Sigma 12-24mm f/4 DG HSM Art Lens

The third incarnation of the Sigma 12-24mm f/4 DG HSM Art Lens, available with mounts for Canon EF, Nikon F, or Sigma SA, refines their ultra-wide lens and offers up a picture with very little distortion and with a high resolution for fresh photographs with a cutting edge full-frame digital image sensor. A member from the Sigma Art series, it features high image quality which is assisted by the utilization of FLD and aspherical elements, including a 80mm huge diameter molded glasses aspherical lens, that minimizes distortions and aberrations. Besides, it utilizes a Super Multi-Layer covering that minimizes flare and ghosting.

Taking advantage of handling, the 12-24mm is furnished with a Hyper Sonic AF motor with an improved algorithm for speed and precision. The lens additionally provides a substantial focusing ring with full-time manual override settings for rapidly making adjustments. A 9-blade rounded diaphragm enhances picture quality by making smooth bokeh while the lens is built from a lightweight and sturdy thermally-stable composite. Likewise, the 12-24mm has an all brass bayonet lens mount and is both splash and dust proof. What's more, it is completely compatible with the Sigma USB Dock.

As a member of the Art line within Sigma's Global Vision line, this lens' is engineered to achieve truly distinguished optical performance and is ideal for artistic and creative applications.

This wide-angle 12-24mm f/4 zoom lens is created for full-frame format Canon EF, Nikon F and Sigma SA-mount cameras, and can also be mounted on APS-C versions where it will deliver a 19.2-38.4mm focal length equivalent.

Constant f/4 maximum aperture delivers consistent performance all through the entire zoom range. Aspeherical and F Low Dispersion elements, which includes a molded glass 80mm large-diameter aspherical element, have been made a part of the lens design to minimize chromatic aberrations through the entire focusing range and to ensure high image clarity, sharpness, and contrast regardless of aperture setting or focus point. This optical layout also helps to handle distortion and limit vignetting.

Also applied to lens elements is a Super Multi-Layer Coating as a way to cut down on lens flare and ghosting and make a contribution to delivering contrast-rich and color-neutral images, even in backlit situations.

An integrated HSM (Hyper Sonic Motor) is quick with quiet autofocusing, which is additionally complemented by an optimized AF algorithm to provide smoother focusing operation.

The HSM also offers full-time manual focus override by simply rotating the focus ring during any time. Minimum focus distance of 9.4" when photographing at 24mm for getting up close to your subjects.

A nine-blade rounded diaphragm helps to create an attractive out-of-focus quality.

The lens is manufactured using a Thermally Stable Composite material (TSC), along with traditional metals, for greater fidelity and use in a wide array of temperature variations.

The bayonet mount is made of brass for ensured accuracy and durability.

Splash and dust-proof construction using rubber sealing to protect the mount while a water- and oil-repellent coating is used on the front and rear elements.

The lens is compatible with the available Sigma USB Dock for fine-tuning characteristics of different lenses and updating firmware.
