1, structure
Double reflection camera: Reflective viewfinder with two lenses, one directly above the other.
SLR camera: It is a single-lens reflective viewfinder.
2. Features
Double-reflex camera: Compared with SLR camera, double-reflex camera has an extra lens for framing, and the reflector is fixed, so it does not affect framing when photos are exposed.
SLR camera: The light passes through the lens and is reflected by the reflector to the frosted viewfinder screen, but the viewfinder screen is covered by the reflector, and no image can be seen during exposure.
3. Function
Double-reflex camera: the lower lens is responsible for transferring the image to the film, and the image from the upper lens is only used for framing and focusing.
SLR camera: The photographic exposure light path and the framing light path * * * use one lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens.
When using a double-reflex camera, you usually hold it waist-high and look down at the frosted glass for framing. The image seen on the ground glass is also 6 × 6 cm; And the up and down direction of the image is correct, but the left and right direction is opposite.
