What does a super wide-angle lens mean?
A super wide-angle lens is a photographic lens with a focal length shorter than the standard lens, a viewing angle larger than the standard lens, a distance longer than the fisheye lens, and a viewing angle smaller than the fisheye lens.
take Nikon Nikkor Z 14-3mm f/4 S as an example, which means that a lens with a particularly wide viewing angle needs to reach 8~11 degrees before it is called a super wide-angle lens. This lens is characterized by a particularly wide line of sight and a particularly deep framing. It is generally used for shooting with the scenery or ordinary scenery, and is more suitable for shooting large scenes, such as some tall buildings or landscape themes.
characteristics of super wide-angle lens
1. When shooting with the maximum aperture, obvious "dark angle" is easy to appear. These reefs gradually change from the deepest black around to the middle, which is the "lomo" effect in many retouching app filters of mobile phones, which can better guide the line of sight and achieve the role of highlighting the main body. If you want to get rid of this dark corner, the aperture will be as small as possible in the early shooting, and the dark corner will be reduced.
2. The depth of field is very large. Even if you shoot with the largest aperture, the scenes from near to far in the scene are basically clear.
3. The perspective is serious, and the distortion effect of "near big and far small" is conducive to creating an exaggerated picture effect. Try to avoid straight lines in the picture when shooting scenery photos in the early stage. If you are shooting buildings, you can't avoid lines anyway, and you can also process them in ps later.
