This type of image is known as a "curvilinear" image.įisheye lenses produce noticeable barrel distortion, but this can be used to great artistic effect.
This allows you to create images which cover as much as 360 degrees, making for some very interesting, abstract compositions.įisheye lenses suffer from "barrel distortion", where subjects at the centre of the frame appear to bulge outwards, and straight lines curve wildly.
#Fisheye lens camera software
If you want to capture more than 180 degrees, it is possible to stitch more than one fisheye photo using software such as Photoshop. These lenses tend to be very big, heavy, and expensive, and so are generally only used for specialist, technical work.
However, some manufacturers sell lenses which go even further, up to 220 degrees.
#Fisheye lens camera full
These have even shorter focal lengths, sometimes as low as 1mm, so that they produce a full 180 degree photo.Ī "true" fisheye lens is considered to be one that can capture 180 degrees at the widest point. This will produce a narrower field of view.īecause of this, many manufacturers produce fisheye lenses designed specifically for cameras with smaller sensors. For example, a 10mm fisheye lens on a camera with a crop factor of 1.5 will have an effective focal length of 15mm. To find the equivalent focal length of a lens, you need to multiply its focal length by the camera's "crop factor". Full-frame lenses have slightly longer focal lengths, usually 15mm to 16mm.Īs with all lenses, the focal length is effectively increased for cameras with a sensor smaller than 35mm. This makes them more suitable for practical purposes such as traditional landscape photography and shooting building interiors.įor cameras with a 35mm sensor or film, a typical circular fisheye lens might have a focal length of 8mm to 10mm. The horizontal and vertical sides of the image are less than 180 degrees (typically around 150 degrees horizontal and 100 degrees vertical).įull-frame fisheye lenses cover 180 degrees along the diagonal only, producing a less wide-angle, rectangular photo without the black borders.Īlthough they do not cover such a wide angle, photos taken using a full-frame fisheye lens are rectangular and do not have black edges. These more extreme fisheye lenses tend to be used for artistic purposes such as skateboard photography or for shooting unusual landscapes and cityscapes.Ī full-frame fisheye lens only captures a 180 degree field of view along its diagonal. This results in a circular image, with the edges of the frame being black.Ĭircular fisheye lenses cover 180 degrees in all directions, but have black edges. Each produces a very different effect.Ī circular fisheye lens is one which captures a full 180 degree view in all directions. There are two main types of fisheye lenses, circular and full-frame. They use them to take intriguing photographs of all types of subjects, from still life to portraits.įisheye lenses allow an extremely wide angle of view.
They are also commonly used to photograph action sports such as skateboarding, snowboarding, and surfing.Īs well as being used for practical purposes, many artists have adopted them due to the unusual, distorted images they produce. The images they produce are highly distorted, giving them a dynamic, abstract feel.įisheye lenses are popular for photographing extremely wide panoramas of landscapes and the sky, and for shooting close-up subjects such as crowds, interiors, and architecture. A fisheye lens, also known as an "ultra wide" or "super wide" lens, is a type of wide angle lens which can capture an extremely wide image, typically around 180 degrees.
