摘要
本文阐述了传统单反照相机、数码单反照相机和单镜头电子取景数码照相机的结构、特性、工作原理和发展历程,对比了其各自的功能和性价比,并指出了:由于单镜头电子取景数码照相机在拍摄时记录下的景物与取景器上观察的景物完全是相同的,不存在任何时间差,而且相机结构相对较为紧凑、轻便,性价比较高,因此有可能取代数码单反照相机成为今后高档数码照相机的发展方向。
This paper presents an elucidation of the structure,characteristics,working mechanism and development history of traditional single lens reflex cameras SLR,digital single lens reflex cameras DSLR and digital single lens electronic view finder cameras DSLE, and a comparison of their functions and quality to price ratio.Owing to the fact that the scene taken by the DSLE cameras is identical to that seen on the view finder without any time difference and DSLE cameras are more compact and lighter,offering a higher quality to price ratio,it is concluded that this type of cameras will replace DSLR cameras and become the future development trend of high-end digital cameras.
