Fisheye lenses have the widest field of view of any lens group and they distort the resulting image in a dramatic way. Fisheye lens fall into two categories:
- Circular fisheyes: produce an image usually with a 180 degree field of view and dramatic vignetting resulting in a circular image in the 35mm format. They usually have a focal length around 8mm.
- Full frame fisheyes: also have a 180 degree field of view but they stretch the image of the full film plane. Sometimes this category of fisheyes is known as corrected fisheye lenses.
In general fisheye lenses are expensive and little used in everyday photography.
