Sigma 24-70mm f/2.8 DG OS HSM Art Lens for Canon EF

HIGHLIGHTS

• EF-Mount Lens/Full-Frame Format
• Aperture Range: f/2.8 to f/22
• Three SLD Elements

Four Aspherical Elements

• 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 Canon EF-mount cameras, however it can also be used with APS-C models where it will provide a 38.4-112mm equivalent focal length range.
• Constant f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over depth of field when using shallow depth of field techniques.
• Three Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
• Four aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
• 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 color-neutral imagery, even in backlit conditions.
• Integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocus, 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 by up to four stops to benefit making sharper imagery when shooting handheld.
• Rounded nine-blade diaphragm is constructed from durable, fluorine-coated polycarbonate and also features a carbon feather film for smooth performance when working with fast continuous shooting rates.
• Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
• Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
