The F-mount has been in production for over five decades, making it the only SLR lens mount which has been produced for over 50 years. The F-mount is also popular in scientific and industrial applications, most notably machine vision. Over 400 different Nikkor lenses are compatible with the system (other details can be found at the Nikkor The Thousand and One Nights site ). The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history.
