Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use a special mapping ("distortion"; for example: equisolid angle, see below), which gives images a characteristic convex non-rectilinear appearance. green tea and the immune systemWebAn M12 lens with a 180° FoV is capable of capturing a 5.7 x 4.27 m (18.70 x 14.02 ft) scene at a 1-meter (3.28 ft) distance.
