Luminous macro telephoto lens for a full-size image sensor. Also suitable for APS-C sensor. With Sigma's original on-lens image stabilizer (OS -Optical Stabilizer). The lens' three SLD (Special Low Dispersion) lens elements, plus multiple lens diaphragms, improve image sharpness by eliminating excess light dispersion.

Longer close focusing distance for easier macro photography, for example when shooting insects. Suitable for all telephoto photography. Built-in floating focusing system that moves the two groups of lenses inside the lens, reducing diffraction and distortion, enabling very high quality optical image quality from infinity to 1:1 macro photography.
