单镜头反光相机特点之一 ,就在于可配接不同功能的镜头完成不同的拍摄任务。而镜头与机身的配接是通过接口来实现的 ,接口问题就特别显眼。在单反机发展的初期 ,由于市场自由经济的无序性 ,“跑马圈地”的排他心理 ,“确信自己的接口设计最好”的自信心理 ,接口技术中的专利障 One of the characteristics of single-lens reflex cameras, is that it can be equipped with different functions of the lens to complete different shooting tasks. The matching lens and the fuselage is achieved through the interface, the interface problem is particularly conspicuous.
