Sigma Imaging UK Ltd is pleased to announce that the new Sigma APO Macro 180mm F2.8 EX DG OS HSM will have a Suggested Retail Price of 1499.99. This new lens will be available in the UK on 27th July for Canon fit. Sigma and Nikon fittings will follow.

This is the worlds first 180mm macro lens incorporating a magnification ratio of 11 and a large maximum aperture of F2.8. It benefits from Sigmas original Optical Stabiliser function and the wide F2.8 aperture allows faster shutter speeds for narrow depth of field, enabling photographers to emphasise the subject. Three FLD F Low Dispersion glass elements provide excellent correction for colour aberrations.

This lens incorporates Sigmas floating inner focusing system which minimises aberrations that occur as shooting distances change and enables stable rendering of the image from infinity to 11 magnification. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even at the maximum aperture.


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
