In terms of wedding photography, many people use SLR as a camera at present, because SLR cameras have several characteristics: First, because the sensor of SLR cameras is large, it is easy to form a shallow depth of field, which can highlight the blur of the background of the subject when shooting. Second, a rich lens group. Both Canon and Nikon have rich lens groups. Now Canon EF lenses have more than 60 models, ranging from 8mm ultra-wide angle to 800mm ultra-wide focal length, macro lens, fisheye lens and shift lens, which can also achieve special effects. Third, high sensitivity. In the dark environment, SLR cameras can take pictures with pure pictures and low noise at night by improving the sensitivity. It is difficult for traditional cameras to achieve good results in the dark or in a room with poor light. Fourth, it is simple and convenient. Compared with the traditional video camera, SLR camera is easier to carry, and because of its small size and easier operation, it can shoot some translation and moving lenses more easily. Fifth, the price is cheaper. The lens can be changed. Few cameras with the same price can change lenses. This is the main reason. Sixth, the picture is more delicate, saving the time of post-processing.

But whether it is better to use a SLR or a camera depends on the individual. Novices don't need SLR, after all, SLR is not as convenient as camera in operation, especially in automatic state. SLR is suitable for people who have some knowledge of photography.

In wedding photography, some people use SLR cameras, but many people use cameras, but you just don't see them. It is still easier to shoot with a large sensor camera than with a SLR, especially with a zoom lens.
