The Canon EF-mount 150-600mm f/5-6.3 DG OS HSM from Sigma is a Contemporary-series telephoto zoom characterized by its sophisticated optics and flexible handling. One FLD element and three SLD elements are used to reduce color fringing and chromatic aberrations throughout the zoom range and a Super Multi-Coating also helps to suppress flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. An Optical Stabilizer also works to minimize the appearance of camera shake for sharper handheld shooting. Additionally, a removable, rotating tripod collar is included to suit working atop a tripod or monopod. As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance and meshes a compact, lightweight build and versatile handling with notable optical attributes. One F Low Dispersion (FLD) and three Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. 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. Dust- and splash-resistant design suits this lens's use in inclement weather conditions and a water- and oil-repellent coating has also been applied to the front element to aid in cleaning. 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. A removable, rotating tripod collar offers well-balanced support for photographing atop a tripod or monopod with either vertical or horizontal shooting orientations.

Optimized for Canon EF-mount lenses in the Global Vision line, the TC-1401 1.4x Teleconverter from Sigma will offer an increase in focal length of 1.4 times for select Global Vision lenses. This model offers full communication between the lens and camera and will allow autofocus to operate up to f/8. The teleconverter also features one Special Low Dispersion element for reducing the appearance of chromatic aberrations and maintaining quality. Additionally, for protection, the TC-1401 is both dust and splashproof. When attached, the 1.4x conversion results in a light loss of approximately one stop.
