14-24mm F2.8 DG DN

Ultimate large-diameter, wide-angle zoom lens optimized
for full-frame mirrorless cameras
−“The definitive lens for astrophotography”
with astonishing resolution.

Many photographers like to use low sensitivity shooting to minimize noise as much as they can. Particularly in the photography of starry skies, bright wide-angle lenses are often selected because they can efficiently collect weak light. The 14-24mm F2.8 DG DN | Art has been developed as the ultimate large-diameter, wide-angle zoom lens by optimizing the standard specifications for photographing starry skies for full-frame mirrorless cameras. The uniform rendering performance and outstanding resolution to the edge of the frame make it the “definitive lens for astrophotography.” By utilizing the characteristics of the short flange focal length, this new-generation large-diameter zoom lens combines both compact body and unprecedented high-resolution image quality.

About Product Name:
Product name includes “DG” when the lens is designed to deliver the ultimate in performance on cameras with full-frame sensors, and “DN” when the lens design is optimized for mirrorless cameras with the short flange focal length.

Newly developed high-performance lens series for full-frame mirrorless cameras

With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. SIGMA has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.

SIGMA will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.” We will announce three models as the first lenses from this series.

45mm F2.8 DG DN | Contemporary

Compact size is realised while maintaining high image quality and is compatible with full-frame mirrorless cameras. This prime lens refines the concept of the Contemporary line.

341_feature02_main_img02

35mm F1.2 DG DN | Art

The world’s first* 35mm F1.2 as L-Mount and Sony E-mount lens for full-frame mirrorless system.  The high image quality of the Art line that pursues ultimate performance is realized by F1.2 maximum aperture.

341_feature02_main_img03

14-24mm F2.8 DG DN | Art

Large-diameter, ultra-wide-angle zoom lens for full-frame mirrorless cameras.  While pursuing the ultimate image quality of the Art line, the size is reduced thanks to the exclusive design for mirrorless cameras.

feature-image-213

High-resolution image quality developed
with exclusive low dispersion glass elements and NPC
(Nano Porous Coating)*

One FLD glass and five SLD glass elements are appropriately arranged to suppress chromatic aberration to the edge of the frame. Three aspherical lenses, including a large-diameter aspherical lens at the foremost surface, are used to effectively minimize coma flare, etc., thereby achieving mind-blowing resolution. The super multi-layer coating is combined with a newly developed NPC (Nano Porous Coating)*. The lens has been designed to be less susceptible to strong incident light such as backlight.

* SIGMA’s new unique coating technology “NPC (Nano Porous Coating)” incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.

Substantial functions enable user confidence, even in tough environments

Incorporating a stepping motor enables the high speed, quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.

Rear filter holder as a standard accessory

The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies..

Other features

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as back lighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in back light conditions.

Fast AF with full-time manual focus

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Note: The operation of full-time MF may vary based on mount type.

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

Rounded diaphragm (11-blade)

The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

ESSENTIALS

You'll find our philosophy and craftsmanship in every product

Our new lineup fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art, or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality, and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product.

Evaluation with Sigma's own MTF measuring system “A1”

We used to measure lens performance with MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 50mm F1.4 DG HSM will all be checked using this “A1” before they are shipped.
