"The Sigma 17-70mm f/2.8-4 DC Macro OS HSM Lens for Canon is a standard zoom lens designed especially for DSLRs with APS-C-sized image sensors. This lens has a 35mm-equivalent focal length range of 27.2-112mm, providing wide-angle to portrait-length angles of view for use in everyday shooting situations.This lens features a fast f/2.8-4 maximum aperture to help better control your focus plane and to aid in low-light shooting. A built-in Optical Stabilizer also helps in low-light situations by providing a four-stop reduction in the appearance of camera shake, which is ideally suited for macro and telephoto shooting as well. The Hyper Sonic AF Motor delivers fast, smooth, and quiet auto focusing that greatly benefits video applications. The integration of two FLD, one SLD, and three aspherical lenses in the construction helps to reduce the effects of chromatic and chromatic axial aberrations, and Super Multi-Layer coated elements help to increase contrast for sharp, clear imagery.As part of Sigma's new Contemporary line of lenses, this lens is designed using Thermally Stable Composite (TSC) materials to help reduce the overall weight and size of the lens barrel by about 30% without compromising on optical integrity, rigidity, or overall durability.For updating lens firmware and fine-tuning its nuances to best-suit your personal shooting, this lens is compatible with the Sigma USB Dock. The dock allows you to specify certain parameters and other settings through the Sigma Optimization Pro software, such as AF speed and focusing limitations."

"Sigma Art 35mm f/1.4 DG HSM Lens Nikon F (FX)"
"The 35mm f/1.4 DG HSM Lens for Nikon DSLR Cameras from Sigma is the first entry into Sigma's Art series of professional lenses, with an emphasis on artistic expression and the creative potential of the lens. With a bright f/1.4 maximum aperture, floating inner focusing system, and Hyper Sonic Motor (HSM) you'll have quick and accurate control over the artistic effects achieved by the lens' high quality elements.For wide angle photography, this 35mm lens and its circular 9-bladed f/1.4 aperture ensure excellent brightness and blurred background (bokeh) effects. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.The lens' Hyper Sonic Motor (HSM) and floating inner focusing system ensure that you experience quick, quiet and precise autofocusing whenever you need it. Adjust focus using either autofocus (AF), or full-time manual focus, without having to switch camera modes or change settings - just flick the switch from AF to MF.For greater build quality and strength, all metallic parts and the new Thermally Stable Composite compound material (TSC), are housed internally. Its brass made bayonet mount has both high accuracy and durability, and a special treatment is applied to its surface giving it greater strength and making it highly resistant to long-term daily use."

"Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary Lens - Nikon"
"An all-in-one zoom for APS-C cameras, the Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM Contemporary Lens provides users with an extremely versatile focal length equivalent of 28.8-480mm. This version also offers optical image stabilization for reducing the effects of camera shake at longer focal lengths and slower shutter speeds. The lens also has a maximum aperture range of f/3.5-6.3 and benefits from the inclusion of one SLD and four FLD elements. Additionally, a Super Multi-Layer coating on the elements results in less flare and improved contrast. Utilizing a Hyper Sonic Motor for autofocus ensures quick, quiet, and accurate focusing, all the way to the lens' minimum focus distance of just 15"". A lens hood is included with the lens and it is compatible with Sigma's USB Dock for installing firmware updates and adjusting focus. Lens construction with 17 elements in 13 groups Super Multi-Layer Coating reduces flare and ghosting for higher contrast images ""F"" Low Dispersion, or FLD, glass is designed with performance similar to flourite elements with a low refractive index and low dispersion for minimizing chromatic aberration as well as clearer and sharper imagery Special Low Dispersion, or SLD, glass elements assist in providing greater clarity and contrast to an image Maximum magnification ratio of 1:3 or 1:2 with optional AML72-01 close-up lens Features a front 72mm filter thread   "

"Sigma ART 24mm f/1.4 DG HSM Lenses - Canon Mount"
"A wide and fast Canon EF-mount prime, the 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma's Global Vision Series and is characterized by its advanced optical construction and robust physical design. The combination of three ""F"" Low Dispersion (FLD) elements and four Special Low Dispersion elements help to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control. Nine rounded diaphragm blades contribute to pleasing out-of-focus quality when working with shallow depth of field techniques, and the lens is also compatible with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics."
