Do SLR cameras belong to digital cameras?

SLR cameras belong to digital cameras. SLR is a more advanced camera than card DC.

Single lens reflection. The camera using this technology has only one lens, which is responsible for photography and framing. This can basically solve the problem of poor photo quality caused by parallax.

Moreover, when a SLR camera is used to view a scene, the light emitted by the object is focused by the lens, reflected by the inclined reflector to the focusing screen for imaging, and then reflected by the "roof prism" raised at the top. Photographers can observe the scene through the viewfinder eyepiece, and it is the same image as the scene, which is convenient for framing and focusing.

When shooting, the mirror will bounce up immediately, the lens aperture will automatically shrink to a predetermined value, and the shutter will open to make the film sensitive; After exposure, the shutter is closed and the aperture of the mirror and lens is reset at the same time. This is the SLR technology in cameras. After adopting this technology, digital cameras become professional digital SLR cameras.

Extended data

main feature

A major feature of SLR digital cameras is that they can change lenses of different specifications, which is an inherent advantage of SLR cameras and incomparable to ordinary digital cameras.

In addition, SLR digital cameras are located in the high-end products of digital cameras, so in terms of the area of photosensitive elements (CCD or CMOS) related to the photographic quality of digital cameras, the area of SLR digital cameras is much larger than that of ordinary digital cameras, which makes the photosensitive area of each pixel of SLR digital cameras much larger than that of ordinary digital cameras, so each pixel can show more detailed brightness and color range, which makes the photographic quality of SLR digital cameras significantly higher than that of ordinary digital cameras.
