A fisheye lens is an ultra wide-angle lens that produces strong visual distortion proposed to form a wide panoramic or hemispherical image. Fisheye lenses accomplish exceptionally wide angles of view by forgoing creating images with straight lines of perspective opting instead for a special mapping， which gives images a characteristic convex non-rectilinear appearance. Macro lens is used for extreme close-up photography， usually of very small subjects， in which the size of the subject in the photograph is greater than life. By some definitions， a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. In photography and cinematography， a wide-angle lens refers to a lens whose focal length is considerably smaller than the focal length of a normal lens. This type of lens allows more of the scene to be included in the photograph， which is useful in architectural， interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.
