It looks impressive on paper. With a good focal length choice with the resulting working distance in macro and close-up shooting, plus it will probably be quite at home with more general photography.

Here are the official details:

APO Macro 180mm F2.8 EX APO DG OS HSM

Telephoto macro lens with a fast aperture and Optical Stabilisation.

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 world’s first 180mm macro lens incorporating a magnification ratio of 1:1 and a large maximum aperture of F2.8. It benefits from Sigma’s 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 Sigma’s floating inner focusing system which minimises aberrations that occur as shooting distances change and enables stable rendering of the image from infinity to 1:1 magnification. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even at the maximum aperture.

Equipped with Sigma’s 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 1:1 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 Sigma’s optional Tele Converter’s allows photographers to shoot with an even greater working distance or with a magnification ratio larger than 1:1.

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.
