2. Wide-angle lens - Wikipedia

   en.wikipedia.org/wiki/Wide-angle_lens

   In photography and cinematography, a wide-angle lens is a lens covering a large angle of view. [a] Conversely, its focal length is substantially smaller than that of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior, and landscape ...

3. Angle of view (photography) - Wikipedia

   en.wikipedia.org/wiki/Angle_of_view_(photography)

   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°

4. Ultra wide angle lens - Wikipedia

   en.wikipedia.org/wiki/Ultra_wide_angle_lens

   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 ...

5. Fisheye lens - Wikipedia

   en.wikipedia.org/wiki/Fisheye_lens

   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. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...

6. Camera lens - Wikipedia

   en.wikipedia.org/wiki/Camera_lens

   Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses 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.

7. Large format lens - Wikipedia

   en.wikipedia.org/wiki/Large_format_lens

   The term wide-angle lens denotes a lens that has an image circle diameter significantly wider than the lens focal length The Hypergon is a wide angle lens that covers a flat field. It is constructed symmetrically consisting of two deep meniscus elements that almost form a sphere .
