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.
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.
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]
Canon EF 8-15mm lens. 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.
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 . In 2010 Canon announced the EF 8–15mm f / 4L Fisheye USM which replaced the EF 15mm f / 2.8. [2]
The smc Pentax-F 17–28mm Fish-eye f / 3.5–4.5 is the first fisheye zoom lens, manufactured by Pentax for single-lens reflex cameras (SLRs) with a K lens mount.At its widest setting of 17mm, it affords a 180° diagonal angle of view images for all K-mount full-frame SLR cameras; at 28mm, the diagonal angle of view is reduced to 90° on the diagonal.
Originally produced by Minolta, and currently produced by Sony, the AF Fish-Eye 16mm, is a prime Fisheye lens compatible with cameras using the Minolta A-mount and Sony A-mount lens mounts. It is a full-frame fisheye lens with a 180° viewing angle. The front of the lens does not have a mount for filters. Rather a number of filters are built in ...
MSRP. $1000 USD. The Sigma 10mm f/2.8 EX DC fisheye is a photographic lens manufactured by Sigma Corporation. It is a diagonal fisheye lens. Unlike most fisheye lenses, this lens is designed for digital SLR cameras that do not have a full 36x24mm sensor. [1] This results in a much greater fisheye effect than is possible when a full-frame ...
