An ultra wide-angle lens is a lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the size of the sensor in the camera in question. [1] For 1" any 9mm or shorter is considered ultra wide angle. For 4/3" any 10 mm or shorter lens is ...
Ultra wide angle lenses have a focal length shorter than the short side of the film or sensor [citation needed]. In 35 mm, an ultra wide-angle lens has a focal length shorter than 24 mm. Common wide-angle lenses for a full-frame 35 mm camera are 35, 28, 24, 21, 20, 18, and 14 mm
A year later, Samsung and Phillips announced 'super ultra-wide displays', with aspect ratio of 32:9, for "iMax-style cinematic viewing". [8] Panacast developed a 32:9 webcam with three integrated cameras giving 180° view, and resolution matching upcoming 5K 32:9 monitors, 5120x1440. [ 9 ]
For example, for 35 mm film which is 36 mm wide and 24 mm high, = would be used to obtain the horizontal angle of view and = for the vertical angle. Because this is a trigonometric function, the angle of view does not vary quite linearly with the reciprocal of the focal length.
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.
An image made with an ultra wide-angle fisheye lens covering the normal film frame of 1:1.33 is not automatically considered to be a panorama. An image showing a field of view approximating, or greater than, that of the human eye – about 160° by 75° – may be termed panoramic. This generally means it has an aspect ratio of 2:1 or larger ...
A flat panel 65-inch screen 4K TV usually measures less than 60 inches wide, less than 36 inches tall, and about 15 inches deep with the stand. ... and the widest viewing angle of any TV ...
EF 11–24 mm f/4L USM – an ultra wide angle lens that provides a wider field of view than the 16-35 mm lenses; EF 17-35mm f/2.8L USM – replaced the EF 20-35mm lens f/2.8L and was replaced by the EF 16-35mm f/2.8L USM; EF 17–40mm f/4L – classified as an L-series lens, but is less expensive than any version of the 16–35
