The versatile Sigma 17-70mm f/2.8-4 DC Macro OS HSM Zoom Lens is a standard macro zoom for digital SLR cameras with a Sigma lens mount. The lens is designed for cameras with APS size chips, and covers the most frequently used focal lengths. The maximum aperture of f/2.8 is fast enough for use under a wide variety of lighting conditions. The OS anti shake feature offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.
Hyper Sonic Motor (HSM) ensures quiet and high speed AF as well as full-time manual focus. For shooting macro this lens has a close focusing distance of 8.7" (22cm) and a magnification ratio of 1:2.7 (approx. 1/2 life-size) making it ideal for getting in tight during nature, product, still life, medical and technical shooting sessions. This lens is flexible enough to also deliver excellent image captures at medium telephoto distances for portraits, nature and landscapes.
