Sigma 70-200mm f/2.8 DG OS HSM Sports Lens - Canon

The technical details behind this lens
Sigma 70-200mm f/2.8 DG OS HSM Sports Lens - Canon offers a great optical design and performance. This lens is a flexible telephoto zoom distinguished by its sophisticated and bright design. It features a fast constant f/2.8 maximum aperture that excels in difficult lighting conditions and delivers increased control over the depth of field for isolating subjects. In regard to the optical layout, an impressive 10 low dispersion elements are used to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. A Super Multi-Layer Coating is offered and helps to suppress ghosting and flare when working in strong lighting conditions. Complementing the optics is an Intelligent OS system, which minimizes the appearance of camera shake for sharper outputs when shooting handheld. A Hyper Sonic Motor is used to provide quick and quiet autofocus performance along with full-time manual focus override. The physical design of the lens incorporates several seals to guard against dust and moisture, and a water- and oil-repellent coating has been applied to the exposed elements to prevent moisture, fingerprints, or smudges from sticking to the surface. A fixed rotating tripod collar is featured and has a removable Arca-type compatible foot for wide compatibility with a different tripod or monopod heads. It also offers a Dust- and Moisture-Sealed Construction.
Impressive Optical Performance
This lens is designed to provide excellent optical performance, speed, and other customizable features that make it a perfect choice for wildlife, sports, action, and other fast-moving subjects. Versatile telephoto zoom is designed for full-frame Canon EF-mount cameras, however is also suitable for APS-C models where it provides a 112-320mm equivalent focal length range. The constant f/2.8 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. One Special Low Dispersion (SLD) element and nine 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, 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 color-neutral imagery, even in backlit conditions. The rounded 11-blade diaphragm contributes to a smooth and pleasing bokeh quality.
Great Features
The Front and rear lens elements have been treated with a water- and oil-repellent coating to benefit from working in trying environmental conditions. 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. An Intelligent Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld. Tripod collar has a rotating design and the replaceable foot is Arca-type compatible for easy mounting.
Accuracy and Durability
The bayonet mount is constructed from brass for ensured accuracy and durability. In addition, the rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
Compatibility
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware. It is also compatible with optional Sigma 1.4x and 2x teleconverters.
