SIGMA Camera Lens 24-70mm F2.8 DG DN II Art Line Interchangeable Lens for Sony E-Mount

[Product Features]

◆ 2470mm F2.8 Art zoom with improved imaging power, functionality, and portability

This flagship lens has evolved in every direction by applying SIGMA's cutting-edge technology to every process, from design to production.
Resolution has been improved across the entire zoom range compared to previous models.
Furthermore, in addition to enhancing functionality such as the addition of an aperture ring and high-speed AF with an all-new AF actuator, HLA, the camera has also been made smaller and lighter, with a volume ratio of approximately 7% and a weight ratio of approximately 10%.
It demonstrates its true value in any field, whether for still images or videos.

◆Depiction capabilities worthy of the flagship name

The SIGMA 2470mm F2.8 DG DN II Art is the successor to the SIGMA 2470mm F2.8 DG DN Art, which is characterized by its high optical performance, and offers improved resolution across the entire zoom range.
It has high sharpness across the entire screen from wide open aperture, making it compatible with high pixel cameras.
It also focuses on image quality, such as the large, beautiful bokeh created by the brightness of F2.8, and boasts the performance to allow you to experience the power of a flagship lens in all expressions.
In addition to its advanced close-up shooting capabilities and resistance to flare and ghosting, the lens is designed to suppress focus breathing, providing ideal images in any situation.

◆High optical performance across the entire screen and zoom range

Six FLD glass elements, two SLD glass elements, and five aspherical lenses are used to thoroughly suppress various aberrations across the entire zoom range.
In particular, by suppressing sagittal coma flare, consistently high resolution is achieved even at the edges of the screen.
By effectively correcting lateral chromatic aberration, you can enjoy high resolution with clear images free of color bleeding.

◆ 5 aspherical lenses

By using five high-precision aspherical lenses, we have achieved both high optical performance with excellent aberration correction and a compact optical system.
Continuous technological innovation has made it possible to achieve the highly challenging aspheric molding required for this structure, with its thinness and high thickness deviation.

◆High close-up shooting ability

It has a minimum shooting distance of 17cm on the wide-angle side and a maximum shooting magnification of 1:2.7, providing excellent close-up shooting capabilities.

◆ Designed to reduce flare and ghosting

Regarding flare and ghosting, which degrade image quality, we have taken measures based on cutting-edge simulation technology to deal with incident light under all kinds of conditions.
In addition, by applying a nanoporous coating and super multi-layer coating, flare and ghosting are suppressed to the utmost extent.
High resistance to backlight allows for clear, sharp shots in any lighting conditions.

◆Designed to reduce focus breathing

The design takes into consideration the suppression of focus breathing.
Since there is little change in the angle of view due to focus shifting across the entire zoom range, natural focus shifting can be achieved when shooting video.

◆ Achieves greater functionality and smaller size and weight than previous models

The SIGMA 2470mm F2.8 DG DN II Art lens body has been made smaller and lighter by approximately 7% in volume and 10% in weight compared to previous models, while also enhancing functionality by adding an aperture ring and two AFL buttons.

◆Highly portable lens body

While the number of lens elements is the same as previous models, the overall length has been shortened thanks to an improved optical design.
Furthermore, the mechanical design has been thoroughly streamlined to achieve a highly portable lens body with a maximum diameter of 87.8 mm, length of 120.2 mm and a weight of 745 g.

◆Small and lightweight body with high build quality

While much effort was put into making the lens body smaller and lighter, the use of metal parts for the zoom mechanism and other parts, as well as a robust internal structure, ensures a sense of rigidity when operating the ring, pressing buttons, and carrying the lens.

◆ Equipped with aperture ring
Equipped with an aperture ring.
It also features an aperture ring click switch and an aperture ring lock switch, allowing you to adjust the aperture to suit your shooting needs.

◆ Equipped with two AFL buttons

Equipped with two AFL buttons to which any function can be assigned.

◆Full range of functions including high-speed AF

In addition to high-speed AF using an HLA (High response Linear Actuator), the camera is equipped with a variety of useful functions, including weather resistance thanks to its dust-proof and drip-proof construction, water-repellent and dirt-resistant coating, and a zoom lock switch.

◆ Linear motor HLA adopted

The AF actuator uses a linear motor, HLA (High response Linear Actuator).
The maximum drive speed is more than three times faster than previous models.

◆Dust-proof, drip-proof construction and water-repellent, dirt-resistant coating

It is dust-proof and weather-resistant, and the front lens is coated with a water-repellent and dirt-resistant coating.

Equipped with a zoom lock switch (wide side)

Equipped with a zoom lock switch that locks at the wide-angle end to prevent unintentional zoom movement due to the lens's own weight.
The lock can be released not only by the switch but also by zooming.
