Sigmas dynamic 24-70mm F2.8 DG HSM OS Art Lens

The Sigma 14mm F1.8 Art, which is the first and only F1.8 ultra wide-angle lens among interchangeable lenses for digital SLRs*, incorporates the same aspherical element as Sigma's critically acclaimed 12-24mm F4 Art, allowing the lens to deliver a new dimension of visual experience. Boasting outstanding image quality from center to edge, the 14mm F1.8 Art features an 80mm front lens - the world's largest glass aspherical lens in the industry, offering photographers an ultra-wide prime with virtually no distortion, flare or ghosting. Equipped with a superfast and efficient autofocus system, three FLD ( F Low Dispersion) elements, and four SLD (Special Low Dispersion) elements to reduce chromatic aberration and coma flare, the 14mm F1.8 Art is suitable for a wide range of photographic needs including astrophotography, architecture and landscape photography.

The 24-70mm F2.8 Art lens, Sigma's new workhorse standard zoom lens, touts a brand new Optical Stabilizer (OS), Hypersonic Motor (HSM) for highly efficient and fast autofocus, as well as a dust- and splash-proof mount with rubber sealing. The 24-70mm F2.8 Art lens embodies all the technical qualities and finesse that define the high-performance Sigma Global Vision Art series. A popular industry focal range covering a wide array of shooting scenarios, the 24-70mm's optical design also includes three SLD (Special Low Dispersion) glass elements and four aspherical elements to ensure image accuracy and sharpness. The 24-70mm F2.8 Art aspherical elements use Sigma's thicker center glass design and highly precise polishing process, delivering stunning images and bokeh effects. The lens' purpose-built structure boasts a new metal barrel for optimal durability with TSC composite internal moving components designed to resist thermal contraction and expansion.

Both the 14mm F1.8 DG HSM and the 24-70mm F2.8 DG OS HSM Art lenses are available in Canon, Nikon and Sigma mounts. The Sigma and Canon mount lenses work with Sigma's MC-11 Sony E-mount converter. The Nikon mounts feature the brand new electromagnetic diaphragm.

Sigma 14mm F1.8 DG HSM Art Lens Features and Benefits:

> Sharp, rich image quality

Minimized chromatic aberrations: Three FLD ( F Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help reduce transverse chromatic aberration, which tends to be noticeable in shots taken with ultra wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.

Distinctive bokeh effect: Even at the 14mm ultra wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a pleasingly softened background. It's the unique mode of expression that only a large-diameter lens can deliver.

Minimized distortion: Serving as the front lens element, the large 80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

> Offers full-frame coverage

Sigma 24-70mm F2.8 DG HSM OS Art Lens Features and Benefits:

> Superior optical performance

Optimal image quality for ultra-high-megapixel DSLRs: This lens offers top performance from the center to the edges of the image thanks to the optical system minimizing coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control. The optical system also minimizes distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

Expressive bokeh effect every time: At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful, creamy bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, Sigma has paid close attention to the shape of the bokeh, aiming for artistic circularity.

Aspherical Lens Processing Technology: The Sigma 24-70mm F2.8 DG OS HSM Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology. Moreover, Sigma processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the Sigma 24-70mm F2.8 DG OS HSM Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

> Fast and nimble autofocus photography

Designed for advanced utility in a wide variety of situations, the optical stabilizer (OS) offers a powerful stabilization effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor for exceptionally stable performance.
