  2. Wide-angle lens - Wikipedia

    en.wikipedia.org/wiki/Wide-angle_lens

    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

  3. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    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 ...

    en.wikipedia.org/wiki/Panoramic_photography

    While there is no formal division between "wide-angle" and "panoramic" photography, "wide-angle" normally refers to a type of lens, but using this lens type does not necessarily make an image a panorama. An image made with an ultra wide-angle fisheye lens covering the normal film frame of 1:1.33 is not automatically considered to be a panorama.

    Also, wide-angle lenses for narrow-gauge movie cameras had to be of this type because of the shutter mechanism that had to fit in between. [2]: 142–143 In still photography, a single-lens reflex camera requires a space for the reflex mirror, imposing a limit on the use of wide-angle lenses of symmetric designs. The retrofocus lens addressed ...

  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 .
