What's the difference between SLR cameras and ordinary cameras?

The difference between a normal camera and a SLR camera: 1. The lens of SLR cameras can be replaced according to different shooting needs, while the lens of ordinary cameras cannot be replaced. There are many lens configurations of SLR cameras that can be upgraded, but ordinary cameras do not have this function. Ordinary cameras cannot be upgraded, and there are fewer accessories.

2. There is no delay in focusing the SLR camera, and the capture effect is very good. Ordinary cameras have no focusing function, which will delay shooting and sometimes lead to bad pictures.

3. The CPU used in SLR cameras is relatively large, which is several times larger than that of ordinary cameras. SLR cameras have more lenses and better picture quality, while ordinary cameras have only one lens and the picture quality is also average.

4. SLR cameras can adjust the mode according to the site and their own needs, while ordinary cameras can only use one mode.

5, SLR camera reflective technology is better, you can use more functions. Ordinary cameras have few functions. SLR cameras use mirrors and pentagonal mirrors, while ordinary cameras only use ordinary flat mirrors.

6. The imaging size of ordinary cameras and SLR cameras is different, and the imaging size of ordinary cameras will be smaller than that of SLR cameras. Compared with ordinary cameras, the pixels of SLR cameras are much higher, so the biggest difference between SLR cameras and ordinary cameras is pixels and high intensity.

7. The price of SLR cameras is different from that of ordinary cameras. Ordinary cameras only cost about 1000 yuan, and SLR cameras cost more than 3,000 yuan. SLR cameras are much more expensive than ordinary cameras.

Zoom multiple: the zoom multiple of a camera shows the shooting adaptability of this camera to some extent. The wider the wide-angle end of the lens focal length (the smaller the number), the wider the scene that can be shot; The longer the telephoto end (the larger the number), the farther the scene can be shot. At present, the wide-angle difference of digital cameras is very small, so the larger the zoom factor, the farther the scene can be taken.

Now there are some large zoom cameras, the zoom factor can reach more than 20 times, which can not only shoot the big scene in front of us, but also shoot distant objects. In sports competitions, concerts and other occasions that require long-distance shooting, large zoom cameras are quite useful, while ordinary digital cameras are difficult to shoot so far.

For zoom lenses, the larger the zoom multiple, the more complicated the lens structure and the more lenses are needed. Whether it is design or production, it will be more difficult. In addition, due to the increase of lenses, it often has a huge impact on image quality. A large zoom factor basically sacrifices the image quality for the convenience of shooting.

If you often need to shoot from a long distance and take care of your daily close-up shooting, then you can consider choosing a large zoom camera. At present, the zoom factor of large zoom cameras ranges from 10 to 20, so the smaller the zoom factor, the better.

SLR cameras (SLR cameras) are also called SLR cameras. Refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.

The so-called "single lens" means that the photographic exposure light path and the framing light path share a lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens. "Reflection" means that a plane mirror in the camera separates the two light paths: when the mirror falls during framing, it reflects the light of the lens to the pentaprism and then to the framing window; When shooting, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.
