime 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, delivering ideal images in any situation.

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

Incorporates 5 aspherical lenses
The use of 5 high-precision aspherical lenses enables high optical performance with minimal aberration correction and a compact optical design. SIGMA’s sole 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 to the construction of this lens. This has brought a greater 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 to the subject.

* Be very careful not to let the front lens element hit the subject when shooting. Remove the lens hood when shooting at the minimum focusing distance at the wide end.

Designed to minimize flare and ghosting
Flare and ghosting, which reduce image quality, have been largely eliminated through advanced simulation technology, ensuring that 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 maximum degree. High resistance to backlighting enables sharp, clear images in any lighting conditions.

Minimal focus breathing
The lens is designed to suppress focus breathing. The change in angle of view due to focus shift throughout the zoom range is minimized, creating natural-looking focus during video recording.

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

Excellent build quality
With a simultaneous focus 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 pressing the lensgar the lens. The design emphasizes the longevity and reliability of the lens as a tool, which cannot be achieved by pursuing a compact and lightweight body alone.

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, enabling aperture operation suitable for various shooting situations.

Equipped with two AFL buttons
The lens is equipped with two AFL buttons*, which can be assigned a range of functions via the menu of 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 only be assigned on supported cameras. Available functions may vary depending on the camera used.

A wide range 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 / A art has a full range of features including weather resistance, such as a dust- and splash-resistant body* and water- and oil-repellent coating, as well as a zoom lock switch. The lens delivers the best possible results in all shooting situations.
* The body is designed to be dust- and splash-resistant, but not waterproof. Be careful not to expose the lens to large amounts of water. Water inside the lens can cause serious damage and even render the lens unrepairable.

Built-in HLA linear motor
The lens incorporates an HLA (High-response Linear Actuator) linear motor for the AF actuator. The high-output HLA makes the unit’s top speed more than three times faster than the previous model*, ensuring responsive AF shooting.

Dust- and splash-resistant structure and water- and oil-repellent coating
In addition to a dust- and splash-resistant structure, the front lens element features a water- and oil-repellent coating, allowing users to shoot worry-free even in harsh outdoor environments.

Equipped with a zoom lock switch at the wide end
The lens is equipped with a zoom lock switch that locks the lens at the wide end and prevents the barrel from unintentionally extending under its own weight. The lock can be released not only by the switch but also by zoom operation, allowing flexible handling even for impromptu shooting.

Including a petal-type lens hood with lock
A dedicated petal-shaped lens hood with a locking mechanism for secure attachment.
