Equipped with Sigmas own propriety OS Optical Stabiliser system, this lens offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, enabling handheld close-up photography. The incorporation of HSM Hyper Sonic Motor ensures quiet and high speed autofocus as well as full-time manual focus capability.
This lens has a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image. At 11 magnification, this lens has a focusing distance of 47cm/18.5in which is a greater working distance than shorter focal length macro lenses. This is advantageous when taking pictures of highly sensitive subjects such as butterflies and insects.
Attaching Sigmas optional Tele Converters allows photographers to shoot with an even greater working distance or with a magnification ratio larger than 11.
Supplied with fitted case, bayonet type hood LH927-01, hood adapter HA927-01 and tripod socket TS-21
The effectiveness of the OS system will gradually decrease as the shooting distance becomes shorter.THE SPECIFICATIONS
