一般的摄影镜头,当光线通过镜头时,从第一组镜片进入,直接到达胶片。这类镜头如焦距达300mm-500mm甚至1000mm时镜头长度很长,重量也会增加数倍,使用起来会极不方便,而折反镜头利用光线折反得原理,使光线通过第一组镜片时,不是直接到达胶片,而是经过两次反射后才到达胶片。折反镜头最大限度地降低了镜头长度和重量,直径略大,降低了成本。 由于光学结构的特殊性,折返镜头不但体积小、重量轻,而且还没有恼人的色差现象,画质表现优良。不过出于对体积的妥协,折返式镜头只有一级光圈,即无法调整光圈的大小。这不但使得景深控制比较困难,而且对曝光也提出了较高的要求。当需要以特定曝光时间进行拍摄时,便只能利用减光镜来控制曝光了。
