The Sigma lens Sigma 17-70mm F/2.8-4 DC Macro OS HSM C is a stabilized standard zoom (for Sigma, Canon and Nikon mounts) and completely customizable for DSLR (Optimized for APS-C sensors) .
Compatible with the new Sigma’s USB Dock and Sigma Optimization Pro software for fine-tuning the lens’ performance and updating its firmware
This standard zoom Sigma 17-70mm F/2.8-4 DC Macro OS HSM C covers the most common focal lengths and is therefore suitable for landscape, reportage, portraits and everyday use. Its minimum focusing distance of 22cm, allows him to do macro photography with a magnification ratio of 1: 2.9.
The framing and composition can be adjusted with the zoom ring, which can sometimes be more practical for macro photography than with a fixed focal length (prime lens). It’s all about habit.
I haven’t used it for in macro photography yet, as I already have a macro lens for that. But it is worth to be tested.
Very bright thanks to a maximum aperture of F2.8, the Sigma lens 17-70mm F/2.8-4 DC Macro OS HSM C is still very compact. A little too much perhaps, because sometimes I find the focusing ring very close, and if you have large hands, you may mistake it with the zoom one.

Sigma 17-70 2.8-4 DC Macro OS HSM C The newest version, PhotoRec Toby:
The new materials used to build the Sigma lens 17-70mm F/2.8-4 DC Macro OS HSM C, allow it to be robust (body designed using Thermally Stable Composite (TSC) materials) and have great optical performance (Two FLD (F Low Dispersion) glass elements, one SLD (Super Low Dispersion) glass element).
A Super Multi-Layer Coating that also reduces “flare”, durability and rigidity, solid construction, all for a good price / quality ratio.
