What is the difference between a single-lens reflex camera and a twin-lens reflex camera?

1. Different viewing methods

1. Single-lens reflex camera: A camera that uses a single lens, and the light shines on the reflector through the lens, and the view is captured through the reflection.

2. Twin-lens reflex camera: A camera that uses twin lenses, and the light shines on the reflector through the lens, and the view is taken through the reflection.

2. Different characteristics

1. Single-lens reflex camera: The photographic exposure light path and the viewing light path use one lens, unlike the viewing light path of a rangefinder camera or a twin-lens reflex camera. There are independent lenses.

2. Dual-lens reflex camera: It adopts a dual-lens structure. The two lenses are arranged up and down and fixed on the lens holder. The upper lens is used for viewing and the lower lens is used for shooting.

3. Different operation methods

1. Single-lens reflex camera: The reflector falls when taking pictures, reflecting the light from the lens to the pentaprism and then to the viewfinder window; when shooting, the mirror Lift it up quickly, and the light can shine on the film or photosensitive element CMOS or CCD.

2. Twin-lens reflex camera: When observing the subject, you must put up the hood and look down at the camera. Additionally, a magnifying glass in the shield facilitates chest-level viewing of the focusing screen.
