The Sigma APO Macro 180mm F2.8 EX APO DG OS HSM incorporates a magnification ratio of 1:1 and a large maximum aperture of F2.8 and benefits from Sigma’s original Optical Stabilizer function.
The wide F2.8 aperture allows faster shutter speeds for narrow depth of field, enabling photographers to emphasize 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 minimizes 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 Stabilizer) 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. A rounded 9 blade diaphragm creates 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.
