Lens Description

The Sigma C 17-70mm F/2.8-4 DC Macro HSM is a wide to short telephoto zoom designed for cameras with a APS-C (1.5X) sensor. This bright variable-aperture zoom covers a 17 to 70mm focal-range. It provides the same field of view as a 25.5-105mm lens on a Full-Frame camera.

This 4X zoom lens focuses down to 22cm from the imaging plane, capturing subject with a maximum 0.24X magnification. The lens offers a Quick-Shift AF system which lets the user simply rotate the focus-ring to focus manually. A Super-Sonic motor inside the lens delivers very fast and relatively quiet AF.

The lens weighs 465g.

This version of the lens has a Sony A mount. It directly attaches and is fully compatible with all Sony A mount cameras with APS-C (1.5X) sensors. Sigma also makes this lens for Pentax K mount.
