What are the different effects of different lenses in landscape photography?

1, the angle of view obtained through the lens is different. Generally speaking, the shorter the focal length, the wider the viewing angle, which is called a wide-angle lens; The longer the focal length, the narrower the viewing angle, such as telephoto lens, which is used to shoot animals and insects, and the subject occupies a large part of the picture;

2. The depth of field obtained by different focal lengths is different. The longer the focal length, the smaller the depth of field. The shorter the focal length, the greater the depth of field;

3. Visual experience: Due to different perspectives, the film shot with wide-angle lens has more visual impact and looks deeper, which is actually the reason for the large depth of field, so the architecture and scenery are very shocking; The medium telephoto lens has a feeling of compressing the scene before and after, which is beneficial to blur the background and highlight the main body, making it look flatter. In fact, it is also the reason for the small depth of field, which is suitable for shooting flowers and birds and macro.
