The use of aspherical elements in the Canon FD 50mm F/1.2 L Lens eliminates the flare and ghosting that can be a problem in lenses with large maximum apertures. Use of the Floating System helps to maintain image quality from infinity to 0.5 meters. Contrast and other factors important in image quality improve when using the lens at full aperture. Considered compact, the lens' total weight is only 380 grams. This fast lens works well on older, film-based Canon cameras or with digital Canon cameras with the help of an adapter. Even in low light, this lens can produce very sharp images that are worthy of entrance into a photo contest.
