摘　　要：变形宽银幕镜头设计之初是为了充分利用胶片的面积,从而拍摄视角更广的画面。由于其内部特殊的成像结构,使得在使用变形宽银幕镜头拍摄时呈现出独特的画面效果,与普通成像镜头相比有鲜明的区别。本文从变形宽银幕镜头发展历史脉络阐述其成像原理、成像特性以及光学缺陷等方面,结合短片《林月珍女士》拍摄中使用变形宽银幕镜头的实地感受,分享创作经历。At the very beginning,anamorphic lens was designed to make the most of film area in order to acquire frames with wider angle.Due to its special internal imaging structure,filming with anamorphic lens would show a unique imaging effect which is quite different from the ordinary lens.This paper uses short film,Truthless as a sample to analyse history of anamorphic lens and its imaging principle,characteristics and optical flaws.Both practical experience of using anamorphic lens and creative thoughts during filming Truthless are also what this study would share.
