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 Stabiliser 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 Optimisation Pro software, such as AF speed and focusing limitations.
Contemporary Lens Line
This lens is the first lens produced as part of Sigma's Contemporary line; deeming it lightweight and compact while still exhibiting high optical performance. This lens' wide range of focal lengths makes is suitable for a variety of shooting applications. Utilising a smaller OS unit and an optimised distribution of optical and electronic elements, the size of the lens barrel is able to be reduced in size by approximately 30%. This reduction in weight is also afforded in part through the use of TSC materials in the barrel construction. This material offers high durability and rigidity but with less bulk than metal components.
Macro Shooting Capabilities
This lens features a maximum magnification of 1:2.8 and a minimum focus distance of 22cm, giving a working distance of just 5.5cm when shooting at the 70mm focal length.
Optimised Lens Construction
Two FLD (F Low Dispersion) glass elements, one SLD (Super Low Dispersion) glass element, and three aspherical glass elements, including a double-sided aspherical lens, are integrated into the lens' construction to help improve overall image quality. The combination of these elements provides a reduction in both chromatic and axial chromatic aberrations throughout the focusing and zoom ranges. A Super Multi-Layer Coating is also applied to lens surfaces to reduce the appearance of lens flare and ghosting, which helps to maintain image contrast and colour fidelity when working in strong lighting conditions.
Hyper Sonic AF Motor
The HSM (Hyper Sonic Motor) provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications.
The OS (Optical Stabiliser) system is incorporated into the lens to provide a four-stop-equivalent reduction in the appearance of camera shake. This enables greater handheld shooting possibilities when working in low-lit situations, at longer focal lengths, and when working with macro subjects.
Compatible with Sigma's USB Dock and Sigma Optimisation Pro software for fine-tuning your lens' performance, updating its firmware, and better suiting it to your needs.
- A large maximum aperture of f/2.8-4 helps with low-light photography and also offers greater control over your focus plane for selective focus shooting.
- A brass bayonet mount provides reinforced durability at the connection point between the lens and your camera.
