Sigma Contemporary 18-50mm f/2.8 DC DN
A constant f/2.8 aperture across the 18-50mm zoom range is packed into a weather-sealed body weighing just 290g, making it exceptionally portable for APS-C mirrorless systems. Its stepping motor delivers fast, quiet autofocus and the 4.8-inch minimum focus distance enables 1:2.8 magnification macro-style close-ups. This lens is best for travel photographers and hybrid shooters who need a lightweight, versatile standard zoom without sacrificing low-light capability.

竞品对比
放在当前市场里,Tamron 28-75mm f/2.8 G2在光圈和锐度上全面领先,Sigma 10-18mm f/2.8则用更广的视角和恒定光圈抢走了风光和视频用户。Panasonic Leica 12-60mm和Canon RF 28-70mm f/2.8 IS STM也分别在防抖和人像焦段上给出了更诱人的方案。这只镜头只能靠价格和重量来守位。

最终评价
降价之后它找回了些存在感,但整体评分从90滑到77,说明竞品进步更快。Tamron和Sigma的新镜头在光学素质和做工上压得很凶,这只镜头现在更像是一个够用且便宜的选择,而非当初那个让人惊喜的选手。
