This is the world’s first 180mm macro lens incorporating a magnification ratio of 1:1 and a large maximum aperture of F2.8.Extra Description
Focusing distance of 47cm/18.5-Inch Equipped with Sigma's own propriety OS (Optical Stabilizer) system, this lens offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, enabling handheld close-up photography. This lens incorporates Sigma's floating inner focusing system. This minimizes aberrations which occur as shooting distances change, and enables stable rendering of the image from infinity to 1:1 magnification.
