In a circular fisheye lens, the image circle is inscribed in the film or sensor area; in a diagonal ("full-frame") fisheye lens, the image circle is circumscribed around the film or sensor area. This implies that using a fisheye lens for a different format than it was intended for is easy (as opposed to a rectilinear lens), and may change its ...
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 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.
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]
It is the first such lens to provide the complete circular fisheye effect on crop factor digital SLR cameras, which do not have a full 36x24mm sensor. [1] This lens is available in Canon, Nikon, Sigma, Pentax and Sony mounts. This lens projects a 13mm image circle, which fits nicely in a Micro Four Thirds system frame with an adapter.
Cross-section of Maxwell's fish-eye lens, with blue shading representing increasing refractive index. Maxwell's fish-eye lens is also an example of the generalized Luneburg lens. The fish-eye, which was first fully described by Maxwell in 1854 [5] (and therefore pre-dates Luneburg's solution), has a refractive index varying according to
Peleng 3.5/8A is an 8 mm super-wideangle circular fisheye photographic lens, and is designed as an interchangeable lens for Canon, Nikon, Pentax, Olympus digital or film cameras which have or do not have the instant-return diaphragm automatic control device [clarification needed]. The lens has a variable diaphragm from f/3.5 to f/16.
