Extended data:
Comparison between dual-reflex camera and SLR camera;
Dual-lens and single-lens reflex have different film specifications. 120 film is generally used for double-lens reflection, and 135 film is generally used for single-lens reflection. The previous 120 tablets were worse than 135 tablets, but the later professional 120 tablets were much better.
Double reflex is a dual-lens reflex camera, named after having a camera and a viewfinder lens respectively. Because the viewfinder and camera are two optical paths, there is parallax, so it is more common to use 120 film. SLR is a single-lens reflex camera, which uses the same lens for framing and photography, and has no parallax. 135/ 120/ all digital cameras have this structure.
