Versatile APS-C zoom for everyday and close-up work

The Sigma 17-70mm F2.8-4 Contemporary DC Macro OS HSM covers a wide 17-70mm focal range with a variable F2.8-4 aperture. It is built for APS-C format DSLRs and includes optical stabilisation for handheld shooting. The lens accepts 72mm filters and uses a micro-type ultrasonic motor for quiet focusing. Its thermally stable composite construction keeps weight down while maintaining durability.

Consistent close-focus performance across the zoom

Minimum focusing distance stays at 22cm (8.6in) from wide to telephoto, delivering a maximum magnification ratio of 1:2.9 for detailed macro work. Optical stabilisation helps maintain sharpness at slower shutter speeds when working close to subjects. The seven-blade diaphragm produces smooth background rendition throughout the aperture range of F2.8-4 to F22-22.

1:2.9 macro magnification at 70mm telephoto

This single specification defines the lens's close-up capability. Buyers needing true 1:1 life-size reproduction will need a dedicated macro optic instead. The 1:2.9 ratio suits product details, flowers and textures but does not fill the frame with tiny subjects at actual size.
