Is a 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.

Fisheye Lenses
The situation is rather more complex for fisheye lenses because there is no such thing as a "Fisheye" equation.
Add a fisheye lens to your optical arsenal. Sure, it can sometimes produce a corny, funhouse- mirror-like distortion.

Interestingly, a fisheye lens opens up possibilities for the shy street shooters among you. With a lens this wide, you can aim far away from your subjects, while still including them. The distortions can even enhance the feeling of the picture.
GLOSSARY: Full-Frame Fisheye Lens
Also know as a diagonal fisheye lens, a full-frame fisheye lens typically has a diagonal angle of view (the angle between areas that appear in diagonally opposite corners of the image) of 180 degrees.

Ultra-wide angle lens giving 180 angle of view. Basically produces a circular image on 35 mm, 5-9 mm lenses showing whole image, 15-17 mm lenses giving a rectangular image fitting just inside the circle, ...
Fisheye Lens: 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) ...
Fisheye Lens Ultra-wide angle lens providing a near 180 angle of view. Fisheye lens produces a rectangular image fitting inside the circle, with highly distorted scene elements.
Fisheye Lens
Fisheye camera lenses distort the subject image, producing photos with curved and convex appearances. The fisheye lens was first developed for astronomy photography that seeks to capture as wide a range of sky as possible.

Having a viewing angle of 180°, 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.

What is "vignetting" ?
Vignetting means that there's a decreasing (=darker) illumination towards the image corners.
Fisheye lenses are useful for three basic things. First, it's a lot easier to make a super wide angle fisheye than it is a super wide angle rectilinear lens, so a fisheye lens is going to be cheaper than its rectilinear equivalent.
With a fisheye lens, the over/under doesn't need to be exactly symmetrical.
A more forgiving means to shoot over/unders is with a full-frame fisheye lens (16mm Nikkor or 15mm Canon).
In general, fisheye lenses are expensive and little used in everyday photography. They are used for measuring, scientific research tasks, especially meteorology, illumination studies, botanic studies on trees.

Ultra-Wide-Angle Lenses Many ultra-wide-angle, or short-focal-length, lenses are known as fisheye lenses. These lenses have a focal length of less than about 17mm (for a 35mm camera).
I did try my hand at wide-angle photography, using a 16mm fisheye lens. The results were not fantastic, but I'm sure it was more down to the operator than the camera.

Fisheye lens: Extreme wide-angle lens covering about 180 degrees. It produces distorted images.
Fixing: Chemical used for fixation of an image.
Flare: Scattered light produced by reflections inside the lens. It reduces contrast and shadow detail.
8 fisheye lens - 220 degree; while the narrowest is Nikon, 2000mm F11 Reflex Nikkor, only slightly over 1 degree of view. It can also be explained as the extent of the view taken in by a lens.
A fisheye lens uses an angle of view up to 180 degrees. The angle distorts the photograph so the four sides appear to be farther away.

Without resorting to fisheye lenses or teleconverters, I can go from all the way from 12mm focal length out to 400mm, an amazing 33x zoom range. And lenses with even longer focal lengths are available, albeit for a price.
This tool can be used to modify images taken with a compatible fisheye lens. It can be used to apply either vertical or horizontal compensation to produce a 'rectilinear image'.

That should say that it's not cheap to make a high-quality fisheye lens for the smaller sensors like the one on your D50 (and the one on my Canon 30D). I doubt that your auxiliary lens cost anywhere near $650-1000.
If you can get close enough - and obviously with tame animals - try using an ultra-wide or fisheye lens to exaggerate the unusual perspective and create amusing caricatures.
Sometimes you can buy a generic brand lens that isn't available in Canon or Nikon models. For example, Sigma sells an 8mm fisheye lens that Canon doesn't make.

be equivalent to in terms of a 35mm film SLR camera. Used as a standard for discussing the field of view and magnification power of a lens. In 35mm equivalency, lenses over 50mm are telephoto, whereas lenses below 50mm are wide-angle or fisheye lens.
Straight lines are bowed in at the edges of the picture frame resembling the sides of a barrel; present in small amounts in some wideangle or wideangle-zoom lenses, but uncorrected in fisheye lenses.
