SIGMA 24-70mm F2.8 DG DN II | Art – L Mount

Overview
The SIGMA 14-24mm F2.8 DG DN | Art lens boasts a lens construction of 19 elements in 15 groups, including 6 FLD, 2 SLD, and 5 aspherical elements. It features an inner focus system and is compatible with high-speed autofocus, thanks to the HLA (High-response Linear Actuator). The lens is also compatible with Lens Aberration Correction, although the available corrections may vary depending on the camera model. On cameras where lens aberration correction is controlled with ON or OFF in the camera menu, it is recommended to set all aberration correction functions to ON (AUTO).

In addition, the lens supports DMF and AF+MF, as well as AF assist (for Sony E-mount only). It also features Nano Porous Coating, Super Multi-Layer Coating, a water- and oil-repellent coating on the front element, an aperture ring with click switch and lock switch, and an AFL button. The lens also has a Focus Mode switch and supports switching between linear and non-linear focus ring settings (for L-Mount only). It has a dust- and splash-resistant structure and comes with a petal-type hood with lock LH875-05. The lens is also compatible with the SIGMA USB DOCK UD-11 (sold separately, for L-Mount only) and is designed to minimize flare and ghosting. It also undergoes SIGMAs proprietary MTF measuring system and has an 11-blade rounded diaphragm, high-precision, durable brass bayonet mount, and Mount Conversion Service available. Made in Aizu, Japan, this lens offers high optical performance across the entire image and zoom range.

About the SIGMA 24-70mm F2.8 DG DN II | Art – L Mount
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 colour 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 moulding 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.

* 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.

Highly portable 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.*

* These figures are for L-Mount.

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.

* Functions can be assigned on supported cameras only. Available functions may vary depending on the camera used.

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.

* Compared by the maximum drive speed of the SIGMA 24-70mm F2.8 DG DN II | Art with that of the SIGMA 24-70mm F2.8 DG DN | Art (It is different from the actual time for AF to focus).

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.
