• All-in-one zoom is designed for DX-format Canon EF-mount cameras, and provides a 27-450mm equivalent focal length range.

• One Special Low Dispersion (SLD) and Four F Low Dispersion (FLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.

• Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall 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.

• Ideal for close-up shooting, this lens offers a 1:3 maximum magnification along with a minimum focusing distance of 1.3′ to suit working with nearby subjects.

• Integrated HSM (Hyper Sonic Motor), along with a rear focus system, 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 to benefit making sharper imagery when shooting handheld.

• Rounded seven-blade diaphragm contributes to a smooth and pleasing bokeh quality.

• 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.

• Zoom lock switch helps to prevent accidental and unwanted zoom adjustment.

• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
