- ViewFinder :-> 取景器
- reflex mirror :-> 反射镜
- Pentaprism :-> 五棱镜，五棱镜通过两次反射光线，将其从垂直方向转换为水平方向，直接传递到取景器
- Shutter :-> 快门
Difference Between DSLRs and Mirrorless Cameras
- 两种相关最大区别 #card
无反光镜
he mirror and prism in a DSLR directs light coming from a lens, and allows you to view your scene through an optical viewfinder. Since mirrorless cameras do not have a mirror and prism mechanism, they do not use an optical viewfinder.
单反相机中的反光镜和五棱镜会将镜头进来的光线导向取景器，让你可以通过光学取景器观察场景。由于无反相机没有反光镜和五棱镜机制，因此它们不使用光学取景器。
Instead, mirrorless cameras display a preview of the scene you are photographing by using the light hitting the digital sensor directly, and thus instead of an optical viewfinder as in DSLRs, mirrorless cameras have electronic viewfinders (EVF).
相反，无反相机通过直接使用照射到数码传感器上的光线来显示拍摄场景的预览，因此无反相机使用电子取景器（EVF），而不是单反相机的光学取景器。
