Sigma's widest ultra-wide-angle zoom
Designed for use with full-frame DSLRs, the 12-24mm is a wide-angle zoom that offers an exceptionally wide focal length for anyone needing a very wide angle-of-view. The lens is perfect for landscape photography, interiors, events and architecture, and the constant F4 aperture provides fast shutter speeds in low light.
Optically the lens is extremely impressive, delivering edge-to-edge sharpness even at 12mm, allowing photographers to capture scenes in remarkable detail, even on the highest resolution DSLR cameras. This is thanks to its advanced optical design that includes 5 FLD elements, 1 SLD element and 2 aspherical elements.
The SIGMA 12-24mm F4 lens also features a durable and weather-resistant design, making it suitable for use in a variety of shooting conditions.
The 12-24mm boasts one of the widest focal lengths on the market, and is perfect for architecture, interiors and landscapes.
Precision brass mount with seal
Protects against dust and moisture.
Zoom ring
With smooth and accurate movement.
Focus Mode switch

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.
SIGMA’s unique coating technology Nano Porous Coating
The super multi-layer coating is combined with SIGMA’s unique coating technology “NPC (Nano Porous Coating)”. The lens has been designed to be less susceptible to strong incident light such as backlight.
“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.
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 backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
Rounded diaphragm
The 11-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
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.
- Note:
・Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
・On cameras where lens aberration correction is controlled with ‘ON’ or ‘OFF’ in the camera menu, please set all aberration correction functions to ‘ON'(AUTO).
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.
Description
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.

VIEWFINDER OPTIONS
Two wide-angle zooms for DSLRs
The 12-24mm and 14-24mm are SIGMA’s two widest-angle full-frame zooms for DSLRs. With exactly the same weight, AF motor and maximum aperture, and near identical build quality, length and optical designs, they are very similar lenses. The main differences are F2.8 aperture of the 14-24mm, and the wider angle-of-view of the 12-24mm.

Made in Aizu
All Sigma cameras and lenses are designed, manufactured and assembled at our sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
Sigma chose Aizu as its main production base in the early 1970s. Situated at the base of Mount Bandai in the Fukushima Prefecture, about four hours’ drive north of Tokyo, Aizu has an
