Having a viewing angle of 180ï¿1/2, these lenses can provided a very surreal image. Can be divided into diagonal types which provide a frame-filling picture; or circular lenses which project a round image on the frame.
An extreme-wide-angle lens in which all lines appear to curve around the center.
a wide angle lens that captures the scene exactly as it appears, thereby incorporating curves which the human eye does not perceive because the focal length of the human eye is approximately 50mm. Fisheye lens images tend to cause all straight lines to appear curved. See also rectilinear lens. You can use such lenses and use a program like DeFish to make it rectilinear and therefore usable in a simple stitching program like PhotoStitch (Canon.com)
a camera lens having a wider than normal angle of view (and usually a short focal length); produces an image that is foreshortened in the center and increasingly distorted in the periphery
a wide-angle lens that projects deliberately distorted images
Pictures taken with fisheye lenses are distorted and have practically infinite depth of field. These lenses have an angle of view exceeding 100 degrees and up to 180 degrees.
A very short focal length lens with a field of view of about 180 degrees. Be careful using this type of lens you can easily get your toes in the shot! Yes, your toes these lenses truly provide a 180 degree field of view. This lens may require you to lock up your shutter because they actually extend into the camera body so far that your mirror has no room to travel up normally. Be sure your camera has a mirror lock up button.
Ultra-wide angle lens giving 180 angle of view for the user
A fisheye lens is an extreme wide-angled lens which creates barrel distortion.
extreme wide-angle lens which produces a circular image.
a lens with an extremely wide angle of view, as much as 180 degrees, and considerable barrel distortion (straight lines at the edges of a scene appear to curve around the center of the image)
An extreme wide angle lens. Most fisheye lenses cover a 180 degree angle of view, popular focal lengths include 6, 8 and 14mm. The 6mm and 8mm lenses produce a circular image on the film. (not full frame)
Super wide angle lens. Angle of view can approach 180 degrees. Nearly infinite depth-of-field.
AAn extreme wide-angle lens. Most fisheye lenses cover over 180 degree angle of view and produce circle-shaped pictures on film.
extreme wide-angle lens with an angle of view exceeding 100° and sometimes in excess of 180°. Depth of field is practically infinite and focusing is not required.
In photography, a fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image. Originally developed for use in astronomy and called "whole-sky lenses", fisheye lenses quickly became popular in general photography for their unique, distorted appearance. They are often used by photographers shooting broad landscapes to suggest the curve of the Earth.
