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 ...
Fisheye lenses, typical focal lengths are between 8 mm and 10 mm for circular images, and 15–16 mm for full-frame images. Up to 180° and beyond. Up to 180° and beyond. A circular fisheye lens (as opposed to a full-frame fisheye) is an example of a lens where the angle of coverage is less than the angle of view.
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.
Lenses with focal lengths of 8 to 16 mm may be either rectilinear or fisheye designs. Wide-angle lenses come in both fixed-focal-length and zoom varieties. For 35 mm cameras, lenses producing rectilinear images can be found at focal lengths as short as 8 mm, including zoom lenses with ranges of 2:1 that begin at 12 mm.
The 2-shot fish eye camera system was made popular by IPIX in the mid-1990s and a two-shot rotator head that rotated and locked into 0° and 180° positions only. The camera was an Olympus or Nikon CoolPix camera and the lenses used were the Nikon FC-E8 or FC-E9 fish-eye lens. The IPiX 360 camera system enabled photographers to capture a full ...
Lomography is a photographic style which involves taking spontaneous photographs with minimal attention to technical details. Lomographic images often exploit the unpredictable, non-standard optical traits of toy cameras (such as light leaks and irregular lens alignment), and non-standard film processing techniques for aesthetic effect.
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]
"Selfie" is an example of hypocorism – a type of word formation that is popular in Australia, [5] where it was in general use before gaining wider acceptance. [6]The first known use of the word selfie in any paper or electronic medium appeared in an Australian internet forum on 13 September 2002 – Karl Kruszelnicki's 'Dr Karl Self-Serve Science Forum' – in a post by Nathan Hope.
