5 reasons to buy an ultra wide lens
Super wide-angle lenses are a very specific class of optics, with their own features and fields of application. The effect they create is very difficult to replicate with other lenses or programs.
Lenses with a field of view of 90 or more degrees on the diagonal of the frame (that is, wider than those of the human eye) and a certain focal length are considered “super-widths”:
for cameras with APS-C matrix – from 15 mm and less;
for full-frame cameras – less than 24 mm.
Such optics is clearly associated with distortions – perspectives and geometry. Here, these lenses are divided into two classes: fisheye (fisheye) and rectilinear (without distortion). Continue reading
