The films made by SLR cameras, especially Canon SLR cameras, especially in RAW format, completely retain the original data of the films, so they give the creators a lot of space later. So Canon SLR is very professional.
The more professional the equipment, the less functions it has. It all depends on the photographer's own skills. If you take photos with a SLR when your knowledge of photography is limited, you might as well take photos with a card machine or even a mobile phone. Even many times, the SLR is not good, such as not focusing, the shutter is unresponsive, and the photo is blurred.

SLR digital camera refers to a single-lens reflex digital camera, that is, DSLR(Digital Single Lens Reflex).
In this system, after the light reaches the mirror through the lens, it is refracted to the focusing screen above to form an image. Through the eyepiece and pentaprism, we can see the scenery outside in the observation window. In contrast, ordinary digital cameras can only see the captured images through the LCD screen or electronic viewfinder (EVF). Obviously, the directly seen image is more conducive to shooting than the processed image.
When shooting in DSLR, press the shutter button, the reflector will pop up, and the shutter curtain in front of the photosensitive element (CCD or CMOS) will be opened at the same time, and the light passing through the lens will be projected onto the photosensitive original, and then the rear reflector will be restored immediately, and the image can be seen in the viewfinder. This structure of the single-lens reflex camera ensures that it is shot through the lens, so that the image seen in the viewfinder is always consistent with the image on the film, and its framing range is basically consistent with the actual shooting range, which is very conducive to intuitive framing and composition.
In addition, 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.
