SIGMA Camera Lens 24-70mm F2.8 DG DN II Art [Leica L / zoom lens]

Product Specifications

Basic Information

Product Features

The 24-70mm F2.8 Art zoom lens has evolved in all aspects: descriptive performance, functionality, and portability.
Sigma's flagship lens has undergone an all-around evolution by incorporating the most advanced technologies available to Sigma in all processes from design to production. The resolution has been improved from the previous model across the entire zoom range. In addition to functional enhancements such as an additional aperture ring and high-speed AF with a new HLA AF actuator, the lens is also smaller and lighter, by approximately 7% in volume and 10% in weight. In addition, it is approximately 7% smaller and 10% lighter than its predecessor in terms of volume and weight, respectively.

1. Descriptive power 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 resolving power throughout the entire zoom range. The lens has high sharpness throughout the entire image from the maximum aperture, even on high-resolution cameras, and the brightness of F2.8 creates a large, beautiful bokeh effect, and other descriptive features that allow you to experience the power of a flagship lens in every expression. In addition to its advanced close-up shooting ability and flare and ghosting resistance, the lens is designed to minimize focus breathing, providing ideal images in any situation.

High optical performance throughout the entire image and zoom range
Six FLD glass elements, two SLD glass elements, and five aspherical lens elements are used to thoroughly suppress various aberrations throughout the entire zoom range. In particular, sagittal coma flare has been suppressed to achieve stable high resolution all the way to the periphery of the image. By also compensating for magnification chromatic aberration, the lens delivers a clear image with high resolution and no color blurring.

Five aspherical lenses are used
The use of five high-precision aspherical lens elements enables both high optical performance with excellent aberration correction and a compact optical system. Continuous technological innovation has realized the thin and highly polarized aspherical molding that is essential for this configuration, which is difficult to achieve.

High close-up shooting ability
The lens offers high close-up shooting ability, with a minimum focusing distance of 17 cm at the wide end and a maximum magnification of 1:2.7.

Flare and ghosting
To prevent flare and ghosting, which reduce image quality, the lens is designed to handle all conditions of incident light based on state-of-the-art simulation technology. In addition, the use of nano-porous coating and super multi-layer coating suppresses flare and ghosting to the utmost limit. High backlight resistance enables clear and sharp images under any lighting conditions.

Designed to suppress focus breathing
The lens is designed to suppress focus breathing. The angle of view changes little as the focus shifts throughout the entire zoom range, enabling natural expression of focus shift in movie shooting. 2.

2. multifunctional and compact/lightweighted at the same time compared to previous models
The lens body of the SIGMA 24-70mm F2.8 DG DN II Art is approximately 7% smaller and 10% lighter than its predecessor in terms of volume and weight, while enhancing functionality with the addition of an aperture ring and two AFL buttons.

Highly portable lens body
While the number of lens elements is the same as that of the previous model, the overall length has been shortened through advanced optical design. In addition, the mechanical design has been thoroughly streamlined to achieve a highly portable lens body with a maximum diameter of 87.8 mm, a length of 120.2 mm, and a weight of 745 g.

High build quality in a compact and lightweight body
While focusing on reducing the size and weight of the lens body, the use of metal parts for the zoom extension and other parts and the robust internal structure ensure rigidity during use, such as when operating the ring, pressing buttons, and carrying the lens.

Equipped with an aperture ring
Equipped with an aperture ring. An aperture ring click switch and aperture ring lock switch are also provided, allowing aperture operation according to the shooting application.

Two AFL buttons
Two AFL buttons are provided to which any desired function can be assigned.

Various functions including high-speed AF
In addition to high-speed AF using a high-response linear actuator (HLA), the camera is equipped with a full range of functions, including dust-proof and drip-proof construction, weather resistance with a water and stain repellent coating, and a zoom lock switch.

Adoption of linear motor HLA
A linear motor HLA (High-response Linear Actuator) is used as the AF actuator. The maximum drive speed is more than three times faster than that of conventional models.

Dustproof and drip-proof construction with water and stain repellent coatings
The lens is dustproof and drip-proof, and the front-most surface of the lens is coated with a water- and stain-repellent coating.

Zoom lock switch (wide end)
The zoom lock switch locks the lens at the wide end to prevent unintended zooming due to its own weight. The lock can be released not only by the switch but also by zoom operation.
