Product Details
Sigma 57A965 Camera Lens 24-70mm f/2.8 DG DN II Art for Sony E-Mount in Black
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.
Features
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 /
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.
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.
High Portability 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.
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.
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.
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.
Incorporating A Linear Motor HLA
The lens incorporates a linear motor HLA (High-response Linear Actuator) for the AF
actuator. The high output HLA makes the maximum drive 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 element of the lens features
a water and oil repellent coating, allowing users to shoot without concerns 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 extending unintentionally under its own weight. The lock can be
released not only by the switch but also via zoom operation, allowing for flexible handling
of even impromptu shooting.
Including A Petal-Type Hood With Lock
A dedicated petal-shaped hood is supplied. A locking mechanism is provided for secure
attachment.
