What kinds of digital cameras are there?

Digital cameras as a whole can be divided into three categories: SLR cameras, paraxial cameras (professional here, not paraxial cameras) and consumer cameras. The first two are professional or quasi-professional cameras, which are expensive and difficult to control, and are not recommended for novices.

SLR camera is a kind of digital camera that uses the new technology of single lens reflection, which is referred to as SLR for short. This technology is to install a pentaprism above the ground glass in the camera and put it in front of the film plane at an angle of 45. This prism reflects the real image light many times to change the optical path and send the image to the eyepiece, so that the image seen in the observation window is always the same as that on the film, and the observation range is basically the same as the actual shooting range. The unique design of this prism enables the photographer to directly observe the image passing through the lens from the viewfinder.

Paraxial camera, also known as paraxial camera, is named "paraxial camera" because its viewing optical axis is located next to the optical axis of the photographic lens and parallel to each other. In the whole process of camera technology development, this kind of camera is the most diverse and structurally different, so it has the most cultural characteristics. From the outstanding Leica products, to the famous Lulai double reflex, and then to the world's first paraxial digital camera Epson R-D 1, they are all members of paraxial cameras, so paraxial cameras are undoubtedly an important part of camera development.

Consumer camera, the so-called consumer camera, usually refers to our common brand camera in the market, and its function is mainly used for our daily shooting as a souvenir, tourism shooting or amateur shooting learning. Its structure, function and cost are mainly oriented to ordinary consumers. For example, common card cameras, some brands of individuals use single-lens reflex cameras with less than 20 million pixels, and so on.

The main difference between it and professional cameras lies in the difference in the purpose of use and the crowd. Professional cameras are aimed at professional photographers and are often used to shoot advertisements, magazines or professional landscapes. The construction cost of these cameras is much higher than that of ordinary consumer cameras.

Beginners are advised to practice their skills with consumer cameras first, and then choose professional models after their skills are improved.
