The Sigma 500mm f/4 DG OS HSM Sports is a hyper-telephoto prime lens for full-frame DSLR cameras, and APS-C sensor cameras with an effective increase in the focal length. Designed for the professional sports and wildlife shooter, the Sigma 500mm f/4 DG OS HSM Sports features a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas of the image, an Optical Stabilizer system that compensates for up to 4 stops of shutter speed with an accelerometer for improved vertical and horizontal panning, an Hyper Sonic Motor for fast and quiet autofocusing, manual override (MO) which is activated by rotating the focus ring while using autofocus.

Water and oil-repellent coating on the front element, a drop-in rear filter slot, a carbon fibre hood, and a dust and splash-proof construction. The Sigma 500mm F4 is available in Canon, Nikon and Sigma mounts, with the Nikon version featuring the new electromagnetic diaphragm.
