The Canon Fd lens series began to release in 1971. The 14mm lens was released in 1984. This is a super wide-angle lens with the shortest focal length of non-fisheye lenses in the FD series. Diagonal angle of view is 114° and maximum aperture is f/2.8. The front surface of the second element in its 10 group, 14 element lens construction has an aspherical surface. The result is an extremely compact optical system. This is how it was introduced in 1984. Lens rehaused by Optex.
