已經買了SIGMA 70-200mm F2.8 EX APO HSM DG OS 這支了 不會期待也
...(恕刪)
恭喜入手好鏡
無奈這體積跟重量讓我卻步
所以才想要這支s150 marco OS兼用長焦跟微距兩種用途
重量推估應該跟目前沒有OS這款不會相去太遠(750克~800克)
雖然也並不輕不過跟70-200 2.8系列相較之下只有一半重量左右

SIGMA APO MACRO 150mm F2.8 EX DG OS HSM
The Sigma Corporation is pleased to announce the new Sigma APO MACRO 150mm F2.8 EX DG OS HSM.
This is a large aperture medium telephoto macro lens which incorporates Sigma’s proprietary Optical Stabilizer system. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro. Three SLD (Special Low Dispersion) glass elements provide excellent correction of all types of aberrations and the Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. Equipped with Sigma’s own proprietary 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 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. It is also possible to use this lens with Sigma’s APO TELE CONVERTERS.
舊版的光學表現已經非常棒了, 沒想到新版的 MTF 曲線還要更好.
但還是要等上市後,看看其他網站的測試表現及大家使用的心得才準.
不過這支是值得期待的. 也希望它的對焦不會有什麼問題.
在ebay看到有人賣約 1100 美金.
