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.
In photography, angle of view (AOV) [1] describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image.
Some fisheye lenses use a stereographic projection to capture a wide-angle view. [26] Compared to more traditional fisheye lenses which use an equal-area projection, areas close to the edge retain their shape, and straight lines are less curved. However, stereographic fisheye lenses are typically more expensive to manufacture. [27]
The Fish-Eye Rokkor 16mm f/2.8 is a prime fisheye lens produced by Minolta for Minolta SR-mount single lens reflex cameras, introduced in 1969 to replace an earlier fisheye lens, the UW Rokkor 18mm f/9.5. It is a full-frame fisheye lens with a 180° viewing angle across the diagonal. This lens was licensed by Leitz and released for Leica R ...
A fisheye lens is a special type of ultra-wide angle retrofocus lens with little or no attempt to correct for rectilinear distortion. Most fisheyes produce a circular image with a 180° field of view. The term fisheye comes from the supposition that a fish looking up at the sky would see in the same way. [1]: 145
Photographic lens design. The design of photographic lenses for use in still or cine cameras is intended to produce a lens that yields the most acceptable rendition of the subject being photographed within a range of constraints that include cost, weight and materials. For many other optical devices such as telescopes, microscopes and ...
Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).
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.
