Sigma MACRO 105mm F2.8 EX DG OS HSM เลนส์มาโครใหม่จากซิกม่า
ซิกม่าเปิดตัวเลนส์มาโครตัวใหม่ เพิ่มชิ้นเลนส์ SLD (Special Low Dispersion) เพิ่มระบบกันสั่นด้วย OS (Optical image Stabilization) และสามารถโฟกัสได้เร็วและเงียบด้วย HSM ( Hypersonic Motor )
The Super Multi-Layer Coating reduces flare and ghosting, providing high contrast images.
It is also possible to use this lens with Sigma’s optional APO Tele Converters. Sigma’s own proprietary OS (Optical Stabiliser) function helps with handheld close-up photography and the HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability.
This lens features a splash resistant design for use in harsh conditions and a rounded 9 blade diaphragm creating a smooth blur to the out of focus areas of the image.
