Shooting effect of wide-angle lens
Wide-angle lens Wide-angle lens is widely used to shoot large-scale landscape photography. Can increase the sense of spatial depth of the photo picture; The depth of field is long, which can ensure that the scene before and after the subject can be clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool cameras) use ordinary wide-angle lenses of 38-35 mm; The lens covers a large area and shoots a wide range of scenery; The scene shot at the same shooting distance is smaller than the scene image shot with standard lens in the picture; The defects of perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is.
For most popular digital cameras on the market, the wide-angle focal length is generally between 35 and 38mm. The real wide-angle digital camera is actually a product with a lens focal length covering a wide angle of 28mm. Because the wide-angle field of view of 28 mm is wider than that of 35mm and 38 mm commonly used in digital cameras, the wide-angle field of view of 28 mm is 76 degrees, while that of 35mm is only 62 degrees, so it can produce very unique visual effects and accommodate a wider scene. This is also the reason why consumers are more optimistic about 28mm wide-angle digital cameras. The biggest feature of wide angle is that it can shoot a wide range, with exaggerated sense of distance and wide focus range. When using wide angle, you can enlarge the object in front of you and narrow the object in the distance, and the surrounding images are easily distorted. Wide-angle can also adjust any point in the image to the most appropriate focal length to make the picture clearer, which can also be called complete autofocus.
