working principle
In the SLR digital camera operating system, the light through the lens to reach the mirror, the refraction to the top of the focusing screen and form an image, through the eyepiece and pentaprism, we can see the outside scene in the viewing window. In contrast, the general digital camera can only be seen through the LCD screen or electronic viewfinder (EVF) to shoot the image. It is clear that the image you see directly is better than the image you see.
In the DSLR shooting, when you press the shutter button, the mirror will bounce up, the sensor (CCD or CMOS) in front of the shutter curtain will open at the same time, through the lens of the light will be projected to the original photosensitive light, and then The mirror will immediately restore the status quo, the viewing window can see the image again. This configuration of a single-lens reflex camera confirms that it is completely shot through the lens focus, it can make the viewing window to see the image and film forever, its viewfinder and the actual range of shooting is basically the same , Is very conducive to intuitive framing.
main feature
SLR digital camera is a great feature that can exchange different specifications of the lens, which is the inherent advantages of SLR cameras, digital cameras can not be compared to ordinary.
In addition, now SLR digital cameras are located in the digital camera in the high-end products, so the relationship between digital camera photographic quality sensor (CCD or CMOS) area, SLR digital area is much larger than ordinary digital camera, which makes SLR digital The camera's pixel area of each pixel is much larger than the ordinary digital camera, so each pixel will be able to show more detailed brightness and color range, so that SLR digital camera photography quality was significantly higher than ordinary digital camera.
