军用装备？ 适马APO 200-500 F2.8巨炮风采

 

在美国的PMA 08展会上，适马刚刚发布了世界上第一支200－500mm F2.8镜头。这支镜头的参数确实惊人，在500mm端全开F2.8的光圈应该是一种神奇的体验。还是让我们看看这支镜头的照片吧，看到绿色的镜身，很多人会误以为这是一支军用镜头，但它确实是一支民用镜头，并将配备适马、佳能和尼康卡口。

 

 

Sigma 200-500 f/2.8 EX DG

 

这支镜头净重16公斤，自动对焦需要有一个单独的系统控制，并需要BP-21锂离子电池提供动力。镜头结构为13组17片，并运用了多片超低色散镜片，有效提高了图像质量。遮光罩与镜头设计在一起，滤镜尺寸为72mm，当然它只能使用后端滤镜。

下面我们来看一看这款拥有“恐怖”身材的镜头到底是什么样子的。
