Product Description
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 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 factorys 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 SIGMAs 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.
