2. 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 ...

3. Luneburg lens - Wikipedia

   en.wikipedia.org/wiki/Luneburg_lens

   A Luneburg lens (original German Lüneburg lens) is a spherically symmetric gradient-index lens. A typical Luneburg lens's refractive index n decreases radially from the center to the outer surface. They can be made for use with electromagnetic radiation from visible light to radio waves. For certain index profiles, the lens will form perfect ...

   The first widely-available fisheye lens for 35mm cameras was the Fisheye-Nikkor 8 mm f /8 from Nikon, released in 1962, which produced circular images similar to those popularized by the LIFE photographers; [71] that lens served as the "eye" of the HAL 9000 computer from the film 2001: A Space Odyssey, [72] although scenes depicting HAL's point ...

5. Distortion (optics) - Wikipedia

   en.wikipedia.org/wiki/Distortion_(optics)

   Fisheye lenses, which take hemispherical views, utilize this type of distortion as a way to map an infinitely wide object plane into a finite image area. In a zoom lens, barrel distortion appears in the middle of the lens's focal length range and is worst at the wide-angle end of the range. [2]

6. Canon EF 15mm lens - Wikipedia

   en.wikipedia.org/wiki/Canon_EF_15mm_lens

   Retail info. MSRP. $719.99 USD. The Canon EF 15mm f/2.8 was a fisheye lens produced by Canon from 1987 to 2011. The lens was compatible with all EF camera bodies but only intended for full-frame configurations, as the fisheye effect is much less pronounced with a cropped sensor ( APS-C ). In 2010 Canon announced the EF 8–15mm f/ 4L Fisheye ...

   en.wikipedia.org/wiki/Canon_EF_8-15mm_lens

   MSRP. $1,399 USD. The EF8–15mm f/4L FISHEYE USM is a fisheye zoom lens for Canon digital single-lens reflex cameras (DSLRs) with an EF lens mount. It delivers 180° diagonal angle of view images for all EOS SLR cameras with imaging formats ranging from full-frame to APS-C, and provides 180° circular fisheye images for full-frame EOS models.
