1、Higher Quality: Can increase the spatial depth of the photographic picture, and add the artistic impact and image quality. 2、Clear Picture: Longer depth of field can ensure that the front and rear scenes of the subject be clearly appeared on the screen. 3、Wider Scene: The lens can cover a large area and shoots a wide range of scenery in a picture. 4、Less Defects: It is easy for perspective distortion and image distortion to appear in the picture. The shorter the focal length of the lens and the closer the shot distance, the more significant this defect becomes. 5、More Scenery: The image taken by the wide‑angle lens in the same shooting distance is smaller than the image taken by the scene taken by the standard lens.
