The first types of fisheye lenses developed were "circular" — lenses which took in a 180° hemisphere and projected it as a circle within the film frame. By design, circular fisheye lenses thus cover a smaller image circle than rectilinear lenses designed for the same sensor size. The corners of a circular fisheye image will be completely black.
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.
It is a circular fisheye lens, designed to project a 180-degree field of view in all directions onto a circular image. 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.
Hemispherical photograph used to study microclimate of winter roosting habitat at the Monarch Butterfly Biosphere Reserve, Mexico.. Hemispherical photography, also known as canopy photography, is a technique to estimate solar radiation and characterize plant canopy geometry using photographs taken looking upward through an extreme wide-angle lens or a fisheye lens (Rich 1990).
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.
Zenitar (Russian: Зенитар) is a series of Soviet/Russian prime lenses. They were developed and are currently produced by JSC S. A. Zverev Krasnogorskiy Mekhanicheskiy Zavod (KMZ). The series is most commonly known for the 1:2.8 16 mm fisheye lens. Example photo made using MC Zenitar 16mm f/2.8 fisheye lens MC Zenitar-M2,8/16
Sep. 2—Photography is both a fickle mistress and a moving target. One day pictures of models atop mountains are the big thing, then the next big thing is a picture of grass on your knees. Social ...
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]
