What does the wide angle of the camera mean?

To say what telephoto and wide angle are, we must first understand the focal length. In fact, when people talk about the focal length of a digital camera, they are not talking about the actual focal length of the digital camera, but about the equivalent focal length, that is, the focal length relative to the traditional 135 camera. From the principle of photography, the smaller the focal length, the wider the field of vision, and the wider the range of scenery that the photo can accommodate; The larger the focal length, the narrower the field of view, which means that you can shoot distant objects.

The so-called wide-angle lens is a lens with short focal length and large viewing angle. Generally speaking, a lens with a focal length less than 35mm equivalent to a 135 camera can be regarded as a wide-angle camera, but on a digital camera, it is generally 28mm below 35mm, so in many cases, we are used to calling a digital camera with a focal length less than 28mm a wide-angle digital camera.

Wide-angle lens is mainly suitable for shooting larger scenes, such as architecture, scenery and other themes. When taking scenery, it can be used to take wider pictures, and when taking group photos, it can accommodate more people and so on.

At the same time, wide-angle lens can produce the effect of big prospect and small prospect. The distortion of the picture produced by wide-angle lens exaggerates the foreground object, highlights the foreground object more, and gives people a strong visual impact.

Generally, the wide-angle function of 28mm is enough for shooting.
