<strong>Canon FDn 1200mm f/5.6L
</strong>I made a <a href="http://www.canonrumors.com/2012/12/ef-800-f5-6l-is-ii-other-big-lenses/" target="_blank">post a few days ago about built-in teleconverters</a> and said that the EF 200-400 f/4L IS 1.4x was the first Canon lens with the built-in 1.4x teleconverter technology. While it will be the first production lens to have the feature, Canon did in fact make 5 lenses back in 1984 for the Los Angeles Summer Games in the form of an FDn 1200mm f/5.6L that also had a 1.4x teleconverter built in. All 5 of these lenses were shipped back to Canon in Japan and converterted to EF mount. These lenses then became the legendary made to order EF 1200 f/5.6L without the built-in teleconverter.</p>
<p>If you’ve never heard about the super rare Canon EF 1200 f/5.6L, Bryan at TDP has a great article about his time with the lens. <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-1200mm-f-5.6-L-USM-Lens-Review.aspx" target="_blank">Read it here</a>..</p>
