Considering its spectacular angle of view and overall performance, this FD lens is a very attractive entry lens for super wide-angle photography. It is ideally suited to a wide variety of applications, such as architecture, fashion or journalism. With the incorporation of the Canon Floating System, image quality should be improved even at close focusing distance.

One of the strong points of a 17mm focal length lens is its rectilinear lens design that produces straight lines as straight lines without distortion. It is, therefore, a perfect choice for photographing in tight quarters with a restricted camera-to-subject distance. Buildings with many straight lines are natural subjects for this FD 17rnm lens. Photographing a building from a direct angle with the camera held level will result in a natural looking, undistorted image. But the New FD 17mm f/4 is not a lens intended just for outdoor photography. You may also find it indispensable for indoor photography, particularly where the subject - an interior, for example - is large and the working distance is severely limited.
