Ultra wide angle lenses have a focal length shorter than the short side of the film or sensor [citation needed]. In 35 mm, an ultra wide-angle lens has a focal length shorter than 24 mm. Common wide-angle lenses for a full-frame 35 mm camera are 35, 28, 24, 21, 20, 18, and 14 mm
Ultra wide angle lens is a rectilinear which is less than 24 mm of focal length in 35 mm film format, here 14 mm gives 114° and 24 mm gives 84° . Wide-angle lenses (24–35 mm in 35 mm film format) cover between 84° and 64° Normal, or Standard lenses (36–60 mm in 35 mm film format) cover between 62° and 40°

Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens, photographic lens or photographic objective is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Cross-section of a typical retrofocus wide-angle lens. Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film ...
Another result of using a wide-angle lens is a greater apparent perspective distortion when the camera is not aligned perpendicularly to the subject: parallel lines converge at the same rate as with a normal lens, but converge more due to the wider total field. For example, buildings appear to be falling backwards much more severely when the ...
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [ 4 ] [ 5 ] : 145 Fisheye lenses achieve extremely wide angles of view , well beyond any rectilinear lens.
It was the first super-wide angle zoom lens for still cameras (most 35mm SLRs). Previously, combining the complexities of rectilinear super-wide angle lenses, retrofocus lenses and zoom lenses seemed impossible. The Sigma's all-moving eleven element/seven group/three cell formula was a triumph of computer-aided design and multicoating. [114]
