感兴趣的是新180微，因为很多人反映微距头在SD1M上表现很好，因此相当值得期待，一些资料：

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 Stabilizer function and 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 color aberrations. This lens incorporates
Sigma's floating inner focusing system. This minimizes aberrations which 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. 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.

来个特写：

180微.看上去很好.

新50-150和新180微都让人眼馋啊

新50-150的重量跟大小竹炮相仿，让人浮想联翩啊，我不禁想起号称“魔镜”的奥巴 35-100/F2，画幅更小，但是重量同样惊人
