　　The role of fisheye lens,the function of fisheye lens is that the viewing angle range is large,and the viewing angle can generally reach 220°or 230°,which creates conditions for shooting a wide range of scenes at close range;The strong perspective effect,emphasizing the contrast between the large and small of the subject,makes the captured picture have a shocking appeal;the fisheye lens has a relatively long depth of field,which is conducive to expressing the long depth of field effect of the photo.

　　There are two types of fisheye lens imaging,one is like other lenses,the imaging fills the screen;the other is circular.No matter what kind of imaging,the image captured by the fisheye lens is quite deformed and has a strong sense of perspective convergence.So it is often used as a special effect lens,an arm stretched towards the fisheye lens will appear twice as long as it was originally.For example,Wong Kar Wai's"Fallen Angels"(1995)used a lot of fisheye lenses.

　　The fisheye lens has a large field of view,so it is widely used in scene monitoring,satellite positioning,robot navigation,micro intelligent system and engineering measurement and other fields.Because the fisheye lens can achieve full airspace inclusion and full time domain real-time information acquisition,especially in line with the needs of modern warfare for information acquisition technology,which is unmatched by other photoelectric detection methods,so the fisheye lens is widely used in national defense and military areas have also been widely used.
