What do you mean by SLR and camera's double reaction?
Single-lens camera, reflective framing (referred to as SLR) is characterized by using the same lens for framing and photo imaging, thus achieving what you see is what you get.
Dual-lens camera, reflective framing, characterized by using one lens for framing and the other lens for film imaging, is quite primitive camera structure, characterized by the deviation between the shooting content and the viewfinder.
SLR is relatively low in cost, simple and stable in structure, and will become the development direction of cameras in the future.
