Sigma 24-70mm

A versatile zoom for everyday shooting, the Canon EF-mount 24-70mm f2.8 DG OS HSM Lens from Sigma covers a useful wide-angle to portrait-length range of focal lengths to suit shooting in a variety of environments.

As part of the esteemed Art series of lenses, a sophisticated optical design is used that incorporates three SLD elements and four aspherical elements to reduce chromatic and spherical aberrations, as well as colour fringing, distortions, and other anomalies for greater clarity and sharpness.

A Super Multi-Layer Coating has also been applied to suppress lens flare and ghosting for accurate colour fidelity and high contrast, and a protective coating has been applied to the front element, too, to benefit working in harsh climates. Additionally, extending its versatility, a constant f2.8 maximum aperture affords consistent performance throughout the zoom range as well as greater control over depth of field.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override.

An Optical Stabilizer also benefits handheld shooting by minimizing the appearance of camera shake for sharper imagery. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision.

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
• Standard zoom lens is designed for full-frame-format Canon EF-mount DSLRs, however it can also be used with APS-C models where it will provide a 38.4-112mm equivalent focal length range.
• Constant f2.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
• Three Special Low Dispersion (SLD) elements and four aspherical elements are featured in the optical design and help to reduce colour fringing and chromatic aberrations for improved clarity and colour accuracy, as well as spherical aberrations for reduced distortion and improved sharpness throughout the zoom range.
• A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and colour-neutral imagery, even in backlit conditions.
• Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
• Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
• The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
• Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
• The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• The Canon EF-mount 24-70mm f2.8 lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

Top-Level Performance Optimised for the Era of Ultra-High-Megapixel Cameras

The Sigma 24-70mm f2.8 DG HSM OS Art is a premium workhorse zoom lens designed for the latest high-megapixel DSLRs. A constant aperture of f2.8 through the zoom range make this a highly versatile tool and a brand new Optical Stabilisation (OS) system help compensate for camera shake. Though a common focal length, the Sigma 24-70mm Art brings a new level of usability and durability featuring a rugged metal barrel and an emphasis on image quality.

Building off the experience from the 12-24mm Art, the aspherical elements used in the 24-70mm f2.8 OS Art undergo a highly precise level of polishing producing elements thicker in the centre than on the edges.

This process creates stunning image quality and beautiful circular bokeh. Like each and every Global Vision Lens, the Sigma 24-70mm f2.8 DG HSM OS Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma's facility.

Landscapes to Portraits, All with Exceptional Optical Quality

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimise optical aberrations. To ensure outstanding image quality from the centre to the edges of the photograph, the optical system minimises coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control,

The optical system also minimises distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

Capture Beautiful Portrait Photographs with a Bokeh that is a Cut Above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful 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 perfect circularity. 

OS Functionality and Newly Designed HSM for Success on any Shoot

Designed for advanced utility in a wide variety of situations, the optical stabiliser (OS) offers a powerful stabilisation effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

Lens Barrel Designed for high Rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm f2.8 DG HSM Art is designed to stand up to the challenging shooting environments that pros encounter.
