Rectilinear lens
From Wikipedia, the free encyclopedia
In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the walls of buildings, appear with straight lines, as opposed to being curved. In other words, it is a lens with little barrel or pincushion distortion.
The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.
