Professional cameras are also called SLR cameras, and complete cameras should be called SLR cameras. The unique design of the mirror and prism of this camera enables the photographer to directly observe the image passing through the lens from the viewfinder. After the light reaches the reflector through the lens of the camera, it is refracted to the focusing screen above to form an image. Through the eyepiece and pentaprism, the photographer can see the scenery outside in the observation window. When shooting, press the shutter button, the reflector will pop up and the shutter curtain in front will open at the same time. The light image passing through the lens will be projected to the photosensitive part. The traditional camera is film, and the digital camera is CCD or CMOS to make it sensitive. Then, the reflector will immediately return to its original state, and the image can be seen again in the observation window. The lens of a professional camera can be completely removed and replaced with another lens, thus obtaining different shooting effects. Professional cameras have a wide range of lenses, with prices ranging from thousands to tens of thousands, and many lenses are even more expensive than the fuselage.
