Among its most important technical features are a maximum aperture of f/3.5-6.3, a minimum focus distance of 35 cm and a magnification ratio of 1:2.9. With Sigma's Hyper Sonic Motor (HSM) system, the autofocus is fast and quiet. And uniquely for this lens, it offers Optical Stabilization (OS) to help prevent blur.
Ideal for the traveling photographer or for those who need a single practical and versatile lens for every occasion. Thanks to its admirable ability to cover different focal lengths, it can easily switch from documenting landscapes to capturing details in extreme close-up without the need to change lenses.
