An ultra wide-angle lens is a lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the size of the sensor in the camera in question. [1] For 1" any 9mm or shorter is considered ultra wide angle. For 4/3" any 10 mm or shorter lens is ...
A year later, Samsung and Phillips announced 'super ultra-wide displays', with aspect ratio of 32:9, for "iMax-style cinematic viewing". [8] Panacast developed a 32:9 webcam with three integrated cameras giving 180° view, and resolution matching upcoming 5K 32:9 monitors, 5120x1440. [ 9 ]
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
For example, for 35 mm film which is 36 mm wide and 24 mm high, = would be used to obtain the horizontal angle of view and = for the vertical angle. Because this is a trigonometric function, the angle of view does not vary quite linearly with the reciprocal of the focal length.
The Biogon is an ultra-wide-angle design by Ludwig Bertele based on a double-ended reversed-telephoto objective. It was made by Zeiss for their 35mm Contax and the medium-format Hasselblad cameras. The design was physically large, being two focal lengths in length and one focal length in diameter.
Extension or wide-angle distortion can be seen in images shot from close using a wide-angle lens (with an angle of view wider than a normal lens). Objects close to the lens appear abnormally large relative to more distant objects, and distant objects appear abnormally small and hence farther away – distances are extended.

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.
